BAR HARBOR, Maine — A hiker from Kittery was airlifted Saturday morning from Acadia National Park to a Bangor hospital after falling about 50 feet from a rock face near Sand Beach, according to authorities.

Kevin Hills, who is in his early 20s, reportedly was climbing rocks with his brother-in-law behind a beach cove known as “Old Soaker” when he lost his footing and fell to the cobblestone beach below.

“He got hit by some loose rocks during the fall and had a head laceration, bruises, cuts and scrapes,” Park Ranger Chris Wiebusch, who was among those who responded to a 911 call reporting the accident around 11:30 a.m. “A park lifeguard was the first one to get to him and, because the tide was high, had to swim through the water to reach him onshore.”

Working with the Bar Harbor Fire Department, the Mount Desert Island Search and Rescue Team and a U.S. Fish and Wildlife Service officer, National Park Service personnel used a raise-and-lower system to bring Hills in a litter from the beach to the clifftop roadway. From there an ambulance took Hills to a Main Street baseball field in Bar Harbor that is used as a LifeFlight helicopter landing zone. The rescue operation took about three hours.

Hills reportedly was taken to Eastern Maine Medical Center.

“He never lost consciousness,” Wiebusch said of Hills. “He was a very stable patient, which meant there was no need to hurry in getting him to the top.”
