Welcome to
Thendara Mountain Club

Who We Are

Thendara is a non-profit social club whose members enjoy hiking, boating, swimming, and maintaining trails in Harriman State Park. 

Our 100-year-old rustic lodge offers a base camp for year-round activities and social events. Weekends are typically hosted, with all meals provided and chores divided. Participants can stay overnight in the lodge or camp out. 

Harriman State Park hiking trails start at our doorstep, and a short walk down the hill leads to Lake Tiorati, where we maintain a swim dock, boat dock, and a boathouse stocked with kayaks, PFDs, and other gear.

    Join Kathy Haake and Hector Cruz for a late summer weekend to have fun in the sun. You can enjoy the lake with some swimming, canoeing, kayaking, hiking or just do some relaxing.

    Start the weekend with a happy hour followed by a pasta meal and dessert. Let's relax by a campfire to end the evening. Wake up to breakfast and a trail lunch ending the weekend enjoying the lake or the hiking trails.
