Description
Waypoints (0)

Catalina State Park charges an entrance fee of $7/vehicle. Visitors entering on foot or bicycle are $3. Note: The southern portion of this trail is in the Pusch Ridge Wilderness and is closed January 1 - April 30 annually for desert bighorn lambing season. Dogs are not allowed within the Pusch Ridge Wilderness at any time. This trail is not listed on the park map but it starts at the same trailhead as Romero Ruins. It was a great hike up to the canyon and waterfall. It is a great trail for wildflower viewing in early spring. Once past the falls there are several other paths and it’s easy to make a wrong turn. Once you’ve made the descent with a mile to go the trail is easy to follow. Main washes near entrance are now dry.

I would recommend this hike. I would considerate this a moderate hike. Not because of the climb but the rocks one has to navigate as you climb up and down at the mid point. Loved the saguaro cactus especially once you leave the burn and head down the rocks on the clockwise return.

We hiked the Bridle Trail to the Alamo Loop trail. The beginning portion going clockwise includes a steeper section followed by an area impacted by the 2020 Bighorn fire that impacted parts of Catalina State Park. Even in this area, there are many signs of recovery including new plant growth and bird activity. The 2nd half of the trail wasn’t impacted by the fire & has lots plants, trees and saguaros. In monsoon season, there are several areas that would have running water and a waterfall. I definitely recommend using a map as there are many “shortcuts” and unmarked trails. There are some cairns in spots, but not enough to hike unaided. There are also some spots that are rocky and / or have loose soil that warrant some care and good hiking boots.

It’s a bit more moderate than easy. Definitely use the AllTrails app; many crossovers unmarked.

Don’t follow wash. If u are on it turn around and find trail. Trail is not marked very well

Good hike - saw a lot of desert flowers and a few birds. The trail was not marked at all though, so All Trails was necessary to make sure we stayed on the path

Fun little hike. Not a great deal of elevation change. It barely ranks as moderate, in my opinion. However, it’s a beautiful hike with great views. One thing I would warn against is that it’s very easy to start with one trail or loop in mind and then end up on a completely different path. Pay close attention to your maps. There are many trails going in different directions.

This is an amazing loop even in drought. We did the loop clockwise. In the uphill north stretch we passed through the burned areas from the Big Horn fire which were slowly recovering. There were very few, but still some wildflowers because of the drought. Even a few areas with Mexican gold poppies. The south return loupe had spectacular scenery and was very different from the uphill loop.

I now know why someone wrote “lots of entrances.” We would have been lost if not got our trail app. Zero trail signs, which is tricky when you get into some of the rocky gorge areas. Some of those areas I’d definitely rate moderate, not easy so maybe we did veer off a few times. Some pretty variety of scenery, just know what you are getting into.

Easy loop trail - not crowded today! We added some bushwhacking to go further up into the canyon.

This trail has a beautiful view of the mountain! A few narrow areas and inclines but all and all very enjoyable and pretty easy. Great for adults, children, and dogs!

The west side of the loop that goes along the wash had very little damage from the fire. Still very pretty. The east side of the loop was mostly burned. There were just a few little sections that survived.

Nice hike. Great views. Coming up right after a rain to see the waterfall/rapids canyon at the top.

Great trail. But in the comments when they talk about easy to get off trail they are not lying. We walked at about eight months after the fire and with everything burned down it was especially easy to get off trail. But other than that I will do it again.

Beautiful scenery and super convenient as right in Oro Valley. It was our first hike at Catalina Park. Downside was trail not marked well with lots different choices of which way to turn so had to look at the map app a lot- which is handy tho.

Start at Romero Ruins Trailhead inside Catalina State Park. Go past Romero Ruins Trail. Follow trail to the left, up the stairs. Rocks everywhere, burn area, then Saguaros amongst rock ridges. An overlook next into a deep canyon. Went to the park boundary and turned around.
