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.
