Utoro (Western side of Shiretoko)
The Utoro side of Shiretoko is best visited in the summer and fall. The Utoro Michi-no-eki acts as the nature center, so go there for information on the park. Similar to Mt Fuji, Shiretoko National Park has a famous 5 lake trail called the Five Lakes. There are nature tours through the five lakes, and in the fall there are tours viewing the sockeye salmon coming upstream to spawn. During peak bear season people are required to listen to a short lesson on bear safety before venturing into the five lakes. You can see more bears and Sockeye salmon on the Utoro side of Shiretoko. Because there are so few roads through the park, boat tours are available to see bears on the coast.
Rausu (Eastern side of Shiretoko)
Rausu is visited most often in the winter for its drift ice and the Steller's sea eagles, but you can also visit in summer to see killer whales. There are boat tours for killer whales, Steller’s sea eagles, and drift ice. If you want to see one of the largest and rarest owls in the world you can do that here. At the hostel Washi no Yado you can see 1-2 wild Blakiston's fish owls. They are fed fish every night in the river, so they come to feed almost every night. There are views of these wonderful birds from the window of your room. Located next to the hostel is a special building where people gather to enjoy and take pictures of these owls.
