Bal Harbour Travel Guide

Thunder Hole is a cleft in the granite shoreline of Acadia National Park, Maine, where incoming swells compress trapped air and burst out with a thunderous boom — best at mid-tide on a choppy day. Part of Acadia's dramatic Park Loop Road, it pairs the roar with spray, gulls and the scent of spruce. Steps lead down to a viewing ledge; nearby Ocean Path threads toward Sand Beach and Otter Cliff. A short, sensory stop that captures the wild Atlantic edge of New England.

Cadillac Mountain is the high point of Acadia National Park and among the first U.S. Atlantic-coast places to catch the sunrise. From the top you see the granite islands of Frenchman Bay, the spruce sea and the Atlantic's ragged coast; autumn colour and winter snowcaps differ in mood—a signature spot for stargazing and dawn.

Acadia National Park is the only national park in the northeastern US. On Mount Desert Island, Maine, it features stunning ocean cliffs, rugged coastline, Acadian mountain forests and Cadillac Mountain (highest point on the US East Coast) — the Northeast's most sought-after natural destination. About 190 km² of coastline, mountains and forests. Cadillac Mountain (466 m) offers among America's earliest sunrise views. Jordan Pond Path, Thunder Hole and Sand Beach are iconic. Historic carriage roads built by the Rockefeller family. Bar Harbor nearby offers Maine lobster. Visiting the only northeastern US national park for Atlantic coastal beauty is a classic New England experience.
