| Breakfast: ||Breakfast at nearby restaurant.|
| Morning: ||A day to experience the Great Caldera’s underground plumbing system begins with a journey via Gibbon River, its graceful falls cascading over the caldera rim then crystal clear Firehole River which drains geyser basin country. Find out about cataclysmic volcanic eruptions that laid the foundation for the world’s most diverse and intact collection of geysers, hot springs, mud pots and fumaroles. Yellowstone National Park’s 10,000 thermal features – hot springs, mudpots and fumaroles - and over 300 geysers are a reminder of the area’s recent volcanic past. First stop is the Fountain Paint Pot area in Lower Geyser Basin, which, at about 18 square miles, is the largest geyser basin in Yellowstone. Enjoy the sounds,smell and sight of Fountain Paint Pot, named for the yellows, browns and reds of the “pots.” Your boardwalk discovery here offers beauty, grand vistas and geysers including Clepsedra and Fountain, hot springs like Silex Spring and Celestine Pool and fumaroles or steam vents such as Sizzler.
| Lunch: ||Sack lunches in the Park.|
| Afternoon: ||The destination this afternoon is Old Faithful. If time allows, an eye popping investigation will continue at Midway Geyser Basin, named Hells Half Acre by Rudyard Kipling who visited Yellowstone in 1889. Discover two of the largest hot springs in the world. At 111 feet deep, Grand Prismatic Spring is Yellowstone's deepest hot spring and, at 200 feet wide, the largest in North America. Located nearby on this fabulous boardwalk venture is a dormant geyser, Excelsior Geyser, now considered a productive hot spring, discharging 4050 gallons of boiling water per minute into the Firehole River.
On to Old Faithful and the Upper Geyser Basin. The hot water beneath the surface here is over 400 degrees F; it cools to around 200 degrees F as it surges from the geysers. Old Faithful's eruption discharges about 8,500 gallons of hot water as it erupts to heights between 100 and 180 feet every 80 minutes or so. Enjoy Old Faithful then walk a portion of Geyser Hill's meandering boardwalk to view geysers and hot springs including Giantess, Lioness and Grotto. Enjoy the history and parkitecture of the legendary Old Faithful Inn, designed by Robert Reamer and built of local stone and logs during the winter of 1903-04. This treasure is now a National Historic Landmark and one of the few remaining log hotels in the country.
Moderate walking, up to two miles per day on asphalt paths, stairs and boardwalks; some hilly areas. Those choosing not to walk may wait on the bus or at the trailheads.
| Dinner: ||Dinner at nearby restaurant.|
| Evening: ||Free evening to enjoy the grassy, back patio perched high above the mighty Yellowstone River that intersects the town. Often times, a patient search with binoculars reveals elk, deer, geese, sometimes rabbit across the river, sometimes beaver in the river. Take time to stroll downtown and enjoy the flavor of a small, western Montana gateway community.|
