This is an amazing spot for a family trip. We stayed in February 2021 for 6 nights in site 13 on the RV Loop. Access to the lake from the site (short walk), wooded area that blocks the wind but you get sun during the day. It was completely full on the weekend days (in February) but almost empty weekdays.
The resort is beautiful, we only walked up once to check it out but they have a lookout area and restaurant and bar (limited hours during off season) but beautiful patios with fire pits and sitting areas to watch the sunset over lake Buchanan. Small camp shop was open, pricey ($12 for 3 pieces of campfire wood), but I get it pay more if you don’t want to drive the 30 minutes to the closest place.
Beautiful trails that are easy to walk and bike for all ages. We got to see some wildlife (deer, armadillo, raccoon, etc).
I would definitely return if we came back this way.
