There's a guy who keeps huskies chained up on some land outside of town that does not technically belong to him. It is well known around town that he baits the bears with the dogs' food and then charges tourists to see them up close and even interacting with the dogs (you may have seen cutesy photos of polar bears and huskies playing together on the internet or elsewhere - these are likely from there). Locals refuse to pay because they know that he doesn't own the land, so he can't legally charge people to go there, but tourists often don't know this (or care?).
We were planning to partake in a dog-sledding trip until we were told that you pay $90 for about a 15 minute ride followed by a cup of hot chocolate with the owners. Of course, if you are really dying to try this mode of transportation, then maybe it's worth it for you, but just a heads up!
Also, despite its tundra location, Churchill often does not have snow yet during polar bear season, so either wait till you get there to book or be prepared to go on a sled with wheels!
Unique Suggestions: Support local tour operators. There's a guy, Gerald something, who runs dog-sledding tours and lives in Churchill. There should be posters around advertising his tours.
If the Polar Bears become tourists and venture into the town, then they end up "trapped" in the Polar Bear prison and later moved on up (by helicopter) and out (of town).
Unique Suggestions: We were taken to see the prison during a trip around towm.
Fun Alternatives: visiting the "trap" is fun for us but the bears should give it a miss!
