Join Docent Tom Batley as he guides you on a less-traveled trail that takes you by Union Creek, to the Sempervirens Falls and back through the redwoods. This is a four-mile, 3.5-hour hike. Bring water and good hiking shoes. In case of rain, Tom will lead a hike up beautiful, and paved, North Escape Road. Meet at Park Headquarters, located 9 miles north of Boulder Creek on Highway 236. Event is free; vehicle day-use pass is $10.
