From San Antonio, take US Highway 281 north past Marble Falls to Burnet. Turn west (left) on Highway 29 towasrd Llano. Take Park Road 4 to the south (left). Cacti should be blooming all over if you time it right. Lots of pink granite outcrops here make wonderful contrasting landscapes and closeups. Lots of Whitetail Deer are also in this area, especially on the golf course in the evenings.
Prickly Pear cacti abound in this area of the Llano Uplift and the Texas Hill Country, and usually bloom after the first soaking rain in late April or May.. Blossoms are usually yellow to orange.
