the campsite is good for equestrians. if you're a kayaker you can put in here and travel down and take out elsewhere. the lower Colorado River Authority has plenty of places along the Colorado to facilitate this. we stayed here for 4 days before Memorial Day weekend and it was hot. there are no showers or bath houses. there are Porta-Johns located throughout the campground. Texas in summer can be unforgiving. Lake Travis is home to boaters and Jet skiers. there are fish if you're into that.
Shaffer Bend Rec. Area has a beautiful setting in the Texas Hill Country right off of Lake Travis. At the gate entrance you have wonderful landscape views. All of the camp sites are situated next to or a short walk to the water.
The camps are clean. Most are equipped with a picnic table and fire ring. In the large camp area, some have BBQ pits with a couple big communal grill/smoker. The same area has a horse pen as well if you're an equestrian enthusiast on top of a camper. It is a primitive campground. The large camp area has a couple port-a-poties. At the gate entrance there are men's and women's rooms with running water. That's about 3 miles from the camp sites. So, be prepared to dig holes, bring your own portable toilets, or hold it.
Considering you're on the lake, the water access is surprisingly limited. There are a few areas along the water you can walk in, but there's not a dock or boat access. I recommend sandals or water shoes since there's a fair amount of plant life along the shore. The same areas you can walk in would be good for kayaks though. The camp sites are situated along a narrow section of the lake. So, there would be plenty to explore.
