I'm always on the lookout for new campgrounds nearby my town. It's nice to have a few places to escape to for a quick day or weekend trip. I searched on thedyrt.com for campgrounds nearby and noticed a group of listings near Lake Travis in an area called Hudson Bend. I decided to check them out.
I visited The Sunsets at Travis RV Park, but discovered that it is not really a RV campground. It is more of a long-term RV park. It seemed that most of the guests were permanent or month to month guests. The park does offer reasonable rates, but there are few amenities. The park is somewhat removed from the lake shore, so if you'd like to visit the lake you'll need to drive to it. There are some trees and open space at the park, but the RV sites are located pretty closely to each other and there are limited opportunities to really explore nature at the park.
I believe that there are better options available. See La Hacienda RV Resort
