Henry Hagg Lake is part of Scoggins Valley Park in Washington County near Gaston, OR, about 25 miles Southwest of Portland.  The lake was created in 1974 by damming several creeks flowing east of the coastal range that are part of the Tualatin River watershed. The lake helps the agriculture-based economy of Washington County that is dependent on the reservoir and dam to provide irrigation and drinking water as well as flood mitigation services.  The park is day use only and is open all year round, from sunrise to sunset.


After paying the $7 day-use fee to enter the park, turn left over the dam and park at Elks Recreation Area or continue to Boat Ramp C for more field access.  Each spot has restrooms and plenty of space to park.


Twenty-five miles south of Hagg Lake on highway 47 or an hour drive from Portland is McMinnville.  McMinnville is the center of Oregon’s wine country, known for its world-famous Pinot Noirs.  It’s also home to Linfield College, chic shops, and award-winning restaurants.  The rolling green hills are perfect terrain for trail running.





Trail Runs


The Hagg Lake trail is a 13.9-mile trail that circumnavigates the lake.  The trail meanders through trees, sloughs, and stream crossings.  The trail uses some roads as the bridges for the larger creeks and the dam.  In the winter, the trail is known for it’s challenging mud terrain, which makes climbing the rolling hills a test on the body’s core, and the descents a brave battle to stay upright.  The trail dries out in the summer, where mountain bike tire ruts make a different type of technical contest.



Miller Woods is a 130-acre property located 3 miles west of McMinnville.  The trails contain a wide array of ecosystems ranging from hayfield and oak savannah to timber stands.  The Outer Loop Trail is 4.5 miles with several connector trails to get longer distances as needed and rolling hills to make a challenging workout.


Rainbow is a set of trails on Baker Creek Rd. west of McMinnville named after the former Rainbow Lodge.  Mountain bikers combined former logging roads, jeep trails with some new trails to take advantage of the coastal mountain slopes of Slide Mountain.  The trails wind through conifer and deciduous forests.  The occasional clear-cut forest provides views of Mt. Jefferson and Mt. Hood of the Cascade Range. Here’s a great ten-mile route created by Chuck Fisher of MTS-Trail.
