Happy River Points
The lower put in is at Halfway Lake and has a bit more volume at this point and the run to the Swentna River is 27 miles of continuous rocky rapids of Class III to III+. A Cessna 206 or DeHaviland Beaver on floats is available from Susitna Air Service at Kashwitna Lake and likely from other Willow and Talkeetna based flight operators.
