Acadia Compass
Works when
the signal doesn't.
The offline-first field companion for Acadia National Park. One app. No accounts. No cellular required.
Coming soon to the App StoreWorks without signal
The entire trail map, routing engine, tide calculator, and sunrise times run on-device. Airplane mode on the summit is not a problem.
Know before you step on trail
Active trail closures — with reasons and dates — sourced directly from the National Park Service. Cadillac Mountain sunrise times and reservation status. Bar Island tidal crossing windows, calculated to the minute. Shuttle routes with first and last departure times for every stop.
Offline trail map
A topographic trail map covering all of Mount Desert Island, bundled directly into the app. Tap any trailhead or carriage-road junction to plan a turn-by-turn route. Works in airplane mode, deep in the park, everywhere.
Route planning
Hiking, biking, and driving routes between any two points in the park. See distance, elevation gain, and estimated time before you start. Step-by-step turn cues that don't require a data connection.
Hike tracking
Record your hike with GPS. Track elapsed time and distance in real time. Save to Apple Health automatically when you're done. Your data stays on your device — and syncs across your own devices via iCloud, never through any server we run.
Safety alerts
Sunset approach alerts keep you from getting caught on trail after dark. Bar Island tidal window alerts — so you never get stranded on the island.
Built for Acadia.
Every color, name, and data point in Acadia Compass is specific to this park. Not a generic hiking app with an Acadia data pack — a tool built around how people actually visit Mount Desert Island.
