Lacamas Lake Regional Park includes nearly 13 miles of trails. There is a loop trail around Round Lake, and trails down Lacamas Creek. The trails here are pretty thoroughly mapped in Google Maps, and in the TrailForks App.
In addition to the trailhead at Round Lake (which often fills up), there are starting points at St. Thomas Aquinas Catholic Church at the Trailhead on 3rd Ave, at Woodburn Elementary, and at Lacamas Lake Kayaks.
There has been a lot of new construction happening on the north side of the park, making the hike a little less peaceful, and potentially changing some of the trail connections.
Overall this is a great area to explore, with lots of new trails to find on each trip, and some interesting creek side views.
A short distance to the west on Lake Road is the Lacamas Lake Lodge, Lacamas Lake Park, boat launch and Heritage Trail trailhead.
A short trip down Everett Street takes you to Fallen Leaf Lake Park.
