It winds along the hillside over a ridge to the pools. You can continue up the canyon past the pools but most people stop at the pools.
Diving into the pools is possible I heard a significant splash while at the pools.
This a relatively popular trail.
As with all desert hikes bring water, 4 litres is the suggested amount. Beware of long skinny creatures.
From Tucson follow Oracle Road north to Catalina park. Drive to parking lot at very end of paved road. You will find a sign for the trail head.
