If you use the wilderness parks for hiking, biking, photography or just relaxing, Trail Work might be right up your alley! Get up close and personal with the trails you use; you’ll see them in a whole new way. No experience necessary. This is FUN hard work. Whatever your skill level is, there is a job to do: clearing drains to get the water off of the trail, pruning vegetation back to keep users on the trail, moving dirt to rebuild eroded tread, and restoring impacted areas are just some of the tasks we will accomplish. We will be using tools such as loppers, picks, shovels, and McLeods to improve the user experience, protect the fragile habitat and increase the sustainability of our trails. Expect to hike up to 4 miles while carrying tools. Gloves and tools provided.
