Roads and Parking LotsCadillac Summit Road Closed for ConstructionThe Cadillac Summit Road is closed through April 30 for all uses, including pedestrians and cyclists, from the Park Loop Road to just prior to a parking lot at the summit. Hiking trails to Cadillac Summit remain open. Construction crews with heavy equipment are building a pedestrian walkway to connect the two parking areas at the summit of Cadillac Mountain.
Park Loop Road A section of the Park Loop Road, from the start of one-way traffic to Kebo Street, is closed by construction to all uses effective April 6-14. Since most of the Park Loop Road is already closed to private vehicles for the off season through April 14, this closure further restricts recreational uses, such as walking and cycling.
Park Loop Road Detour A section of the Park Loop Road, from Kebo Street to Sieur de Monts, will be closed to all uses from April 13 to June 12, excluding Memorial Day Weekend. A detour will redirect motorists out to Mount Desert Street and Main Street following Route 3 to re-enter the Park Loop Road at Sieur de Monts.
Cadillac Summit West Parking LotHalf of the spaces in the Cadillac Summit West Parking Lot, also known as Blue Hill Overlook, will be closed for construction from May 1 to June 18.
Carriage RoadsStarting March 19, Acadia's historic carriage roads are closed to all uses until further notice to protect them during spring thaw, also known as “mud season.”
Trails
Jordan Cliffs Trail, Precipice Trail, Penobscot East Trail, and Valley Cove TrailTo provide peregrine falcons adequate space for nesting, the National Park Service will temporarily close areas including Jordan Cliffs Trail, Penobscot East Trail, Precipice Trail, and Valley Cove Trail on March 1 until further notice. In addition, the parking lot for the Precipice Trail will remain closed to vehicles until further notice. These annual closures protect the peregrine falcons from inadvertent human disturbance or harassment during the nesting period.Research has shown that nesting peregrine falcons are particularly vulnerable to human activities, which can disturb the adults and make them less attentive to the eggs or chicks. Human activities near a nesting area can lead to temporary or permanent abandonment of the nest by the adults leaving chicks susceptible to hypothermia, starvation, and predation. Signs at trail heads and trail junctions around the closed areas indicate where public entry is prohibited. Public entry into a closed area is a violation of federal regulations, which is punishable by a fine, imprisonment, or both. The closure area will be actively monitored, and violations will be strictly enforced. The NPS will reopen the closed areas once park resource managers determine it is safe to do so. In 2025, three breeding pairs of peregrine falcons made their homes on Acadia’s cliffs: one near Valley Cove Trail, one near Jordan Cliffs Trail, and one near Precipice Trail. Two chicks from the nest near Precipice Trail survived until they could fly. To learn more about peregrine falcons at Acadia National Park, please visit go.nps.gov/peregrine. 
BeachesSand Beach, Echo Lake Beach, and Lake Wood are monitored weekly for bacteria from June through August. Read more information on the bacteria monitoring program.
Winter Storms January 2024Scientists’ predictions of more frequent extreme weather events as a result of climate change were a reality for Acadia National Park this winter and spring. Sections of the park endured storm damage throughout multiple extreme storms. As the NPS continues to assess storm damage throughout the park, visitors should exercise caution while exploring.
Acadia National Park staff are working to respond to long term impacts from these winter storms. Loading weather forecast... |
