Hiking options in Niseko are endless, whether you enjoy hiking trails in the summer or you are looking for a bottomless powder experience in the depths of winter. We recently went for a mix of the two, hiking Mt Weiss in the last week of April. Weiss is a smaller mountain to the north west of Mt Annupuri which is home to the Hirafu, Hanazono, Niseko Village and Annupuri ski fields.
