Visitor Rules

Giving the OLLT properties the care and respect they deserve requires the full participation of all who visit and enjoy them. By following these simple rules you will help us to preserve these lands for generations to come:
No littering — Always carry out what you carry in; please bring a bag for your garbage.
No hunting
No Motorized Vehicles — All Terrain Vehicles. Trails get damaged and pose risks for hikers.
Watch your pet — Keep dogs under your control at all times. Please clean up after them to keep the trails pleasant for people who follow.
Don't wander — Stay on the trails and do not trespass on adjacent properties.
Respect property — Do not camp, start fires, mark trees or collect plants or minerals.

OLLT preserves are open from dawn to dusk. You are welcome to visit any of our properties during daylight hours.

Coyote Alert

Coyotes have been sighted on some of our properties. While wonderful to observe, coyotes have been known to prey on small dogs, particularly during breeding season, so please follow our visitor rules about keeping dogs under control and staying on trails. And please report to us any sightings in our preserves. For more information on safety, refer to Living with Coyotes on the CT DEEP website.
