Great hike! Definitely would do it again! Hidden gem! The drive up was a little over grown and muddy. Would not take a van or small car to get up there! Starting off it was good. Got stuck a few times in the mud. About a mile in you’ll get to falls that are split into two. From there you keep on trailing, pass a small creek, up a mountain and you’ll get to a berry field. Definitely picture perfect! Past the berry patch is a Rocky Mountain face. (You could say two) You’ll hear falls off to the right side and there will be a small lake at the bottom of it. (Wasn’t sure how to get to that area). Keep on rock scrambling! We ended up following the river because we couldn’t find the trail after this part. We sat next to a little pond and had lunch. We completely lost the trail at this point. We searched and searched for it but only found goat trails. Will definitely go back up to try to find the lake!
