Lost Maples State Natural Area: East Trail Professional Review and Guide
"After scrambling for a mile over, around, and up limestone outcroppings deceptively called steps, you can view the Sabinal River and canyon from the canyon’s ridgeline. Descend 400 feet in a quarter-mile over more limestone steps. Complete this rugged hike by making multiple crossings of the shallow Sabinal River, passing huge boulders, springs, plateau grasslands, and wooded slopes.
In spring, you may see the endangered black-capped vireo and golden-cheeked warbler. In October and November the maples display the most awesome fall foliage colors in the state. The park also holds the state’s largest Chinkapin oak and bigtooth maple. The park was named for the stand of isolated, uncommon Uvalde bigtooth maples."
