It was snowing heavy when we visited but in a way it made it nicer, Peter our driver picked us up at a nearby location and was very friendly. He brought us to the first camp and explained everything very clearly to us to where to go etc. You only get a 15min break before going to next camp, I'd suggest bringing snacks/water with you as the que gets long and you won't get time to rest/eat. It was emotional at times during the tour especially the gas chamber but its something everyone should do. "By standing on the fence you are siding with the oppressors"
