Try Kanatal, won't recommend Rishikesh as it's too crowded these days. from Kanatal you can also go to Tehri lake for adventure sports.
it's perfect weekend getaway
You can try Mcleodganj along with that cover dalhousie and dharamshala.
Or else you can also try Rishikesh and along with it you can visit lansdowne or auli.
