One Day in Acadia National Park

A realistic single-day route through the busiest corner of Mount Desert Island.

By Chris Hayworth, Nestward

Acadia packs a lot into a small footprint: rocky Atlantic headlands, glacier-carved ponds, and 158 miles of trails, most of it clustered on the eastern side of Mount Desert Island. One day isn't enough to see it all, but it's plenty to see the highlights if you stay on one loop and don't try to be a hero. Here's a route that works.

Before you go: the timed-entry reservation

Acadia is one of the ten most-visited national parks in the country, with around 4 million visits a year, and it manages the crowds with a reservation system you should know about before you arrive.

• Cadillac Summit Road requires a timed-entry vehicle reservation (about $6, separate from the entrance fee). It's the only part of the park that needs one, and it's the part everyone wants for sunrise. Book it in advance; they go fast.
• The $35 vehicle entrance pass is good for seven days and covers everyone in your car. You do not need a Cadillac reservation to enter the rest of the park. Only to drive up that one road.
• If you skip the Cadillac reservation, you can still hike up via the North Ridge Trail, or just start your day on the Park Loop Road instead.

Morning: Cadillac Mountain and the Park Loop Road

If you scored a sunrise reservation, drive up Cadillac early. At 1,530 feet it's the tallest point on the eastern seaboard, and for part of the year it's the first place in the U.S. to catch the sunrise. Bring a warm layer. It's windy and cold up there even in summer, when island temperatures still dip toward 45°F at dawn.

From Cadillac, head down to the one-way Park Loop Road, the spine of any Acadia day. Your first real stop is Sand Beach, a pocket of sand tucked between granite cliffs. The water tops out around 55°F, so it's more a place to stand and look than to swim. From the same lot you can pick up the Great Head Trail, a roughly 1.5-mile loop over the headland with big ocean views, a solid leg-stretcher if you have an hour.

Midday: Ocean Path and Otter Cliffs

Just past Sand Beach, the Ocean Path runs about two miles one-way along the shore to Otter Point. It's mostly flat, well-trodden, and arguably the best bang-for-buck walk in the park: crashing surf, pink granite, and a stop at Thunder Hole, where waves slam into a narrow inlet and (when the tide and swell cooperate) boom. Time it for a rising tide an hour or two before high tide for the best chance of a real "thunder."

Keep going and you'll reach Otter Cliffs, a sheer wall of rock dropping straight to the sea, one of the most photographed spots on the coast. Turn around here and walk back, or shuttle a car. This is a good lunch window; pack one, because options inside the park are limited.

Afternoon: Jordan Pond

Cap the day at Jordan Pond, a clear glacial pond framed by two rounded peaks known as the Bubbles. The Jordan Pond Path circles the water in about 3.3 miles, mostly easy except for some stretches of stepping stones and a small bridge, so solid footwear helps. If you're spent, just walk the southern shore for the classic view of the Bubbles reflected in the water and call it.

The historic Jordan Pond House sits at the south end if you want tea and popovers, an Acadia tradition that long predates the national park.

Logistics, kids, and dogs

• Beat the parking crush. Sand Beach and Jordan Pond lots fill by mid-morning in summer. The free Island Explorer shuttle connects most major stops and lets you skip the parking hunt, though it does not serve Cadillac Mountain.
• Best timing. Late June through early October is peak. Fall foliage (late September into October) is stunning but busy. Mornings are always calmer than afternoons.
• With kids: Sand Beach, Thunder Hole, and the flat Ocean Path are the easy wins. Pick up a Junior Ranger booklet at the Hulls Cove Visitor Center. Skip The Precipice: it's a cliff climb with iron rungs and is not for young children.
• With a dog: Acadia is unusually dog-friendly for a national park. Pets are allowed on most hiking trails and carriage roads on a leash no longer than six feet, including the Jordan Pond Path and Ocean Path. The big exceptions: dogs are not allowed on Sand Beach (mid-May through mid-September), on ladder trails like The Precipice, or inside buildings. Still leash up and pack out waste. These privileges are the exception, not the rule, across the park system.
