Flat trails with only one slight incline on the path from the Observatory. The path from the Amphitheater towards the lake has downhill with a beautiful view of the lake. The day we hiked, the Observatory was closed, as were 3 of the other trails. Lots of solitude!!! There were a few red tailed hawks flying above... and 2 armadillos. Would love to see the other trails (closed for the season).
