The East Side of Mount Desert Island is the busy core of Acadia National Park. It contains the 27-mile Park Loop Road and the most famous spots.
Most visitors start their trip on the East Side. This area features the highest peak on the U.S. eastern seaboard and miles of rocky coastline. Parking fills quickly in summer, so consider riding the free propane-powered Island Explorer bus.
You need a $35 vehicle pass to enter this section. Starting in 2026, non-U.S. residents aged 16 and older pay an additional $100 surcharge.
1-2 hours$6 reservation required
The highest peak on the U.S. Eastern Seaboard stands at 1,530 feet (466 meters). It is the first place to see the sunrise in the United States during winter. Driving the summit road requires a $6 vehicle reservation from late May to late October (May 20–October 25 in 2026). Book well in advance because slots sell out fast.
1-3 hoursOcean Path access
This 290-yard-long beach sits between granite mountains and the rocky shore. The ocean water here rarely gets warmer than 55°F (13°C). It serves as an excellent starting point for coastal walks like the Ocean Path.
30 minsBest 1-2 hours before high tide
This small shoreline cave creates a loud boom and high water splash. Incoming waves compress trapped air inside the rocks to cause the effect. Arrive 1-2 hours before high tide for the best chance to hear the sound.
2 hoursPerimeter path
A pristine glacier-formed tarn sits surrounded by mountains. Visitors often walk the highly popular perimeter path. Stop at the Jordan Pond House afterward to try their famous popovers and tea.
