Pros:
Feel "lost in time" in what appears to be an original growth forest. Lots of elevation and wide variety of shots. Don't need a "huge" arm.
If you are traveling through Juneau on the Ferry, it is a great place to check out. Just hike out or thumb a ride, not far "out the road".
Cons:
Slippery and somewhat rough terrain.
Other Thoughts:
Definitely in my top 5.
You can tell this course has been loved by the folks who made it happen. Also, when I was there I made some instant friends who gave me a ride to the airport to boot. Noonan!
