This small area of five lakes (go-ko) is the most accessible part of Shiretoko, and thus the most popular. Around Ichi-ko (Lake One), there's an 800m-long (40-minute return) elevated boardwalk protected by an electric fence (to keep bears off, which do appear around here sometimes) on which anyone can stroll.

There's a ground path (adult/child ¥250/100, 1½ hours, 3km) around the other four lakes; however, the number of people that can enter is limited. You'll need to first submit an application at the Shiretoko-go-ko Park Service Centre and, while you're waiting your turn, watch a safety video on bears.
