A 70-year-old man is in critical condition after falling from his bicycle in Acadia National Park.

Park rangers were called just after 1 p.m. on Monday to a report of a crash on the Park Loop Road near the Cadillac North Ridge Trail crossing.

The man, described in a news release from the park as “an experienced road bicyclist,” lost control after his foot came loose from a clip-in pedal.

He was wearing a helmet but suffered significant injuries in the head-first fall from his bike.

Park rangers performed life saving measures at the scene, and the Bar Harbor Fire Department brought the man to downtown Bar Harbor where he was transferred by the LifeFlight of Maine helicopter to the Eastern Maine Medical Center in Bangor.

He remained in critical condition as of Tuesday afternoon.
