If you don’t mind the freeway noise, Beaver Marsh is a great place for a walk in the woods. This area sits just west of Interstate 205 with a wide well maintained loop trail as well as a couple looping side trails. Friendly neighbors walk the trail, but also the day I was there some kids decided to lay limbs across the trail to form obstacles.
The main trail crosses Burnt Bridge Creek twice. Once over a nice bridge at the west end of the area, and on the I-205 culvert at the east end.
