This afternoon, you're headed due south for an up-close-and-personal view of Yellowstone Lake. The largest high-elevation lake in North America and nearly 400-feet deep in places, it's too cold for swimming but is wonderful to explore by kayak or canoe. Because of the lake's many hidden underwater geysers, submerged fumaroles and other geothermal features, we recommend a guided tour with one of the many outfitters in the area. After your paddle, enjoy a rewarding dinner in the charming Lake Yellowstone Hotel Dining Room before bidding farewell to the park — until next time.
