This bit of river is certainly not for the novice. The first three miles from the put-in is filled with class IV rapids requiring advanced skills and an appropriate amount of scouting particularly as you approach the Loon Mountain Rapids; pull out above Loon Mountain Bridge, visible by mile 2.4. Beyond Loon Mountain the river becomes even more technical for over a mile. At river mile 4 there is a portage on river left over an old dam. After passing through North Woodstock the waters mellow from class III to II+ providing a “mellow” run-out for the final four miles into Woodstock.
