The Thendara Mountain Club is based in a rustic lodge built atop Hasenclever Mountain in the Harriman Section of the Palisades Interstate Park. The original structure, built in 1920, is used for dining, socializing, reading or enjoying a blaze in the fieldstone fireplace.  Our Harriman camp building has a screened-in porch, sleeping rooms and a complete kitchen.  The  TMC “bunkhouse,” a screened sleeping house, adds to the warm weather enjoyment of the camp. Tent sites round out the overnight camping options.

Thendara Mountain Club is operated on a year-round, cooperative basis.  TMC Members volunteer to host a weekend or midweek at the camp. The participants share the work of creating a meal and then enjoying the fruit of their labors. Friendships are formed while working side by side in the kitchen and breaking bread together.

Harriman State Park hiking trails start at our doorstep, and a short walk down the hill leads to Lake Tiorati. Our Harriman Group Camp facilities on Lake Tiorati include canoes, kayaks, sailboats and a swimming area. The winter brings opportunities to hike, showshoe, cross-country ski, or relax by the warm fireplace.
