Park Loop Road
This 27-mile road provides a perfect introduction to the park. You can drive it in an hour, but allow at least half a day so that you can explore the many sites along the way, including Sand Beach, Thunder Hole, and Otter Cliff along the 2-mile section known as Ocean Drive. Park Loop Road is served seasonally by the free Island Explorer buses—and given the summertime crowds, consider hopping on. Traffic is one-way from near the Route 233 entrance to the Stanley Brook Road entrance south of the Jordan Pond House. While most of the road is closed from December through mid-April, Ocean Drive is open to vehicles year-round, as is a small section that provides access to Jordan Pond from Seal Harbor. Off-season, you can still bike and walk on the road; it's also used for winter activities, weather-cooperating.
