Above the Maiden Falls are the Maiden Pools – the trail goes above the pools, and it requires some off trail walking to get down to them – use your discretion and be aware that walking off trail can permanently damage habitats. Once at the pools, be very cautious of flash flooding possibilities (the only way down is over the falls), and take care not to go near the edge ... it's a long way down. Act responsibly, make good decision, enjoy.

Reaching Seven Falls involves crossing a stream multiple times, which should be done carefully, especially during periods of high water. The reward in seven falls cascades with inviting pools, perfect for a refreshing dip on a warm day. The pools are seasonal, so they won't be full year-round.

Not big enough to swim in, but definitely cool to see! The Maiden pools are a collection of small indentations of sitting water. Depending on the season the entire area can be covered in water, which in my opinion is not as exciting!

Great place to learn about the desert and see native plants and animals. Well worth the annual membership as it is a great place to wander about. A true Tucson gem.

Parking is across the street. No water access at this trailhead.

This "lake" is a popular destination in Sabino Canyon Recreation Area, despite the fact that the reservoir has essentially filled itself in, and the lake is now a creek that spills over the top of the dam. Keep an eye out for a remarkable diversity of plants and animals, especially birds. The trails around the lake itself are reasonably easy, but there is a very tough climb up Saddleback Mountain to the east.
