While Theodore Roosevelt spent two days exploring the backcountry of Yosemite with John Muir, he spent 16 days in Yellowstone. Even that wouldn’t be enough of this amazing place. If I only had a day I’d visit the Upper Geyser Basin with the infamous Old Faithful, and the Norris Geyser Basin, which I continue to find one of the parks jewels. But then again, how to not include the Lamar and Hayden Valleys? And what about the Lake region? What a beautiful quandary to find oneself in. When you’re planning your trip to Yellowstone, do yourself a favor and give it more time. You and the park both deserve it.
