    Participation Requirements


    Picnicking

    Two picnic tables are provided across from the butterfly garden approximately 1/4-mile down the paved wooded boulevard. No fires are permitted. Please pack out your trash.


    Wildlife Viewing

    Wildlife observation is also outstanding at the park. Northbound in April, and especially while southbound in October, migratory birds are funneled into the Keys by the landform. Many tropical species are resident here, including the white-crowned pigeon, mangrove cuckoo and black-whiskered vireo. Tropical vagrants such as the thick-billed vireo and La Sagra's flycatcher are frequently reported in the park.

    Butterfly-watching has rapidly grown in popularity since the mid-1990s; the park features an incredible diversity of species including the Schaus' swallowtail, silver-banded hairstreak, and both hammock and mangrove skippers. Rare tree snails feed on the lichens and bark of the tropical trees, and can be easily observed by park visitors.
