The Kenai Canoe Trails are divided into two systems, the Swan Lake and Swanson River Canoe Routes. The Swan Lake System is perhaps the most visited of the two systems and contains 30 lakes linked with the main branch and the West Fork of the Moose River in an interconnecting system of waterways and portages. This forms a canoe route of about 60 miles, though many shorter excursions are possible and even likely. Records over the last few years show that approximately 4,200 canoeists paddle some part of this system each year. A little over 40% of all canoeists that enter either the Swan Lake or Swanson River Routes enter the West Entrance of the Swan Lake Route, travel as far as Trout and Gavia Lakes, then return to the West Entrance. About a quarter of all paddlers enter by this same West Entrance and exit from Swan Lake to the Moose River and leave the Swan Lake System where the Moose joins the Kenai River.
