Surrounding the City of Vancouver water treatment facility is a natural wooded area with trails meandering through out it. In total there is likely a mile of trails. Most of the trails are wide, level and well used, making it easy to wander for some time. This is a great place to stroll through a forest.
There are entrances to the natural area at the corner of SE 102nd Ave and SE 15th St, at the end of SE 98th Ave, and on SE 16th St.
