AUGUSTA – From now until October, visitors to Acadia National Park will only be able to explore the picturesque Bubble Pond by riding free park buses and bicycles.

The park says the move temporarily banning private vehicles from the pond’s 11-space parking area is to improve safety and bus circulation in an area long known for congestion and illegal parking.

From June 23 to Oct. 10, visitors can ride the Island Explorer bus to Bubble Pond for free through the Loop Road and Jordan Pond routes.

Acadia National Park Superintendent Kevin Schneider called Bubble Pond the park’s “most challenging bus stop.”

The park will be studying the change as it develops a transportation plan for Acadia National Park.

The Bubble Pond parking area will reopen to private vehicles Oct. 11.
