Kasi is one of the mukti kshetram, Bindu Madhava Perumal resides there. One can take a holy bath at the Ganges. There is a temple there for Adikeshava Perumal. There is a Perumal temple at Manikarnika Ghat too. Travelling to Kasi is not wrong but at Kedarnath, there are temples for Lord Shiva only so there is no need to visit them.
