The beauty of sleeping at Mallard Lake was that an 11 mile loop would allow me to explore Biscuit Basin, Midway Geyser Basin, and Upper Geyser Basin at my leisure before returning to the lake for night two. Instead of worrying about parking spots and traffic, I could focus on hiding from thunderstorms and getting back to the tent in time to make ramen before dark.
But seriously folks, this three-mile-long section of the park boasts so many geological peculiarities that the best way to appreciate it is on foot. Having somewhere nearby to sleep was just icing on the geothermal cake.
