John Pennekamp Coral Reef State Park: A Marine Wonderland
Location: Mile Marker 102.5, Oceanside
Access: Entrance fee required
One of the most iconic destinations in Key Largo is John Pennekamp Coral Reef State Park, the first undersea park in the United States. This reef state park offers two main beach areas: Far Beach and Cannon Beach. Both provide opportunities for sunbathing, picnicking, and even snorkeling straight from shore.
Far Beach: A Calm, Family Friendly Retreat
Far Beach is ideal for a relaxing beach day. Its calm, shallow waters and soft sand make it perfect for families with small children. You’ll find picnic tables nestled under palm trees, making it easy to enjoy a meal after a refreshing swim.
Far Beach is also known for its peaceful ambiance, far from the crowds, allowing visitors to fully appreciate the natural beauty around them. It’s also one of the best places for a quiet afternoon with a book or some meditation by the water.
Cannon Beach: History Meets Nature
At Cannon Beach, visitors can snorkel just a few feet from shore to explore submerged artifacts like replica cannons, giving the beach its name. The water here is clear and calm, offering great visibility for spotting fish and coral fragments.
This area is part of the Pennekamp Coral Reef ecosystem, and it’s a fantastic place for those who want a taste of the marine world without going on a full excursion. It’s also conveniently located near rental stations for snorkel gear, kayaks, and paddleboards.
Harry Harris Park: A Family Friendly Favorite

Harry Harris Park is one of the most popular beaches located in Key Largo. With a man-made beach, protected swimming area, and extensive recreational facilities, it’s perfect for families looking for a fun and safe environment.

Hidden Gems and Lesser-Known Beaches
