Outdoorsy types will love this database of national and state parks and public lands. Search by proximity for instant results, or filter them by activity — from camping to cycling to spelunking — for a list of nearby parks that accommodate those pursuits. For each place there's a description, an activities list, and sometimes a photo.
WIRED Lists nearby attractions; links to maps.
TIRED Not enough photos to give a sense of what the parks are like. Doesn't include municipal parks.
