Buck Lake is a small lake that was once part of the main Llano River, but got cut off during a large flood event. This trail will take park visitors to the lake and around it. There are some sections of this trail that are shaded, but much of it is exposed to the hot Texas sun.
The trail begins in the main campground, which is quite convenient for campers. After only a tenth of a mile, you'll pass the Acorn Blind, a spot to watch birds without them noticing you. North of the blind is a field that the blind observes. The trail passes along the western edge of the field and then turns east to cross the top of the field. At a fork, the trail loops north around a second smaller lake before turning west (taking the fork straight/east would bring you to the River Trail
). You'll finally come to nice lake views that are enhanced by a small pier. At the northwestern corner of the lake you'll meet a spur to Inner River Trail
. The trail turns back south to close the loop on the west side of the lake/field. You can take the trail back past Acorn Blind, or follow it west to the park road.
