Our mid-December one-day visit to northern yellowstone was incredible. We would highly recommend Andrea and would love to visit again in a different season just to see a different perspective. Andrea picked us up at our hotel in Bozeman at our agreed time of 6am. He has a new, well-equipped, upgraded and very comfortable black chevy suburban- the snow tires and heated back seats were a must for the snowy chilly day on which we visited. Andrea was very knowledgable about history and other details of the park and surrounding areas and inhabitants and gave us a great background en route to the park. We had such a great day, with elk and deer being our first sighting, followed by a pack of six wolves that we, along with some other locals who follow the wolves regularly, had the pleasure to watch using binoculars and high-res scopes provided by Andrea. He also shares the videos with you afterward so you have them to share with friends and family. The experience of chasing the wolves and watching Andrea and the other professionals communicate via their walkie talkies to help each other locate wildlife was so cool, and seeing the wolves alone would have been worth the trip. But we also saw many dozens of bison, including a nursing calf, which were just gorgeous. We then saw two golden eagles as well. Took an amazing hike through a very beautiful canyon, and the snow started coming down at that point, so it was a stunning winter wonderland hike we will never forget. We also saw many more elk, and then two coyotes that we stopped to view through the scopes for a while, followed by two more single coyotes. We also saw the mammoth hot springs, with a stop at the hotel, which had just opened that day. Very cool and a cute gift shop for souvenirs. Lastly we saw a large waterfall, which was only partially frozen and very beautiful, followed by a group of great horn sheep which were also very beautiful. The drive back was also stunning, as it was dark when we were initially driving to the park that morning. Seeing this area of yellowstone in the winter was very special! And Andrea was a fabulous host and guide and we learned so many interesting things. We absolutely loved the experience!
