Easy and flat for riding a bike or for hiking. Ideal in summer to enjoy the shade. In many places there are opportunities to get directly to the lake on narrow paths or to follow the shore over long distances. However - when the weather is nice, at the weekend and during the holiday season (summer) - the area is extremely well visited. This also because of several large campsites!
If you prefer to be almost alone on the road, you can avoid the busy times and enjoy the area. If you have enough time, you can spend a whole day in one and the same spot or visit several places on the water. There are opportunities to grill almost everywhere.
