This is a perfect and easy winter hike but of course also for summer. You have the most impressive views of the mountain range Churfirsten and to the valley where you can see the Walensee.
How to get there: Take the cable car up from Unterwasser up to Chäserrugg Summit. You have to change at Iltios which is also worth a break for a winter hike through the forest. But the most popular and easy hike is the Rosenboden Circular Route. it takes 1.5 to 2 hours  and is 3km. 
Price: Its 58chf return on a regular base or 29chf with the half fare/swiss travel pass.
