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.

I would describe it more as a park than a museum. Not exactly cheap, but very nice. Bring your time and walk around and look at everything in peace! It's better to avoid lunchtime in summer! But you can always cool off in the rooms every now and then ;-)

The Cactus Wren Trail is a 3.9-mile loop in the western part of Saguaro National Park. You will stroll along the majestic Saguaro cacti that grow from Mexico to the north side of the Salt River. These cacti are often used as by woodpeckers for nesting, so keep your eyes peeled for some holes in the trunk and it takes roughly a decade for a Saguaro cactus to grow one arm.

Look carefully at the canyon walls and rock formations as you walk along King Canyon Trail. You will see a number of petroglyphs etched into the rock surface. Most of the rock etchings found in Saguaro National Park were created by the Hohokam peoples. Do not touch the petroglyphs as oil from your skin can damage/break them down faster.
