Here's my recommendation for the best Yellowstone 3-Day Itinerary to maximize your time!
Roosevelt Arch, Boiling River/Gardiner River, Mammoth Hot Springs, Golden Gate Canyon Drive, Roaring Mountain, The Hoodoos, Sheepeater Cliff, and Lamar Valley.
Hayden Valley, Yellowstone Lake, Dragon’s Mouth Springs & Mud Volcano, Grand Canyon of the Yellowstone, and Dunraven Pass
Norris Geyser Basin, Artist Paintpot, Fountain Paint Pots, Midway Geyser Basin, Old Faithful Geyser Area, and West Thumb Geyser Basin.
Canyon Lodge & Cabins, Canyon Campground, Yellowstone Gateway Inn, Old Faithful Inn
Yellowstone is enormous and you'll want to minimize your drive time. Choosing centrally located lodging or moving to different sections of the park can save you HOURS of time in the car!
