Phuket, Thailand One-Week Sailing Itinerary - Best Route, Islands & Tips

Begin with a short southern loop: Phuket → Phi Phi Don → Koh Yao Noi → Phang Nga Bay → Similan Islands, then return to Phuket.

This plan covers the most explored highlights across the Andaman coast, with sheltered anchorages, tiny coves, and a flexible pace for wind and seas. The foundation is safety, up-to-date weather checks, and a reliable motor-sailer setup to handle short hops with comfort while you focus on scenery, beaches, and wildlife.

For a compact option, choose a twin-motor aretwin yacht built for short hops along the range of Phuket’s southern coast. It respects shelf life in the water and makes the most of calm mornings and steadier afternoons.

Day 1 – Phuket to Phi Phi Don (25–30 nm). Depart around 08:00 from Phuket’s marina, ride a steady southern breeze, and anchor off Phi Phi Don’s Long Beach. A quick stroll on the tiny strand at dusk reveals towering limestone cliffs and a gentle horizon line.

Day 2 – Phi Phi Don to Koh Yao Noi (20–30 nm). A short, protected hop with smooth seas. Anchor on Koh Yao Noi’s east coast near Ao Haad/Koh Yao Yai’s welcoming shore, then explore a few beach paths and local markets offering small gifts and shell jewelry from friendly traders along the coastline.

Day 3 – Koh Yao Noi to Phang Nga Bay (20–35 nm). Sail toward the limestone karsts and sheltered coves of Phang Nga. Drop anchor near Panak Island or the village at Koh Panyi, then take a dinghy to a cave entrance and a quiet beach in a tiny, tidal cove. On the way, you may pass a tiny islet named tanga and pause for a tea break on its sand.

Day 4 – Phang Nga Bay to Similan Islands (40–60 nm). Start early to catch the best light across the Andaman Sea, obtain the national park permit, and set course for Koh Miang and Donald Duck Bay on the north end of the group. The most stunning aspect is the crystal water around the granite towers and reef edges, ideal for a snorkeling break if weather allows.

Day 5 – Similan Islands. Spend a full day exploring Koh Miang, Koh Similan, and nearby coves. Choose a sheltered beach for a quiet pause, walk a short nature path for sunset viewpoints, and keep one anchor on a protected lee for calm nights. This stretch offers a natural gift shop line of shells and crafts from island markets, with a few trading posts along the shore.

Day 6 – Return toward Phuket or extend to Kawthaung (optional). If you prefer a shorter week, sail back to Ao Chalong or Phuket Calm Bay with a single long hop and a final beach stop for swimming. If border clearance is arranged, a short extension to Kawthaung, Myanmar, is possible across the southern edge of the range; plan ahead for immigration and port calls.

Day 7 – Phuket arrival and wrap. Re-enter Phuket’s sheltered bays, refuel at a quiet pier near Ao Chalong, and compile notes for future travel. The day finishes with a coastal line of sights along Kata–Kata Noi and Nai Harn, perfect for a final sunset on the southern coast before you begin the next voyage.

One-Week Phuket to Ko Tarutao Sailing Plan

Leave Phuket at dawn on Day 1 and sail directly toward Phi Phi Don, anchoring in a sheltered bay like Tonsai for a calm first night, followed by a mid‑afternoon swim to reset the pace.

For a crew of four, a quad-berth bareboat charter works well, offering proper flexibility while keeping rooms comfortable and the galley within easy reach. Each day plan prioritizes sheltered areas, clear water, and opportunities to explore secret coves along fringed coastlines. Travellers who want to celebrate small wins can time swims with sunsets, then sleep soundly in well‑ventilated sleeping cabins.

Day by day, aim to keep distances modest (roughly 20–40 nm per leg), check the status of weather each morning, and tuck into meals aboard or at waterfront taverns in protected harbours. The north‑to‑south arc along thailands western coast features crystal waters, coral gardens, and dining rooms with fresh options, including local curries and grilled seafood, to fuel your week on the water.

As you advance, you’ll find the route offers both calm waters and dynamic sails, with secret coves and reef systems that reward careful planning. Staying in protected bays minimizes moving at night and maximizes time for swimming, snorkelling, and leisure without compromising safety.

Day-by-Day Route Outline: Phuket to Ko Tarutao via Phi Phi, Koh Lanta, and Trang

Recommendation: hire private catamarans or a pair of boats in a quad-share setup to balance cost and flexibility. Depart Phuket at dawn to maximize daylight, spend the first night near Phi Phi, then press south to Koh Lanta, Trang, and finally Ko Tarutao. You will enjoy endless coves, sandy beaches, and vibrant local culture while keeping provisioning simple with locally sourced supplies.

1. Day 1 – Phuket to Phi Phi

   • From Phuket, set sail in the southeast lanes toward Phi Phi Don; expect 4–6 hours depending on seas and wind.
   • Anchorage options: Tonsai Bay or Loh Dalum on Phi Phi Don; both offer quick land access for provisions and a cultural stroll through the town.
   • Highlights: snorkel along scattered corals near the island walls, spot rays cruising the shallows, and enjoy a sandy sunset along Long Beach.
   • Tip: land can be busy; keep a backup plan to anchor near a quieter cove if needed.

2. Day 2 – Phi Phi to Koh Lanta

   • Distance/time: 2–4 hours cruising south along the Phi Phi coast to Koh Lanta Yai; smoother seas help with a comfortable crossing.
   • Anchorage: Klong Khong or Kantiang Bay, with easy access to local markets for fresh seafood.
   • Highlights: explore three main beaches on Lanta’s long coastline, visit the old town at night, and enjoy a locally prepared dinner aboard.

   • Highlights: revisit favorite spots, swap stories from three memorable passages, and toast with locals at a captain James-approved waterfront venue.
   • Tip: use locally sourced fuel and provisions on the last leg; many boats will anchor near Naka Island for a quick swim before the finish.

Anchorages and Sheltered Moorings for an Overnight Sail

Anchor at Ao Chalong Bay for a calm, sheltered overnight. It offers reliable protection from prevailing winds and quick access to Phuket Town for provisioning. Arrive early to secure a comfortable position and make a quick call on VHF 16 to check guest buoy availability. You’ll sleep with minimal motion, then wake ready to options along the coast.

• Ao Chalong Bay, Phuket – Sheltered in all but the strongest SW fronts, with a sandy bottom and 4–10 m depths in the lee. Use 25–40 m of rode with 2:1 scope; if a buoy is available, consider tying to it for extra security. Call the harbor office before dark to confirm a buoy or a safe stern-to anchorage. Taxi rides into Phuket Town are fast and affordable, making early provisioning practical.
• Naka Island (naka) vicinity – A close, lee-protected area just north of Phuket. Anchor behind the fringing reef or join a resort mooring if offered to cruisers, which reduces risk of dragging in gusts. This spot keeps wind and chop low, and the coconut-fringed shore creates a relaxing morning wake-up call. If you want shore time, a short dinghy ride delivers easy access to a sandy beach for a quiet stroll.
• Koh Yao Yai / Koh Yao Noi – Two islands with multiple lee-side anchorages that stay sheltered as the wind shifts. Hold in 8–14 m over sand or mud; use a 2:1 scope for extra security. A local quad-share taxi can shuttle you to sleepy inland villages or a simple seaside cafe for a cultural break. This route lets you keep cruising toward Phang Nga or Krabi the next day, reaching your next destination comfortably.
• Racha Island (Racha Yai), Patok Bay – A favored overnight with solid protection and scenic shoreline. Hold in 5–15 m, best in sand. Approach from the north to minimize chop; a short walk to white-sand beaches is easy if you’re after a luxurious touch ashore. Sailfish are occasionally spotted offshore at first light, so set your dawn watch and enjoy a peaceful morning on deck.
• Phang Nga Bay (Panak and Hong Islands) – Sheltered lagoons behind limestone walls provide an unusually quiet night. Anchor in 6–12 m on sand or mud, steering clear of shallow patches near cave entrances. If marine park rules permit, consider a mooring buoy to keep the area pristine. Note the possibility of busy day-use boats; plan a late arrival to maintain separation from shore excursions.

Note how these options cluster around lee protections, sandy bottoms, and shore access to keep your overnight comfortable. Reach each stop with ease by planning short hops, then rest and reset before the next leg. For extended legs, kawthaung can be a cultural add-on if you extend your cruise beyond Thailand’s islands; plan early, and call ahead for border and vessel procedures. If you travel with a group, you can coordinate quad-share taxis between shores to maximize time on the water and minimize land transit overhead.

Ko Tarutao Access: Permits, Park Rules, and Island-Hopping Etiquette

Get your Tarutao National Park permit 2–3 weeks ahead; without it, these trips would be delayed at the gate. Bring passport copies, boat details, and a clear itinerary, and choose entry dates depending on season. Acknowledging limited daily quotas, last-minute requests are risky, so please plan well in advance with your operator or park office. If you arrive late, expect a thon of checks and paperwork at the gate.

Park rules center on coral protection, sheltered coves, and clean shores. Do not touch coral formations, remove shells, or feed fish; stay on marked trails and use reef-safe sunscreen. For snorkel trips, keep a respectful distance from wildlife and avoid trampling sands. Use designated moorings; if none exist, the operator should adjust plans to minimize impact and protect nesting areas. These practices safeguard the waters and ensure details seen by visitors stay intact for future generations.

Island-hopping etiquette emphasizes courtesy and safety. Kick off with a clear plan and coordinate with your crew to limit long motor runs; opt for short hops between sheltered bays when possible. Yachts and larger boats should use approved moorings and avoid anchoring on coral or seagrass beds. When snorkel is done, move slowly across reefs and keep gear tidy to reduce gear loss. Please greet rangers and local staff, celebrate a relaxed pace, and leave no trash behind. After each stop, rinse gear, respect quiet hours, and carry a small gift or gesture if offered, acknowledging the park’s history and the ancient stories shared by island communities.

Logistics for the Voyage: Provisions, Fuel, Water, and Emergency Gear

Stock up in Phuket before departure and top up fuel and water at Krabi or Railay to cover a seven-day loop along the andaman coast.

Provisions should cover four to six crew for seven days with a selection of meals that travel well: 4 kg rice, 3 kg pasta, 12–16 cans fish or beans, 2 jars peanut butter, 2 liters cooking oil, tomato sauce, coffee and tea, and a mix of fresh fruit and vegetables for 3–4 days. Pack snacks in resealable bags for quick access during swimming or long hops between destinations. For a single boat, plan 4–5 kg rice, 3–4 kg pasta, 12–15 cans fish/beans, 2 jars peanut butter, 2 liters oil, sauces, and 2–3 kg fresh fruit plus 1 kg greens. Use a small fridge to preserve dairy and perishables, and keep dry goods in a labeled bin. For mornings, oats or porridge with dried fruit make a fast start.

Water planning centers on reliable drinking supplies: bring 60–100 liters for drinking across seven days and 60–80 liters for cooking and cleaning. If there’s no onboard watermaker, refill at Krabi town, Ao Nang, Railay, or Tonsai when possible. Store water in clearly labeled jugs away from fuel and use a compact filtration method if you collect tap water on smaller islands. This keeps swimming breaks comfortable and protects the crew’s health for each destination.

Emergency gear covers safety for all boats and crew: life jackets for everyone; a throwable device; VHF radio; handheld GPS and compass; a first-aid kit with seasickness meds; whistle; flare kit; emergency beacon such as EPIRB or PLB; spare bilge pump; spare anchor and rope; several fenders and basic tools; spare propeller or impeller depending on engine type; waterproof bags; duct tape and tie-down straps. Run a quick man-overboard drill each morning to train the crew, and designate nala to log supplies and check equipment before each stop. This plan does not rely on luck; it uses these means to keep the tour safe and steady, even when the seas tilt toward the caves along Railay and Tonsai. Tie a square knot when securing lines to anchors and fenders for added security.

Fuel strategy centers on a full tank before leaving Phuket and a practical redundancy plan: carry two 20-liter jerry cans for safety, and maintain a reserve that covers roughly 20–30 miles of motoring. For a typical mid-size boat, plan 3–5 hours of motoring per travel day under light to moderate breeze. Distances between key stops run in miles: Phuket to racha (racha) about 12–15 miles, racha to Railay/Krabi vicinity around 10–15 miles, and Railay to Tonsai and Krabi town nearby as shorter hops. Slow cruising lets you enjoy the scenery, make calm swims, and pick a favourite bay for a morning break. If you prefer a single loop, you can pair these legs into either a northbound or southbound tour, always aligning with favourable dates and weather windows.

Planning tips for the route include balancing the selection of destinations with the crew’s energy and the forecast. Choose a few must-see destinations–krabi, railay, tonsai, and the nearby caves–then leave room for spontaneous stops to explore a havens surrounded by karst formations. This approach suits both a fast-paced schedule and a relaxed tempo, letting you swim, snorkel, and explore at a comfortable pace across miles of coastline. For a morning start, map out a route that minimizes long hops on rough seas, keeps you near sheltered coves, and preserves fuel for the longer legs back toward Phuket. Dates and logistics align best when you lock in the favourite anchorages early and keep a flexible plan in case a squall or calm spell alters the square of your intended course.

Best Weather Windows, Tides, and Seasonal Considerations for Southern Thailand

Choose November through February as your primary window for Southern Thailand sailing to maximize calm seas, clear mornings, and relaxed cruising.

The dry season on Phuket's Andaman coast runs roughly November to April, with peak sunshine in December through February. Expect light to moderate winds, seas suitable for catamarans, and morning temperatures in the high 20s to low 30s Celsius. This period keeps coral reefs vibrant and provides long days for snorkeling and island hopping, then returning to a comfortable evening in port. There is a huge abundance of sheltered bays and reef edges to explore over several legs of your cruising plan.

Tidal variations are moderate, with larger spring tides around full and new moons. Plan anchorages in protected bays near reef edges to avoid strong surge, and favor slack-water windows for easier mooring at popular marinas or inshore anchors.

Morning snorkeling offers the best clarity; shelter reefs around Phi Phi, Similan Islands, and Phang Nga Bay host abundant coral and colorful fish. For families, choose calm bays near a marina or coastal coves with shallow, sandy bottoms to minimize discomfort and maximize safe, full days afloat. Looking to balance pace with rest, plan short hops and generous shore days to keep the hearts relaxed.

From May to October, the southwest monsoon brings heavier rain and rougher seas. If you sail during this period, plan shorter hops, shelter at protected bays, and reserve extra time in ports to rest between legs. This window can be ideal for land days, system checks, and building confidence before a winter sailing push.

Carry passport and copies, check visa rules, and review requirementsdietary and health precautions with your provider. Book anchorages and marina berths in advance where possible, especially around Phuket Town and other gateway ports with full-service facilities.

For a balanced itinerary, set a base near a marina, then cruise to small islands by catamarans to enjoy space and stability. Early morning departures let you ride favorable currents and return by midday to a relaxed shore day or family activities on the beach. Make the back-to-back legs comfortable by choosing short hops, shaded stops, and easy snorkeling sites.

Respect coral, keep a safe distance when snorkeling, and avoid stepping on reef heads to protect the abundant underwater foundation that makes Southern Thailand a magnet for marine enthusiasts.
