Falcon is a great place for rv camping, birding, and though the lake is low...people seem to be fishing. The roads are free of pot-holes and pavement damage that many campgrounds are riddled with. The hookups are clean and in good repair, sites level. Trails for hiking are not extensive, a 2-3 mile loop with a few side trails. You can cover them in a few hours, but the bird feeding stations, blinds, butterfly garden make each hike quite different in the wildlife you might see. Great area for older kids/teens who might enjoy exploring something bigger than a playground, but not such a big place they could get truly lost.
Restrooms were clean with hot water, leashed-dog friendly. The picnic areas for day use are very nice, many have water. It is obvious they are not right on the lake anymore due to falling water levels, but still very scenic. There is not a playground to my knowledge, but the rec center has a library of sorts with books to loan and reference materials on the local flora and fauna. I believe they have coffee and pastries on occasion.
Park personnel are friendly and informative. All my time at Texas state parks has been great.
