Diablo East Loop Trail is a 1.7 mile lightly trafficked loop trail located near Del Rio, Texas that features a river and is good for all skill levels. The trail is primarily used for hiking, camping, and birding and is best used from April until May.
I did some trails near the "Quarry" area off hwy 90. It has some decent views, great sunsets and really picturesque desert flora. They are not too strenuous, about 3-5 miles round trip.
