Signal Hill Trail
You are the latest in a long line of people
to pass through this special area. For more than
10,000 years the Tucson Basin has been visted
by many people. As you explore this quarter mile trail, discover why these desert mountains
attracted so many earlier visitors.
For your safety: Beware of prickly plants,
poisonous rattlesnakes, scorpions, and Gila
monsters. Avoid putting hands or feet under
rocks or in hidden plants. Always look before
you step. Stay on the trail.
Trail length: 1/2 mile roundtrip.
