Acadia warns of a busy season

Acadia National Park is telling visitors to expect heavy crowds this year and to lock in key reservations before they arrive. (nps.gov) The National Park Service said on April 14 that the 2026 summer season will be “BUSY,” and said most of Park Loop Road opens to motor vehicles on April 15. A section between Kebo Street and Sieur de Monts will stay closed through June 12, except for Memorial Day weekend. (nps.gov) The biggest choke point is Cadillac Mountain. Acadia requires vehicle reservations for Cadillac Summit Road from May 20 through October 25, with 30 percent released 90 days ahead and 70 percent released at 10 a.m. Eastern two days before each date. (nps.gov) That road is also not fully available yet. The summit road is closed through May 19 while crews build a pedestrian walkway connecting the two summit parking areas, though hiking trails to the top remain open. (nps.gov) Park officials are pushing visitors toward the Island Explorer bus system instead of private cars at the busiest stops. The fare-free service starts spring operations on the Gateway Center, Loop Road and Schoodic routes on May 20, and other routes begin June 23. (exploreacadia.com) The Loop Road bus runs every 30 minutes in spring, summer and fall 2026, serving stops including Sieur de Monts, Sand Beach, Thunder Hole, Otter Cliff and Jordan Pond. The last Loop Road bus leaves the visitor center at 4:50 p.m. and Sand Beach at 5:25 p.m. (exploreacadia.com) Acadia is entering the season after a record year. The National Park Service reported 4,079,318 recreation visits in 2025, putting Acadia seventh among U.S. national parks by visitation. (nps.gov) The park has been using timed access and shuttle service because crowding has built for years. Acadia’s reservation page says the park now gets more than 4 million visits a year and that visitation has risen almost 60 percent over the past decade. (nps.gov) Visitors also face several spring restrictions beyond traffic. Carriage roads have been closed since March 19 for mud season, and trails including Precipice, Jordan Cliffs, Penobscot East and Valley Cove are closed for peregrine falcon nesting. (nps.gov) The park’s message for 2026 is narrower than a generic “come early.” If you want Cadillac Mountain, Sand Beach or Jordan Pond on a summer day, Acadia wants that trip mapped out before you reach Mount Desert Island.
