Location: Yellowstone National Park, Wyoming

Ideal audio accompaniment: “Afternoon Delight” by Starland Vocal Band

 

Although a cone geyser that dramatically ejects thousands of gallons of boiling water every 91 minutes may be a touch suggestive for newly acquainted lovebirds, there’s no denying the majesty — and the amorous appeal — of Yellowstone’s most famed geothermal feature. Keep in mind that the jam-packed viewing benches surrounding Old Faithful don’t lend themselves to any sort of serious canoodling, so visitors who are left feeling a bit frisky by the performance can always decamp to a private room at the nearby historic Old Faithful Inn.
