Pay attention to the tides. If you don’t cross back before the tide comes in, you have to wait 9 hours for the land bridge to be exposed again or pay for an expensive water taxi (which you’ll need to call).

An entrance pass for Acadia National Park is required between May 1 and October 31.

Wear closed-toe shoes with good traction. There’s uneven terrain as well as ticks, so stay in the middle of the trail and away from soil and brush to minimize tick encounters.

You can drive over the land bridge, but you cannot park on it.

You can explore the tide pools and the island, but do not collect anything from the island or land bridge.

Dogs are allowed on the trail, but must be kept on a 6-foot (1.8-meter) leash.
