The largest old-growth bottomland hardwood forest in the US — a cathedral of towering cypress and tupelo.
March–May and October–November: comfortable temperatures and fewer mosquitoes. Late May brings the synchronous firefly show.
The firefly event (by lottery) draws the biggest crowds; the rest of the year is quiet.
Summer is hot, humid and buggy, and the boardwalk can flood after heavy rain.
