Four Tree Island is part of Prescott Park and is accessed off of Peirce Island Road via a causeway from Peirce Island.  The island is carry-in, carry-out.  Restroom facilities are open daily in early April to October 31st (weather permitting). Reservations for the Spring/Summer season open on April 1 at 9:00 am each year.

We will begin accepting reservations for the 2023 season on April 1, 2023 at 9:00am.

The Island is a public facility open for all to enjoy.  There are several picnic tables and grills on the island for small and medium sized groups to use without reservation. There are no vehicles allowed on the island. The island is accessed via a gravel causeway that is about 100 yards long. 

In addition, there is a small pavilion with three picnic tables and three grills, which can be reserved through the City of Portsmouth. To make a reservation, call the Recreation Department at 603-427-1547 or visit to create an account and make a reservation online. 

There is no reservation fee, however, the City does encourage donations to the Park (for more information on donations, click here).
