The lower (south) portion of this big park is thick forest along Lacamas Creek. It's a surprisingly fun mountain biking area with medium difficulty and lots of hills.
The north side of the area is Round Lake and Lacamas Lake with a pretty trail along both.

East of Vancouver is Round Lake and Lacamas Park. This park is remarkably scenic, with thick forest, a lake, a river, and hiking and biking paths all through it.
