Rattlesnake Island Preserve (Lake Winnipesaukee, Alton)

Rattlesnake Island is one of the largest islands located on Lake Winnipesaukee. LRCT owns 102 acres of the Island’s interior which is managed as a nature Preserve and includes the Rattlesnake Island Trail to the island summit.

The entire shore frontage of the island is private property. Access to the LRCT property is gained through a ROW that connects the Preserve to our dock on the southeast tip of the island. Our dock is marked with an LRCT sign to help distinguish it from the surrounding private docks.

Public access to our property on Rattlesnake Island is restricted by a Deed Restriction (that was established with the conservation of the LRCT property) that limits access to LRCT members (and their guests) and to only 12 people at any one time. Please display your LRCT membership decal on your boat while visiting. If you aren’t already a member you can become one here.

Island Access

The LRCT shorefront lot is located near the southern tip of the island. There is a small dock with a LRCT sign. Access is limited to 12 LRCT members and guests at one time. There is a 3 hour docking limit.

Please respect private property of our neighbors. Thank you.
