Kedarkantha trek is much open from April. For the snow melts down paving way for the trek. An ideal season which won’t be freezing. May month you could experience the first blow of summer winds, cold is bearable. There are no rains predicted. So you get to see lot of green pastures, blooming mountains. Both months are ideal time to trek in Kedarkantha.
Definitely you can go to kedarkantha treak starting April is fine maybe you can find snow there.not sure in may . it's one of the beautiful treak in Uttrakhand. plan your treak in starting April 🙏
