It’s about two hours of sweat in the trees, but once you really start climbing - that little half mile stretch of a thousand feet in the middle isn’t the climb - this becomes an exhilarating hike. Summit Loop isn’t as maintained as the lower part because of less traffic. Be ready for a bit of scrambling. Went up on 17 Aug and had no issues with bugs. Still hazy and could only see the closest mountains. Bring hiking poles and at least 2 quarts of water. Not for the weak or faint hearted.
