The crew consistently earns praise for their warmth and knowledge, with marine biologists on board who educate guests about whale behavior while maintaining respectful distances. Many reviewers highlight the friendly, attentive staff who provide complimentary non-alcoholic drinks and genuinely care about creating a good experience. The boats themselves get positive marks for stability compared to smaller rafts, which families especially appreciate. Whale sightings vary significantly depending on timing. Peak season visitors in January and February report abundant activity with multiple sightings, while those visiting in December or late April see fewer whales, which is simply the nature of migration patterns. The company does offer a guarantee allowing you to rebook if you don't see whales. A few practical notes: expect a half-kilometer walk from the check-in area to the boat, which can be challenging for those with mobility issues. Some guests mention crowding at the rails during whale sightings, making it harder for shorter people to see. The captain works hard to find whales and navigate to calmer waters when possible, though rough conditions can occasionally affect comfort levels.
Had a great experience, unfortunately we had our trip end of whale season but we had some luck with a couple of whales. Crew was awesome extremely attentive always asking if we needed anything. Will absolutely book this boat again within whale season next time . Only annoying thing was that we weren't warned about the photographer Lady at the beginning of the tour . She's extremely nice but was not warned about the cost of her photos. Had wr known we wouldn't of wasted her time. Recommend you park at the main parking lot where the aquarium is. And PAY FOR PARKING ASAP. they monitor parking quickly not even kidding. Walk into the shopping center and DOWN THE STAIRS. to boss frogs.
