Took just under 3 hours with lots of pics and a brief stop at the top. Climb to the highest peak in the Tucson Mountain. Nestled in Arizona's Catalina State Park, just north of Tuscon, are the Romero Pools. If its the only option, of course, go for it! Windows create a light filled interior with well placed neutral accents. It took us two and a half hours for the out and back to the Romero pools.
