From Baker Bay Park, circle Dorena Lake on paved road & bike path This hike can be done in either direction, this discription is clock wise. From Baker Bay park entrance, head west on the highway. You'll pass the road on the Dorena Dam (a nice 1-mile out and back), then drop down the hill past Schwarz Park. After you cross the Row River, take a right onto Row River Road. At the top of the first hill look for the entrance on your left for the Row River Trail. The paved path that follows along the lake and was paved over the railroad right of way. There are several view points along this path and several restrooms. When the trail again crosses Row River Road, take a right onto the road and follow along the river until you meet backup with the highway at the covered bridge. Take a right and head up the hill for about 5 miles back to Baker Bay park. The last part of this hike is along the highway, while there is a wide bike lane, it isn't safe for young kids. This loop is best done on a bike. Hike the Row River Trail
This path is by no means difficult but it is beautiful. There are multiple places to park for free. Dorena lake is pretty big so although I like walking/running I would suggest bringing a bike if you want to get around the whole thing. I just went over the weekend 2/25/17 and a lot of the lake was drained so there were even more areas to explore. Go there if you like well paved paths, beautiful views, and friendly people. Bonus, the lake is great for water sports in the summer.
This was a really good ride except for the fact that about one fourth - one half was on the main road. One side of the lake is all road and the other side is all trail. Everyone we met was super friendly.
So the loop is actually part trail, part road. However you can ride for a good 15 to 20 miles on the bike path if you plan for an out and back trip. The path has some great views and is a pretty smooth ride.
