If we need to use the restroom, do we have to walk to the parking area? Or is there some by the pool area.

There is no restroom near the pool. Its located near the parking lot. You need to empty your bladder before you head down to the hills. Bring water with you. Dont worry you will be sweating it out on your way up. Worth every step.

Agree with all prior answers. The only toilet facilities are up near parking.

By the parking area

I think they are closer to the parking area.

I did not see any facilities near the pool.
