I will be in Haridwar for a day and am thinking that maybe I should travel another 50km ahead and go to Dehradun. I have been there before but have missed out on going to robbers cave which I have just read about recently. I am thinking why not visit the place since people are saying it is good, but before any final moves I wanted to get some honest opinions from members as I don't really trust what people write on blogs as it can be fake and paid for. Please tell me is it worth visiting the robbers cave, and what exactly is it? Is there anything else to do there like boating or you just see the caves and come back?
