There are various hiking possibilities from First. Some of the routes lead to other mountain tops or bus stations, but you may want to do an easy trip leading back to First. Walking to the Bachsee (or Bachalpsee) is a good choice.
This small mountain lake is situated on the foot of the Faulhorn. Even in summer, there may be ice floating on the lake. Your way towards the lake starts with an ascent, but the remaining part is pretty easy because of the wide and even path. You can rest near the lake and enjoy the great view of several peaks such as the Schreckhorn.
The Bachsee is popular and therefore visited by many people. One of the reasons is that this path offers the passage to one of the most popular hiking routes in the Bernese Oberland: the one from First to Schynige Platte.
