"You never know what you'll stumble upon in Colorado Bend State Park, which is known for its caves, springs, and sinkholes set amongst a lush, wooded landscape. The park is an easy two-hour drive from Austin and has a good selection of campsites, including hike-in options, spots that can accommodate RVs, and group sites. Just keep in mind that Colorado Bend brands their overnight offerings as 'back-to-nature camping,' so make sure you pack along everything you need for the night — for example, their 'hike-in' sites don't have water or bathrooms." - Travel + Leisure Editors
