The hook
Not a swamp but a river — 100 km wide and a few centimetres deep, moving so slowly you can't see it, across a limestone shelf covered in sawgrass, with alligators, wading birds and the only place on Earth where crocodiles and alligators share water.
01Why it's worth it
The Everglades is one of the strangest landscapes in North America, and its strangeness is subtle: no mountains, no overlooks, just a sheet of water sliding south through grass, with tree islands, cypress domes and mangrove estuary where it meets the sea. UNESCO-listed and an International Biosphere Reserve, it's the reason a whole vocabulary exists — hammocks, sloughs, the river of grass. Anhinga Trail delivers alligators and herons at arm's length in the dry season; a canoe through the mangrove tunnels of the Ten Thousand Islands is a completely different park; and a guided slough slog, wading waist-deep into a cypress dome, is the way to actually be in it.
The honest part is that this is an ecosystem in serious trouble, and visitors notice. Drainage and agriculture cut its water flow, and since the 1990s invasive Burmese pythons have collapsed the mammal population — raccoon, opossum and rabbit sightings have fallen by well over 90% in the worst-hit areas. One traveller's summary in an "overrated parks" thread is blunt and not wrong: "Everglades, no wildlife left, the snakes ate everything, well except mosquitos." Birds and alligators remain abundant; the mammals largely do not. Come knowing that, and the dry season matters enormously.
02How to experience it
Come December to April, when water levels drop, wildlife concentrates and the mosquitoes are survivable — summer here is genuinely miserable. Walk Anhinga and Shark Valley for guaranteed alligators and birds, then get on the water: a kayak in the Ten Thousand Islands or a ranger-led slough slog, which is the trip people remember. Skip the airboats inside the park (they're outside it, and loud).
From the locals
Park regulars are split on it in a way worth hearing before you go — it appears in "most overrated" threads for the wildlife collapse, while others list it among the parks that formed them, naming "Shenandoah, Smokies, Everglades" as the eastern grounding before they ever saw the West.
