if you cant get onto 8a. here is what it says. (small bit of)
Mumbai: Mumbai has a very nice bouldering area and a few sport routes on its outskirts. The rock is basalt and there is some variation in its texture even in the area itself. Grades range from V0 to V8 and from 5b to 7c+ for boulders and sport routes respectively. It will take at least 2-3 days for a very good climber to complete everything around. There is a scope for more problems. The best time to come would be anytime from October to February. Staying is never a problem- just e-mail us.
P.S. You are always welcome at the Girivihar International Climbing Competition, which takes place here in late January! Some climbers of note have already visited it.
if you are there for a while, im sure that you will be able to quest up to the himalaya. close to gongotri there is some fantastic bouldering. but watch out, when i went the village was closed due to heavy snow.
ill try and find the website of a guy who had done loads of bouldering up in the big mountains...
