Please note: The Thacher Island Association is dedicated to the historic preservation and operation of Thacher and Straitsmouth Islands, and making them available for the public to explore and enjoy. However, the safety of our visitors, members and volunteers is our top priority. We have made the difficult decision to close the islands to visitors for the summer of 2020 to help slow the spread of COVID-19 for the health and well-being of our community. Please enjoy the videos and historic photographs on our website. We look forward to welcoming you to the islands in 2021.

Thacher Island and Straitsmouth Island are both accessed by ramps which may only be used by the Thacher launch, a dinghy or kayaks. NOTE: For the summer of 2020, kayaks will not be allowed to land on either island and visitors are not allowed.

The distance to Thacher Island from Rockport Harbor is about 3 miles and the Association asks kayakers to use caution, pay attention to weather conditions, and turn back if you feel uncomfortable. It is not a simple paddle for novice kayakers or those with limited endurance. Straitsmouth Island is closer to shore but kayakers must beware of rocks when approaching the ramp at low tide.

Groups larger than 5 boats must call the keepers in advance with their expected arrival time. A $5 landing fee is required for each person arriving by kayak. The island closes to the public at 5pm.

Neither Thacher Island nor Straitsmouth Island has a dock. Access to both islands is only available by ramp. NOTE: For the summer of 2020, no kayaks or dinghies will be allowed to land on either island and visitors are not allowed.

Thacher Island has 3 guest moorings adjacent to the ramp, about 50 yards offshore. You must call the keeper on the island in advance at 508-284-0144 to tell him you are coming. Moorings are free on a first come, first served basis. 

Straitsmouth Island has no moorings, but normally allows dinghies to land on the ramp. Boaters must move their dinghies off the ramp to the adjacent shoreline once they land.

Landing fees of $5 per person apply.

Climbing Thacher Island Twin Towers

The Thacher Island towers are identical and were completed in 1861. They are each 124 feet high, with 156 steps to the top, and stand about 164 feet above the waterline. Each tower is 22 feet in diameter at the base and narrows to 13 feet at the lantern room. They are constructed of solid granite on the outside with a two-foot thick inner wall of brick. Each block of granite weighs over 10 tons.

From the tower one is able to see the skyline of Boston to the south, and the mountains of Maine to the northwest. Looking down to the southeast about a half mile offshore you may see an iron pole jutting out from the water. This marks an area called the “Londoner” so named because of the reef just below the surface which has claimed hundreds of vessels, most bound to Boston from London in the early 1700s. This reef was one of the reasons the original twin towers were built by the British of Massachusetts Bay Colony in 1771. The other reason was to be able to differentiate Cape Ann Light Station from Boston Light to the south and Portsmouth Light to the north.

Camping - closed for summer 2020

Thacher Island has a small campground. Due to COVID-19, the campground will be closed to visitors for the summer of 2020.

If the campground is open, a donation of $5 per night per person is required, along with a landing fee of $5 per person. Payments may be made by cash, check (made out to the Town of Rockport) or credit card and given to the keeper on duty in the boathouse. You must reserve ahead of time by calling the resident keeper at (508) 284-0144.

Camping is basic: without water, fireplaces or electricity. Open fires are prohibited and campers must bring their own water. The site has an environmentally-friendly solar-powered composting toilet and picnic tables, as well as a large covered pavilion to provide campers with sun and rain protection. No pets are allowed.
