Acadia’s Coastal Greatest Hits
The Ocean Path connects Acadia’s most famous coastal landmarks in a single walk. Sand Beach, Thunder Hole, Monument Cove, Otter Cliff, and Otter Point are all linked by 2.2 miles of trail that hugs the shoreline with the Atlantic Ocean on your left the entire way. Walk it both ways for a 4.4-mile round trip, or arrange a shuttle and make it one-way.
This is not a wilderness hike. The first section from Sand Beach to Thunder Hole is partly paved and wheelchair-accessible. Tour buses stop at Thunder Hole. Crowds fill the pulloffs on summer afternoons. But none of that diminishes the coastline itself. The pink granite, the crashing surf, the spruce trees leaning away from the prevailing wind, the raw interface of rock and ocean. It is the Atlantic coast at its most dramatic, and you can see it all in a couple of hours at a walking pace.
For families with small children, for people who do not hike, for anyone visiting Acadia for the first time, the Ocean Path is where to start. And for experienced hikers who have done the Beehive and Precipice and Cadillac, the Ocean Path is where you come back to when you want to slow down and just look at the ocean.
The Walk
Sand Beach to Thunder Hole (0.7 miles)
The trail begins at the Sand Beach parking lot, behind the restrooms. This section is the most developed: a mix of concrete and packed gravel, mostly flat, with benches along the way. The path stays above the rocky shoreline with frequent overlook points. On a calm day, the water below shimmers in shades of green and blue against pink granite. On a stormy day, waves send spray across the rocks.
Thunder Hole is a narrow inlet in the granite where incoming waves compress into a cave-like slot and explode upward with a deep booming sound. The effect is best at roughly half tide with incoming swells. If conditions are right, the spray can reach 40 feet. A viewing platform and metal railings keep spectators safe, but rogue waves have injured people who climbed down onto the rocks. Stay behind the railings.
Thunder Hole to Monument Cove (0.5 miles)
Past Thunder Hole, the pavement ends and the trail becomes a gravel and rock path. The crowds thin. The coastline gets wilder. Monument Cove is a small rocky beach tucked between granite walls, named for a distinctive sea stack that once stood here (it has since collapsed). The cobblestones in the cove are smoothed by centuries of wave action and make a satisfying sound when the surf rolls over them.
Monument Cove to Otter Cliff (0.5 miles)
The trail climbs gently through a stretch of spruce forest before emerging at Otter Cliff, the highest coastal headland in Acadia at 110 feet above the water. The cliff face is a sheer wall of pink granite that drops straight into the Atlantic. Rock climbers use the face regularly, and you can often watch them from the trail above. The view south from Otter Cliff stretches to the outer islands.
Otter Cliff to Otter Point (0.5 miles)
The final section descends past Otter Cove to Otter Point, a low granite headland with tide pools and sweeping views. This is a good turnaround point. The Otter Point parking area has space if you want to start from this end instead.
When to Go
Spring
Fewer crowds, dramatic surf from spring storms. Park Loop Road opens mid-April. Can be chilly and windy along the coast.
Summer
Warmest weather, longest days. Thunder Hole crowds peak in afternoon. Start early or walk south-to-north from Otter Point for a quieter experience.
Fall
Thinner crowds, crisp air, excellent light for photography. The contrast of golden foliage against ocean and granite is peak Acadia.
Winter
Park Loop Road is closed to vehicles, but you can walk or bike in. The coastline in winter is dramatic and deserted. Dress for wind.
Practical Notes
Thunder Hole gets all the attention, but the real gem on this walk is the stretch between Monument Cove and Otter Cliff. That is where the crowds disappear and the coastline gets personal. Spend your time there, not waiting in line at Thunder Hole.
The Sand Beach parking lot fills by 9 AM in summer, sometimes earlier. The Otter Cliff lot fills slightly later. The Island Explorer bus (Route 3, Sand Beach line) stops at Sand Beach, Thunder Hole, and Otter Cliff, making shuttle logistics easy and free with your park pass.
Dogs are allowed on leash (6-foot maximum). Between May 15 and September 15, dogs are only allowed on Sand Beach long enough to cross to the trail. They are welcome on the rest of the Ocean Path year-round.
Bathrooms are at Sand Beach and at the Fabbri picnic area near the Gorham Mountain trailhead.
Thunder Hole is loudest and most dramatic about 1.5 to 2 hours before high tide with incoming ocean swells. Check the tide chart and wave forecast before your visit. At dead low tide or on a flat-calm day, Thunder Hole is just a quiet crevice in the rock.

Getting There
The most common starting point is the Sand Beach parking lot on Park Loop Road in Acadia National Park. From Bar Harbor, follow signs for Park Loop Road. Sand Beach is about 10 minutes from the village.
You can also start from the Otter Cliff or Otter Point parking areas at the southern end. The trail is easy to access from multiple points along Park Loop Road.
Parking: Sand Beach lot has roughly 100 spaces. Otter Cliff lot is smaller. Both fill early in summer. Use the free Island Explorer bus to avoid parking stress.
Shuttle: Island Explorer Route 3 runs from Bar Harbor Village Green to Sand Beach, Thunder Hole, and Otter Cliff. Free with park pass. Late June through Columbus Day.
FAQ
Is the Ocean Path wheelchair accessible?
The section from Sand Beach to Thunder Hole is largely smooth concrete and packed gravel, and is the most accessible part. Beyond Thunder Hole, the path becomes uneven gravel and rock, which is not wheelchair-friendly.
How long does the Ocean Path take?
Walking the full 2.2 miles one way takes about 1 to 1.5 hours at a relaxed pace. Add time for stops at Thunder Hole, Monument Cove, and Otter Cliff. A round trip with lingering takes 2 to 3 hours.
When is the best time to see Thunder Hole?
About 1.5 to 2 hours before high tide, with incoming ocean swells. Calm days and low tide produce little to no effect. Check the tide chart and marine forecast before planning your visit around Thunder Hole.
Can I swim at Sand Beach?
You can, but the water temperature rarely exceeds 55 degrees Fahrenheit, even in August. Most people wade in and come right back out. It is beautiful to look at, challenging to swim in.
