Weather at Collier-Seminole State Park Campground 3

Best Time to Camp at Collier-Seminole State Park Campground 3

November through April delivers the best conditions: mid-70s to mid-80s, manageable humidity, and far fewer mosquitoes than summer. Spring (March and April) hits the sweet spot for migratory birds, butterflies, and lush understory color, with lighter crowds than the winter holidays. May through October turns the hammock into a steamy, buggy sauna. Summer mosquitoes are extreme. The park doesn't spray because it's a botanical preserve. So if you visit in the wet season, bring strong repellent, long sleeves, and plan for early morning before heat and insects peak.

About Collier-Seminole State Park Campground 3

Dagny Johnson Key Largo Hammock Botanical State Park sits just off U.S. 1 near Mile Marker 106, protecting the largest surviving West Indian tropical hardwood hammock in the United States. The park offers roughly six miles of shaded trails (mostly paved, some natural surface) through dense forest that shelters 84 protected plant and animal species, with admission $2.50 per person at an honor-box kiosk. This is a day-use botanical preserve; there's no camping.

This park does not have a campground or numbered campsites; it is a day-use botanical/hammock preserve.

Historical Significance

The park is named for Dagny Johnson, a local conservationist whose efforts helped block planned condominium development on this land and preserve it as a botanical state park.

Natural Features and SceneryThe hammock is a dense, enclosed jungle corridor at 36 feet elevation, where Caribbean species. Mahogany, gumbo limbo, wild cotton, mahogany mistletoe. Arrived on ancient ocean currents and now form a closed canopy overhead. You won't find big-water vistas here; the scenery is all shaded understory, smooth bark streaked with rare tree snails, and filtered light falling onto the trail edges. Butterflies, anoles, and songbirds move through the vegetation, and American crocodiles inhabit the surrounding habitat. Poisonwood and manchineel trees are common (stay on marked trails), and the dense cover makes this a birding hotspot rather than a viewpoint park. Parking is limited to about a dozen spaces, and trails follow old paved roads plus side paths that can be rough or poorly marked.

Geological RegionWest Indian tropical hardwood hammock (Florida Keys tropical hardwood hammock)

Scenic ViewsPredominantly enclosed forest and shaded hammock corridors rather than open-water vistas; trails provide intimate woodland scenery.

Go if

Birders and botanists visiting the Keys in winter or early spring get the best of it: cool temps, migratory birds moving through the canopy, and Caribbean tree species you won't find anywhere else in the country. Go early, bring exact change.

Skip if

There's no camping, no water, no hookups, and no facilities worth mentioning, this is a day hike, full stop. Summer visits mean brutal mosquitoes in a preserve that doesn't spray. Some visitors outside the local cultural mainstream have reported unwelcoming interactions, so solo
