There are maximum 10-15 huge steps at the temple. You may climb it with little assistance. The walk of the temple is not that tough. Distance from entrance to the main temple is approximately 5 minutes. And it is surrounded by huge trees making the walk comfortable as it gives good shade

The best places or must visit places are: 1. Hidimba Devi Temple 2. Solang Valley (Half day to full day) 3. Rohtang Pass (Provided it is open, since it remains closed till May) (full day tour) 4. Vashistha Muni Temple 6. Manali market area.

a mixture of snow and Rain, please prepare accordingly

I prefer old Manali to new. Though if you want some conventional "luxury" might be there. Too hectic and peopled for me. Along the winding uphill walk of old Manali one finds a laid back market that caters to westerners and Indians alike. Cafes, river seating, coffee and craft stores. Up the hill are numerous options towards the town and beyond; many lovely places nestled in the hills with great gardens and views of the mountains. you feel a part of the neighborhood...

Yes if u wish to visit rohtash pass and solang valley. Otherwise a light jacket is fine for town and local sightseeing.

yes u can .. bt try to go on july 1st week

Hadimba Devi Temple is situated on the foot hills of himalayas,also Manali is gateway of Ladakh. This route is open from June till September so most of the tourists come during this period. However if you come to visit particular in Manali so I would recommend April to June as this summer period in North India so most of the Indian tourists come in these months. Temperature goes at day time 15-18 degree and at night less than 10 degree.

yes

U can travel thru HRTC,it will take 8-9 hours,main problem is that the place where they stop for eating are generally not good.
