yoga/juice retreat (Mumbai)

Can anyone recommend an easy getaway from Mumbai for a few days of a yoga/detox retreat? I am looking for a place where it rains less than Mumbai, is beautiful, is easy to get to even by airplane, and offers yoga and Ayurvedic therapies. A little bit of sightseeing and lot's of nature would be great! I am thinking my best bet is somewhere up north or even in Nepal, but I prefer to go to a recommended place. Thanks so much!
