Acadia spans roughly 50,000 acres of rugged coastline and granite mountains. Cell service is unreliable across Mount Desert Island. Weather shifts fast on the coast. Packing smart ensures you are ready for exposed peaks, wooded trails, and rocky beaches.
What kind of clothing should I pack for Acadia?
Layering is essential for the unpredictable coastal weather.
Start with a moisture-wicking base layer. Add a windproof and waterproof jacket. Conditions change rapidly. Exposed summits like Cadillac Mountain reach 1,530 feet (466 meters) and get cold and windy.
What are the best shoes for hiking Acadia?
You need sturdy hiking boots with excellent grip.
The park features 158 miles of hiking trails. Many routes cross slick granite slopes. Sneakers often lack the traction required for wet rock. You will also want good footwear if you walk the 45 miles of unpaved carriage roads.
Do I need a map in Acadia National Park?
Yes, you need a physical map or downloaded offline maps.
Cell phone reception is very poor throughout the park. Do not rely on a live internet connection for navigation.
What should go in my daypack?
Carry enough water, extra clothes, and sun protection.
Bring a reusable water bottle. You can refill it at park stations. Add sunscreen, sunglasses, and a hat for exposed summits. A good daypack holds your layers as the weather warms up.

Do I need bug spray in Acadia?
Yes, you should bring insect repellent.
Ticks and mosquitoes are common in the dense forests. Apply repellent before hiking wooded trails or walking the historic carriage roads. Check for ticks after leaving grassy areas.
What extra items are useful for exploring?
Pack binoculars and a tide chart for coastal exploration.
Binoculars help you spot peregrine falcons and marine wildlife. A tide chart is necessary if you plan to explore tide pools or coastal caves.
What documents do I need to enter?
You must bring a National Parks pass or a printed entrance pass.
A standard private vehicle pass costs $35. It is valid for 7 days. Starting in 2026, non-U.S. residents aged 16 and older pay an additional $100 surcharge. The pass must be clearly displayed through your windshield.
