Starting March 2, hikers will be required to pay a $10 fee per person and animal to use the River Place Nature Trail. According to the River Place Limited District's website, children 12 and under with an adult and residents with residential IDs may hike for free. Only credit card payments will be accepted—no cash. Staff will be at the trailheads collecting the payments. Currently they will be there on weekends only, a River Place representative said, adding the fee was put in place to limit trail traffic and help with upkeep costs. The River Place Nature Trail Canyon Trailhead is located at 4998 River Place Blvd., Austin. 512-246-0498. www.riverplacelimiteddistrict.org
