Yes, the Hampta pass trek is a safe trek as no accidents are reported till now. Apart from this, there are slight rains that make trekking a little difficult but is doable. In the winter months, the trek is not safe as it is covered with deep snow and the routes are all blocked. Also, this is a safe trek for solo travelers as the routes are well-defined and you need not worry about avalanches or any other harm from the wildlife.
