My sister and our 2 husbands recently took a 3 day tour to Yellowstone and Grand Teton. When we scheduled the tour months ago, we had many options to explore; many websites offered tours. I am so glad that we chose Teton Excursions. Our tour guide was Jason, who was knowledgeable, thoughtful and reliable. We departed from Jackson Hole, toured the Grand Tetons and Upper/ Lower Loops in Yellowstone, with overnight stops in West Yellowstone and Cody. We have had a Yellowstone trip on our bucket list for years, and are so glad that we did it with Teton Excursions. It was wonderful. They customized it to meet our needs and wants, and supplied great lunches and snacks along the way. The private van was spacious and comfortable, and it was convenient to have our luggage along with us, accessible along the way. Owners Aaron and Emily were available and responsive, even making suggestions for our plans outside of the tour. Tour guide Jason had good knowledge of the layout of the parks, the waterways, vegetation, and of the many animals we viewed along the way. It was a 5 star tour for me.
