Parvathi river, Maniharan sahib, chalal, Buddha palace, Shiva mandir and shopping are places to visit in Kasol. Unable to find correct timing of the bus from Kasol to Mandi. Looks like HRTC buses direct are not there. Mandi is 4 hours away from kasol. You could either go by private bus where travel duration might be a bit longer, while cabs, taxis are available too.
