Nice hike with well marked trail.
Parking is a PIA. The Adk Log parking is very popular so we parked about 1 mile up the road and walked to trail head inAdk Loj basecamp.
Pretty easy trail with minimal climbing. Took us 1 hr 40 min to get to Dam. Another 1.5 to get back. We are not routine hikers so if you are you could easily make much better time.
