St Johns US National Park has placed underwater plaques along an underwater “snorkeling trail” that describes the coral, fish, and underwater life. It’s hard to compare two snorkeling spots, but in some ways, this was one of the best snorkeling spots we’d visited. Make sure to bring your National Parks Pass and your snorkeling gear! They had places for food, excellent showers and restrooms, and some shops for sun tan lotion, etc. Snorkeling Trunk Bay was a fantastic experience for us; a definite repeat.
