Very enjoyable state park; great for a weekend getaway with plenty of great options for tromping through the woods. The campsites are wonderful, with plenty of flat areas, not a ton of sharp rocks, and some pretty awesome fire pit/grills. (Just be aware that the "Campsites with water" are closer to the restrooms, but they're also quite close to the road, so you'll definitely get some traffic noise at night.)
There's about 5 miles of charming, meandering, well-shaded trails, so the whole park is easily doable in a weekend, and there's plenty of varied terrain which keeps things interesting. Everything from expansive, skeletal cedar woods to swampy, cool lowlands, to claustrophobic, jungle-like trails blanketed in grape vines and brambles. They're all well-tended, well-marked, and quite easy to navigate. This is the northernmost edge of the true Hill Country, so there's plenty of change in elevation, too. There are some real gems hidden here - some very, very cool stuff.
Quick note: If you decide to take the Bosque Trail all the way around the lake, there's a spot at the northern tip where you have to cross the stream, and there's no bridge or stepping stones, so be prepared to go wading. The park site says the stream is often dry, but it was halfway up our shins with all the recent rain. Fortunately there was a convenient gravelly spot nearby where we could put our shoes back on, and the midday dip in the cool stream was a pleasant break from a full day in hiking boots. The Bosque also crosses right over the spillway, so waterproof shoes are your friends. We saw rabbits, deer, various birds, including a vulture and a cardinal (sorry, not a bird watcher), plenty of turtles and perch in the water, and evidence of a beaver.
This is definitely a popular spot for the locals to come fishing, and the banks are well-populated during the day with families coming out try their luck with the stocked lake. The only drawback is that there isn't a designated swimming area, so if you decide to go swimming, just be aware that you may end up dealing with other visitors' lost fishhooks in your toes. read more
