In reply to adamki: I think he means £300 pcm all in (food, drinks, accommodation, travel, etc.) but still seems expensive esp. if you rent by the month.
By February/March the hills in the north are warming up nicely (chilly nights though). I saw some nice bits of rock at Triund above Macleod Ganj this Easter - they also have an outside climbing wall at the Himalayan Mountaineering Institute http://www.himalayanmountaineeringinstitute.com/Training_Facilities.htm - which I couldn't use due to recovering from a pulley rupture.
You could contact the HMI about good places for bouldering; the main office is in Darjeeling, also a nice place.
I have heard several reports about bouldering near Manali but wasn't into climbing when I went there 20 years ago.
In reply to Blue Straggler: it IS possible to stay cheaper, but it all depends how you do it. Crucially, if you want to stay in the most popular climbing guesthouses or at least nearby (which, for me, makes for an infinitely better experience), then the average costs are as follows, NB this time of year are peak prices, but I don't it goes down much, if at all, until end of Feb, which is also when it gets really hot:
Cheapest accom = 100 rupees a night (a mattress and mosquito net on the roof of Goan Corner guesthouse), basic hut 300 per night
x 30 = 3000 to 9000 pcm = 35 to 102 pounds a month
3 x meals a day at 300 rupees a day = 100 pounds a month
So maybe I did overestimate things a little, but it's not uncommon to treat yourself to the odd coke, wi-fi sesh or whatever, so giving yourself (quite a generous) extra 100 rupees a day that's an extra 35 pounds a month, grand total around 237 pounds a month. If you're doing 300 quid a month then you're treating yourself quite alot. Most climbers are pretty frugal so, like me, you can probably expect to spend around 200 quid a month here. Very cheap! Hope that was useful for people (and it's helped me to clarify things because it's the first time I've properly worked it out!).
In reply to Andy S: There is plenty of bouldering and routes to keep you occupied around Manali. Some of it is walkable from Manali or Vashist but most of it is a short bus journey/bike ride. The bus only set us back 10Rs (2 years ago) and that was on the rare occasion that they actually remembered to charge us. There are a few local climbing/mountaineering shops who will be happy to point you in the right direction and you'll probably find some other climbers around Vashist.
I found Manali to be marginally cheaper than Hampi as long as you stay away from the ripoff rickshaw drivers (you really don't need a rickshaw there anyway) and the temperature made for much better climbing than Hampi but then I was in Hampi in May so you only got a couple of hours after dawn before it got too hot and sweaty.
