This short, fully accessible trail travels along a boardwalk that passes through a mangrove tunnel in one of Florida's most well-known state parks. The hike is a great option for all skill levels and is a good activity to do before or after exploring the reef by glass bottom boat or paddling the state park's clear waters. Hiking the trail in the winter is best as the remainder of the year Mosquitos are a real nuisance.
