Despite the rain in the morning to Cape Kamui, Allen our nice tour leader informs us (family with 2 kids) that the optional boat ride is running and sea state will be ok. At Otaru, we find perfect weather during boat trip to blue cave. Sea gull feeding is fantastic. Overall day trip is good, bus is clean and looks new, almost full with tourists. The tour operator is very professional, nice, and informative. We start and finish on-time with optional boat trip taken to blue cave. Very recommended. Thank you for today!
