Thunder Hole
Last Updated: January 2026
Overview
About This Trail
Thunder Hole sits along Acadia’s Ocean Path. A 3.4-mile round trip from Sand Beach gains about 196 feet on a coastal walk, with main viewing via paved paths and stairs. It can crowd quickly, especially at high tide, so stay vigilant near edges and be patient with others. Listen for the thunder of waves as they surge into the inlet and keep off slick granite and out of wave splash range.
