On National Public Lands Day, the Hill Country Conservancy will host their seventh annual Violet Crown Trail Fun Run, a 3-mile fun run along the Violet Crown Trail, kicking off at Whirlpool Patio. There will be a finish line party with refreshments, an opportunity to learn about the Edwards Aquifer and Whirlpool Cave, and a chance to meet some community partners who support the Violet Crown Trail, outdoor education, and the native Hill Country wildlife.
