We were actually looking for Green Line #6 trail, but couldn't find it (again). Ended up parking on the road and hopped on the Mima Falls Trail West somewhere in the middle. Went off-trail as soon as we hit the river, and immediately found a really cool beaver damn (it was huge). Lots of signs of recent beaver activity, but didn't see the beavers :0(
Took a left at the loop sign to the camp, but didn't have time to do the whole loop. From Lost Valley Trail, we hit the road and couldn't find the rest of the trail. We went quite far down the road in BOTH directions, but gave up and started back down. Had lunch back at the beaver damn, hoping to find the critters, but no such luck.
