Lime Kiln Loop

The Spring Lake Natural Area has 12 different trail systems and three different trailheads from which to choose. This particular route starts at the Lime Kiln Road Trailhead, and it uses the Blue Heron Trail, Exogyra, Blue Stem, and Buckeye back to Blue Heron to complete this particular loop. From the trailhead, head south on Blue Heron Trail before connecting to Exogyra by taking a left at the fork. Follow this south to Wickiups and take a left up to the viewpoint. On the way back down, take a left to head to Blue Stem. Follow this north past the junction with Sink Link and at the junction with Buckeye take a right. Follow Buckeye east until you reach Blue Heron Trail and follow this left back to the trailhead.There are plenty of wonderful hill country views along this route, and even a pond where you can pause and enjoy the silence. Some of the trails here have rocks and tree roots, so it may be tricky for little kids.There are various signs along the way if you didn't bring a map, and other signs that showcase various sightseeing focuses in the area.

According the SM Greenbelt Alliance website, the Spring Lake Natural area consists of 251 acres of parkland (making it the second biggest park area in San Marcos) just above the San Marcos River. This area supports five endangered species as well. I recommend visiting the website to learn all of the great history San Marcos parks have to offer!
