Located in the northwest corner of the park, just below the travertine terraces of the hot springs that gave the property its name, Mammoth Hot Springs Hotel has recently broken ground on the second phase of a two-part renovation that is updating the historic 1936 structure’s 97 guest rooms. The 118 basic-but-comfortable cabins are still available in the meantime. While some have en-suite bathrooms (a few enjoy an enclosed six-person hot tub), others require sharing lavatory and shower facilities. All guests have access to the hotel’s restaurant and grill—a good spot for sipping a huckleberry margarita at the end of the day—but most can be found observing the elk and bison that roam free on the grounds from their cabins’ small front porch. If you need a break from wildlife viewings, self-guided tours of old Fort Yellowstone, built for the Army cavalrymen who once protected the land and which today houses the park’s headquarters, are available.
