The tour is in two parts. The first is on a large tour boat around the harbor area, and out where the small, white beluga whales feed and play with their young. The boat drops a microphone into the water so passengers can hear the whales talking to each other with their whistling and growling sounds. The passengers are put ashore at the park, an imposing stone edifice at the mouth of the Churchill River, built by the British for protection against the French, who didn't bother showing up.

Due to the possibility of having polar bears join the tour, the park wardens are always in contact with each other by walkie talkie, and while one warden leads the group, others stand guard along the perimeter of the fort walls. The groups are herded together for safety, and the wardens are very insistent on this safety measure. On my tour a family group refused to try and keep up with the rest of us and the warden continually stopped us to wait. Finally, in complete exasperation, he made them go back to the boat and wait for us there.
