Overview

Moss Lake is a hidden gem of a lake! WTA volunteers are helping King County Parks improve and expand the trail network here.

We'll have fun, work hard and make a difference! No experience is necessary.

Project Description

Our project is focused on new trail construction and trail maintenance. Activities will include new tread, adding drainage features, drainage upkeep, brushing, trail clearing, and rehabilitation.

Note: Please follow the written directions above instead of using a GPS device. This will ensure that you get to the correct meeting location for this work party. The location of the pinpoint below is only approximate.

Getting to WTA work parties can involve travel on rough, unpaved roads in areas without cellular service and without street addresses that can be accurately used by navigation devices. Unless specifically noted otherwise, routes can generally be traveled by all types of vehicles. Volunteers with limited experience driving on unpaved mountain roads may want to allow extra time, beyond what is recommended in the directions above, to get to the meeting location.
