Absolutely fantastic trip and I will be doing it again for sure. I cannot how believe how knowledgeable my guide was and how he was able to always pick the perfect place to be. As we approached old faithful, he points and says let’s stand here. You will not be able to see the vent where the crowd is. He was right! Every one else got a face full of cold steam and I got the best pictures of the eruption. This is THE trip to go on. Do not hesitate to book these guys. They KNOW Yellowstone.
