Acadia in April: what the park service says

In April you can still drive up Cadillac Mountain at Acadia without booking: the park service's vehicle reservations for Cadillac Summit Road start in late May (May 20 in 2026) and run to late October. Once the season starts, each car needs a $6 Recreation.gov reservation, bought online only, with 30 percent of slots released 90 days ahead and the rest two days before. If you are planning a late-May sunrise visit, that 90-day release falls in February.
