This midnight-blue crater lake, enclosed by a fuzz of pine trees, lies 5km southwest of Besse off the D978 at an altitude of 1197m. Blasted out of the earth 6900 years ago when rising water met boiling-hot lava, today it attracts trout fishers and walkers. The partially paved trail around the shore takes less than an hour. Winter, when the lake has a frosty halo, is even more beautiful, though the pathways can be treacherous.
There's free parking near the lakeshore restaurant, but at the height of summer it's hard to score a spot. There's a lower parking lot near the D978.
