Whoops we lost it!
The Piedra Lisa Trail/La Luz Trail link can be reached from the parking area that leads to La Luz or the Piedra Lisa Trail access. It is a 1/2 mile trail connecting the 2 major trails in Juan Tabo Canyon. We didn't even know it was an actual trail, and lost the trail by following the small stream and waterfalls. So this is the link to show the ACTUAL trail:
