Acadia National Park is small enough to sample in a day and dense enough to leave you wanting two more. The first-time playbook is a Park Loop Road sampler with one short hike, lunch in Bar Harbor, and either Cadillac Mountain at the end or Bass Harbor Head Light at sunset.
The single most important 2026 planning fact: Cadillac Summit Road requires a timed-entry reservation from May 20 through October 25, separate from the entrance pass.
Before you go
- Entrance fee: $35 per vehicle for a 7-day pass. America the Beautiful annual pass works. Park is cashless
- Cadillac Summit Road timed-entry: required May 20 to October 25, 2026. $6 reservation fee on recreation.gov in addition to the entrance pass
- Park Loop Road: 27 miles, mostly one-way in summer; the spine of any first visit
- Cadillac Mountain: 1,530 ft, highest point on the US East Coast
- Sand Beach: the only sand beach on Mount Desert Island
- Best season: late June through October; July to August is peak
- Free Island Explorer shuttle runs late June through mid-October
- Drive from Boston: about 5 hours; from Bangor about 1 hour
Active 2026 closures and notes
- Cadillac Summit West parking lot (Blue Hill Overlook) is closed for construction through May 19, 2026; the road itself opens for timed-entry on May 20
- Park Loop Road from Kebo Street to Sieur de Monts: closed April 13 through June 12, 2026 (Memorial Day Weekend excluded), for road work
- Storm erosion from January 2024 has affected access points at Sand Beach, Little Hunters Beach, and Otter Cove; some pull-offs and stair access remain limited
A one-day plan
| Time | Stop | Why it works |
|---|---|---|
| 6:30 to 8:00 am | Sand Beach + Ocean Path to Thunder Hole | Cool air, soft morning light, easier parking |
| 8:00 to 10:00 am | Drive Park Loop Road, stop at Otter Cliff and Otter Cove | The classic ocean-meets-granite scenery |
| 10:00 to 11:30 am | Jordan Pond Path (3.2 mi loop, easy) | Iconic photo stop with the Bubbles in the distance |
| 12:00 to 1:30 pm | Lunch in Bar Harbor | Many options; Jordan Pond House popovers can be a long wait at peak |
| 2:00 to 4:00 pm | Bass Harbor Head Light or Schoodic Peninsula | Quieter afternoons; the lighthouse is one of Maine’s most-photographed |
| 5:00 to 7:00 pm | Cadillac Mountain summit (with reservation) | Sunset over the islands from the East Coast’s highest point |
Park Loop Road: the spine of the day
The 27-mile Park Loop Road is mostly one-way during the busy season. Drive it clockwise from Hulls Cove or Bar Harbor for the natural flow of stops. Major pull-offs in driving order:
- Schooner Head Overlook — short walk to a coastal viewpoint
- Sand Beach — the only sand beach on the island; cold water
- Thunder Hole — a small rock cleft where waves boom on incoming tides. Best 1 to 2 hours before high tide
- Otter Cliff — 110-foot granite headland with crashing surf
- Otter Cove and the seawall
- Jordan Pond House — restaurant + Jordan Pond Path trailhead
- Cadillac Mountain Summit Road turnoff (requires reservation in season)
Hikes worth knowing
- Jordan Pond Path — 3.2 mi loop, easy, mostly flat with a wooden boardwalk on the west shore. See the Jordan Pond Path loop guide for the Bubbles side trip
- Ocean Path — 4.4 mi RT one-way from Sand Beach to Otter Point; coastal cliffs, optional ending at Otter Cliff
- Beehive Trail — 1.4 mi RT, strenuous; iron-rung climb with significant exposure. Not for first-timers or anyone with fear of heights
- Precipice Trail — similar iron-rung climb; closed seasonally (spring through summer) for falcon nesting
- Cadillac North Ridge Trail — 4.4 mi RT, moderate; an alternative to driving up
- Acadia Mountain Trail — 2.5 mi loop, moderate; quieter western side of the island
Cadillac Mountain reservations
From May 20 through October 25, 2026, vehicles need a timed-entry reservation to drive up Cadillac Summit Road. The system works like this:
- Reserve at recreation.gov; $6 reservation fee on top of the $35 entrance pass
- Two booking windows: 90-day rolling window opens at 10 am ET each day; a smaller 2-day window opens at 10 am ET two days before
- Sunrise slots sell out fastest, sometimes within seconds of release
- Reservations specify a 30-minute arrival window; once parked, you can stay as long as the lot allows
- Walking, biking, or hiking up doesn’t require a reservation
If you can’t get a reservation, the North Ridge Trail (hike up) and the Cadillac Summit Loop (after hiking) remain accessible.
Schoodic Peninsula and Isle au Haut
Two parts of Acadia sit off Mount Desert Island and are worth knowing for a second visit:
- Schoodic Peninsula — the only mainland portion of Acadia, on the east side of Frenchman Bay. Quieter than MDI; about a 1-hour drive from Bar Harbor or accessible by ferry in summer. Bass Harbor-style coastal scenery without the crowds
- Isle au Haut — Acadia’s remote island unit, accessible by mail boat from Stonington. Limited trails and primitive camping; permit required for overnight
Where to base yourself
- Bar Harbor — closest, busiest, with the most lodging and dining. Books out far in advance for July to August
- Northeast Harbor or Southwest Harbor — quieter “quiet side” alternatives
- Blackwoods Campground — the main in-park campground; reserve months ahead
- Schoodic Woods Campground — on the Schoodic Peninsula side
For a longer plan, see the Acadia National Park map guide and the two-day Acadia itinerary. For a sibling East Coast park, the Shenandoah National Park map covers the closest Mid-Atlantic option.

Frequently asked questions
Do I need a Cadillac Mountain reservation in 2026?
Yes, from May 20 through October 25 to drive up. $6 reservation on recreation.gov plus the standard $35 entrance pass. Walking, biking, or hiking up the North Ridge Trail doesn’t require a reservation.
How much does Acadia cost to enter?
$35 per vehicle for a 7-day pass. Motorcycles $30, per-person $20. America the Beautiful annual pass works. The park is cashless, so bring a card.
Is one day enough for Acadia?
For the Park Loop Road and one short hike, yes. Two days lets you add either Schoodic or one of the harder hikes (Beehive, Precipice when open) plus a longer trail like the Bubbles or Cadillac North Ridge. Three days opens up Isle au Haut or quieter west-side trails.
What’s the best hike for first-timers?
Jordan Pond Path (3.2 mi loop, easy, mostly flat). The west shore is a wooden boardwalk over wetlands and the views back at the Bubbles are the iconic Acadia photo. Ocean Path between Sand Beach and Otter Point is the next-best easy option.
When is Thunder Hole best?
One to two hours before high tide, when incoming waves are big enough to boom into the rock cleft. Check the NOAA tide chart for Bar Harbor. At low tide there’s not much to see; at slack high tide the waves are weaker.
