The National Park Service has released their Fee Free Days for 2023 whereby you can enter any National Park, including Acadia National Park without paying an entrance fee.
The National Park Service is proposing entrance fee increases for Acadia National Park in 2023 and be required year-round. This would not affect the Annual Half Price Sale for the month of December or Senior, Access, 4th Grade, Military Annual, and Military Lifetime passes.
This might be one of the best little secret spots in Acadia National Park. This easy walk through the woods leads to a secluded beach, and the remnants of a mansion built by "The Father of Acadia National Park."
