Trailmark — your U.S. National Parks passport

Tap every National Park you've stood in — build a map you keep.

Trailmark is a free national-parks passport. Tap every one of the 63 U.S. National Parks you have actually visited on an original, hand-drawn topographic map and watch your collection fill in — each park stitches on an enamel trail patch and grows your progress ring and your percentile among other visitors. There is no account and nothing to install: your map saves on your device and to a shareable growing-link, so you can pick it back up on any trip or any device. Come back after each visit to add the newest park you have bagged, and press Make my patch-map for a card worth sharing.
