This is a very beautiful hike that leads to a really nice set of falls and pools.
To enter the Catalina State Park costs $7 per vehicle with up to four adults. You then drive to the trailhead parking lot. There will be a restroom and a very small shop there. From the trailhead, you almost immediately crosse Sutherland Wash, which flows seasonally. The first 1.1 miles is relatively flat and an easy walk (up to the end of this point, no dogs are allowed). The next 1.7 miles are a steep and rocky climb to Romero Pools. This part might be a little difficult for beginners, but still worth it once you get to the pools. It takes most people at least an hour and a half to get there and about the same to get back. This is a hike with a very beautiful view and definitely worth doing. The water at the pools is usually very cold, which can be really nice on a hot day.
During the summer time be sure to watch out for rattle snakes!
