While the camp spots are few, this area gets extra points for its walking/running/biking trails. The park is open 365 days of the year and is first-come, first-serve on sites. Only $10 for the night. Check out the Lakeside Icehouse for events and live music throughout the year. Now the trails: ~20 miles through the trees with well-marked signs to guide you. Maps can be found here: https://brazosvalleymountainbikeassociation.wordpress.com/lake-bryan-trail-maps. Several local triathletes train in open water here as well. Outside of peak concert/event times, this is an ideal area for a quiet getaway.
