These trails are all pretty easy and short, so this is the ideal place to go hiking if you want to combine it with a day out in the Hill Country. There are some nice views of Lake Travis, but unfortunately most of these views include 1431. You can also hear traffic noise from 1431 on all parts of the trail, which takes away from the feeling of solitude.
Bring binoculars because the Sunset Observation Deck has some nice views that are enhanced by binoculars.
Dogs are not allowed on these trails (it is part of a wildlife reserve), but I still saw people walking their dogs along the trail. I don't know if this is the usual for this place because this was my first time here.
I will return to do these trails again. Cactus Rocks Trail is a self-guided interpretive trail, but all brochures were gone when I got there so I was not able to read about what the markers were pointing out.
