San Antonio Park is almost ideal for a large star party. The only quality it lacks is altitude. However, it has the best landscape of any star party I've attended this year. The observing field is large, virtually flat and rock-free, and has great horizons from most locations. Surrounding the main observing field are numerous campsites with large shade trees, running water, and picnic tables.
Portable toilets make up in quantity what they lack in quality.
We occupied a small fraction of the campground we were in. There are numerous other open fields nearby and many other campsites. This location could easily hold a star party rivaling the largest in the country. Also, showers, swimming and boating in the lake, and a small store are a short drive away. The park staff was the friendliest and most accommodating I have ever experienced.
