10 Best Things to Do in Acadia National Park

Acadia set a new visitation record in 2025 with just over 4 million visits, and most of them arrive for the same handful of spots along Park Loop Road. That's not a complaint — Sand Beach and Cadillac Mountain are famous for good reason — but Mount Desert Island has a quieter half most day-trippers never cross the bridge to see, and I'd feel bad sending you home without at least pointing you toward it. Here's my real list, plus the planning details that actually change how good your trip is.

Best Time of Year to Visit, and Why

I'd go in June, September, or the first half of October, and here's my honest reasoning rather than a repeated rule of thumb. Summer — July and August — is when the Cadillac Mountain reservation windows and the Sand Beach parking lots are most competitive, and the coastal fog can roll in and sit for days. Fall is the bigger draw for a reason: peak foliage usually hits Acadia in the second or third week of October, and it's worth checking Maine's foliage tracker as your dates get close, since the exact week shifts with the weather each year. The catch is that by mid-October the Cadillac summit reservation season is also winding down and nights get genuinely cold. If I had to pick one window, early-to-mid October threads that needle — color in the trees, cooler hiking temperatures, and (during roughly this stretch each fall) Cadillac Mountain gets its "first sunrise in the continental U.S." claim back, which is only actually true from about October 7 through early March.

How Acadia Compares to Shenandoah

I get asked constantly whether someone should do Acadia or Shenandoah if they only have time for one East Coast park, so here's my honest comparison rather than a dodge:

	Acadia	Shenandoah
Terrain	Granite coastline and low mountains meeting the Atlantic	Blue Ridge Mountains, no coastline
Signature drive	Park Loop Road — 27 mi, ties together the coast and Cadillac Mountain	Skyline Drive — 105 mi, the entire length of the park
Entrance fee	$35/vehicle (7-day)	$30/vehicle (7-day)
Signature feature	Cadillac Mountain, the highest point on the North Atlantic seaboard at 1,530 ft	75 scenic overlooks along Skyline Drive
Best for	Ocean views, tide pools, and cliffside iron-rung hikes in a compact area	A longer, more classic mountain fall-foliage road trip

If I had to pick just one, I'd pick Acadia for the coastline and the compact, do-a-lot-in-a-weekend size of it, and Shenandoah if a long scenic drive through the mountains is more the trip I'm after. Both peak for foliage in roughly the same October window, so I've genuinely considered doing them back to back on one fall trip.

Hiking Checklist — Acadia National Park

Obviously, for anything beyond a short walk, you'll want real hiking gear, not just sneakers and a water bottle. Here's what I actually bring on every hike in Acadia:

1. Real hiking shoes with grippy soles — Acadia's granite gets slick when wet, and the iron-rung trails demand more traction than sneakers give you.
2. A packable rain shell or windbreaker — coastal weather changes fast, and fog can roll in off the water with almost no warning.
3. Layers, even in summer — it's noticeably colder and windier on exposed granite ridgelines and at the Cadillac summit than it is at sea level in Bar Harbor.
4. A 1.5–2L water supply — shorter trails than out West, but the granite scrambles are more physically demanding than the mileage suggests.
5. A tide chart or tide app — several coastal spots, including Thunder Hole, are only worth timing around high tide; low tide can be a non-event.
6. Sun protection — hat and sunscreen, especially for the fully-exposed granite stretches on the Beehive and Precipice-style trails.
7. Your Cadillac Summit Road reservation confirmation, printed or downloaded — cell service near the entrance can be patchy, and rangers do check.

The 10 Best Things to Do in Acadia National Park

1. 1. Cadillac Mountain

   At 1,530 ft, the highest point on the North Atlantic seaboard, and — for roughly mid-October through early March — the first place in the continental U.S. to see the sun rise. Drive up with a reserved Summit Road permit, or hike or bike up for free, no reservation needed. Drive: 30 min. Trail: 4.4 mi RT, strenuous, ~3 hrs.

2. 2. The Beehive Loop

   A short but genuinely thrilling climb up iron rungs and exposed ledges above Sand Beach. Not for anyone nervous about heights, but the views are completely disproportionate to the distance. 1.4 mi loop, strenuous, 1.5–2 hrs.

3. 3. Precipice Trail

   Acadia's other, even more famous iron-rung route, up the sheer east face of Champlain Mountain. It's closed most springs and summers for peregrine falcon nesting, so I'd check current status before planning around it — hiking it while closed is a federal offense. 2.1 mi RT, strenuous, 2–3 hrs.

4. 4. Jordan Pond Path + Popovers

   A flat loop around the park's most photographed pond, framed by the twin peaks of the Bubbles, ending at the Jordan Pond House — serving popovers and tea on the lawn since the 1890s. 3.3 mi loop, easy, 2 hrs.

5. 5. Park Loop Road

   The 27-mile road connecting nearly everything on this list — Sand Beach, Thunder Hole, Otter Cliffs, and Jordan Pond — with several one-way sections, so I'd plan to commit to the full loop rather than backtrack.

6. 6. Ocean Path Trail

   A flat, easy walk along the coastline from Sand Beach past Thunder Hole to Otter Cliffs. Time it near high tide if you want Thunder Hole to actually perform. 2.2 mi RT, easy, 1.5–2 hrs.

7. 7. Great Head Trail

   A loop over a rocky headland right next to Sand Beach, with some of the better ocean views in the park for the relatively modest effort involved. 1.7 mi loop, moderate, 1.5 hrs.

8. 8. St. Sauveur and Acadia Mountain Loop

   On the island's western, much quieter half, across Somes Sound — often described as the only fjord-like inlet on the U.S. East Coast. Real climbing, real views, a fraction of the crowds. 3.9 mi loop, strenuous, 2.5–3.5 hrs.

9. 9. Jordan Cliffs and Sargent Mountain Loop

   A longer, more demanding day that trades the coastline for the island's interior peaks — Sargent Mountain is the second-highest point in the park. Good pick if you've already done Cadillac and want a bigger climb with fewer people. 5 mi loop, strenuous, 3–4 hrs.

10. 10. Schoodic Peninsula

    The only part of Acadia on the mainland rather than Mount Desert Island, reached by a short ferry or a longer drive around. Its trail network sees a fraction of the visitors the main island does, and the rocky shoreline is every bit as dramatic. 7.5 mi trail network, moderate, varies.
