A perfect way to start our adventure in Yellowstone! Our guide Kate was knowledgeable and fun -- she adapted our trip to be the best for our family, sharing great background and history, and throwing in some adventure along the way for our teens. The number of sites you can see just within the valley is incredible, and beginning with a full day of valley exploration with a knowledgeable guide helped us plan the rest of our time in the park. Kate even texted a follow-up email with recommendations based on our time together. Amazing-- a must do!
