Hike, jog, cross-country ski or just meander along almost 60 miles of trails through Regional Water Authority watershed lands. Nature’s wonderland is waiting to be discovered on any part of the Water Authority’s network of trails. All it takes is a Regional Water Authority Recreation Permit. As a permit holder, you can enjoy the convenience of free parking and easy-to-read trail maps. We also have areas with special design features for access by people with disabilities. Plus, we’ll invite you to guided nature walks, our annual kids fishing derby and other special events which are only open to our permit holders. Permits range in cost from $20 for a one-year Individual Permit for seniors, the disabled, veterans or students to $50 for a two-year Family Permit.
