About Ocean Path
The Ocean Path follows Park Loop Road along the island’s most exposed eastern coast, between Sand Beach and Otter Point, for about 3 km of almost-flat trail. On the seaward side there are slabs of pink granite where you can descend and sit near the water; on the land side are fir forest and the road.
Sand Beach, at the start of the path, is a small cove between rocks, with sand largely made of fragments of shells and sea urchins. The water is usually below 15 °C even in August. From the beach a short trail leads to Great Head, a promontory with sea views.
Thunder Hole is a narrow rock fissure. When a wave enters forcefully, the air trapped inside is expelled at once and the sea bursts upward with a boom. A platform with a railing lets you watch closely. The effect is usually stronger about two hours before high tide and with rough seas; on calm days it barely happens.
Further on, Otter Cliff rises about 18 meters above the sea and is used for rock climbing. The path ends at Otter Point, which offers views of the bay and offshore islands.
Before you go
Practical information
Cidade Turismo reviews its information regularly, but something may have changed. Check with the place before planning your trip.
How much time to set aside
About two hours for the entire out-and-back trail, including stops at Sand Beach and Thunder Hole.
Best time
Thunder Hole is usually more impressive in the hours before high tide with rough seas; check the tide table. Early morning has fewer people and light that faces the rocks.
How to get there
Via Park Loop Road, from the Sand Beach or Thunder Hole parking lot, about 8 km from downtown Bar Harbor. The Island Explorer stops at Sand Beach in season. This section is inside the park’s paid area.
Tip
Stay behind the railing at Thunder Hole and away from wet rocks at the water’s edge: larger waves can arrive without warning. If you plan to enter Sand Beach’s water, be prepared for the cold.
