Leave Dehradun by about 9 AM. The taxi goes up through Mussoorie and Dhanaulti, roughly 3 hours with stops.
Stop at Dhanaulti Eco Park for a walk in the deodar forest, then on to Kanatal to check in.
Sunset over the valley, then a bonfire at your stay. Mid-November nights get close to freezing, so bring a proper jacket.
Go early to Kaddukhal (40–50 min by taxi) and take the ropeway up to Surkanda Devi Temple, about 10 minutes. Return tickets are roughly ₹180–225; check the hours at the counter. Clear November mornings give the best Himalayan views.
An easy guided walk in Kodia Forest, the oak and rhododendron woods near Kanatal.
A slow evening, and stargazing if the sky is clear.
Breakfast with the view and check out.
Drive via Chamba to Tehri Lake at Koti Colony (roughly 1.5 hrs) for a boat ride or water sports.
Head down to Dehradun or Rishikesh, about 3–4 hours. Leave by 2 PM so you're off the hill roads before dark.
