At Dagny Johnson Key Largo Hammock Botanical State Park, visitors can traverse more than 6 miles of accessible nature trails by bicycle or on foot. The park was named for Dagny Johnson, a local environmental activist. It's also home to one of the country's largest tracts of West Indian tropical hardwood hammock. The park features 84 protected plant and animal species, including flora like mahogany mistletoe and fauna like the American crocodile. For added convenience, visitors will find a picnic pavilion, as well as on-site restrooms. Most of the trails are paved, making them accessible to wheelchair users.

Recent travelers said the park is a relaxing place to stop and explore for a bit, noting that the park's relatively small size and paved trails were easy to manage for visitors of all ages. However, they stressed to load up on bug spray to combat the droves of mosquitos – especially during the summer.

Dagny Johnson Key Largo Hammock Botanical State Park is open 365 days a year between sunrise and sunset. Admission costs $2.50 per person and is based on the honor system; all visitors should place exact change into a box upon entry. Guests can also pay online if they do not have cash on them. To learn more, visit the park's official website.

#1 John Pennekamp Coral Reef State Park

Named after John D. Pennekamp, a former newspaper editor for the Miami Herald and noted Everglades conservationist, John Pennekamp Coral Reef State Park was developed in 1963 as the United States' first park under the sea. The state park is 25 miles long and 3 miles wide, and it is home to many aquatic plant and animal species, in addition to mangroves and various types of birds.

Visitors can enjoy the park in a number of ways. Water enthusiasts can admire colorful coral reef and the popular Christ of the Deep underwater statue on snorkeling and scuba diving tours, while those who would rather stay dry can sign up for a glass-bottom boat tour. There are also 47 campsites and designated spots for swimming, fishing and picnicking.
