2026 Spring Trails Challenge - March 20 - June 21

Join the Napa County Regional Park and Open Space District's annual Spring Trails Challenge and get outside to explore new parks and trails while supporting our work!

Every spring, we host the Spring Trails Challenge to help everyone Go Outside and Play and enjoy our parks. It's the perfect time for exploration here in Napa County with wildflower blooms, green hillsides, and clear days for outstanding views.

We’re celebrating our 20th anniversary this year and have assembled some of our greatest hits for the menu of trails for this year’s challenge – these are some of the most iconic Napa hikes and rides and even if you’ve visited them in the past, are worth the return trip!

See below for details about how to register for the challenge.

Support Your Parks & Trails!

It's easy to love the parks, trails, and natural open spaces we have here in Napa County and we're on a mission to help you find your next favorite adventure through the Trails Challenge. You can also support your favorite parks and trails while you're completing your challenge and raise funds to support NOSD's work and score a limited edition t-shirt in the process!

You don't have to fundraise to participate in the Spring Trails Challenge - but your donations maintain and improve trails and we'd love your help!

How the Spring Trails Challenge Works

The basics of the challenge are simple: select 5 trails from our list of qualifying trails, hit the trail and get photos of yourself out in the parks, and enter to win prizes!

Extra Credit (and very much appreciated): Raise funds to help support our work and improve our parks and trails & qualify to get an official 2026 Spring Trails Challenge T-Shirt!
