Leave the roads; take the trails.

Our Mission

The Old Lyme Land Trust is a non-profit organization dedicated to conserving Old Lyme’s natural, scenic and historic land and water resources for the benefit of the public now and for generations to come. The Trust accomplishes its purpose by acquiring land through donation and purchase, managing the land and by providing education to the public.

Undeveloped land makes Old Lyme unique and beautiful, and it enriches the lives of Old Lyme’s residents. It is a priceless gift to pass on to future generations. Our lands are stewarded by a dedicated group of volunteers who maintain the trails, and a board of trustees that oversees the day to day operations of the trust. We welcome you to visit any of our 14 preserves and use them in accordance with the posted rules.

Hike 'Em All!

There are over 800 acres to explore on our 14 preserves. Challenge yourself to experience them all in 2024 and use this simple Preserve Tracker to make note of when you visit each preserve and what you noticed. Want to send us more feedback? Fill out our Hike 'Em All Report.


Some of the preserves are larger and can take over an hour to hike while others are smaller and offer a great way to indulge in a quick nature break in the midst of a busy day. Keep in mind some trails are more challenging than others and may not be suitable for all hikers. Read preserve descriptions, access trail maps and Choose your next hike HERE

Please consider joining OLLT as a member and supporting trail upkeep with your donation.  Volunteers are also needed to perform trail work.  Thank you!
