Shiretoko Traverse information
The classic traverse is a two-day hike that stretches for 25km from Iwaobetsu Onsen (岩尾別温泉) to Kamuiwakka-yu-no-taki (カムイワッカ湯の滝). You'll need to be properly equipped to tackle this route. You'll climb Rausu-dake (羅臼岳; 1660m), traverse along the tops to Iō-zan (硫黄山; 1563m), then descend to Kamuiwakka--yu-no-taki, a 'waterfall onsen'.
There are four camping areas along the top that have steel food bins (think bears!). Don't underestimate the difficulty of the terrain. The last bit of this track has recently been reopened. Whatever you do, make sure you drop in at the Shiretoko Nature Centre for the latest on conditions and advise them of your intentions.
