3 days (approx. 72 hours)
Suitable for travelers with basic fitness; involves short walks and standing; not strenuous but requires mobility for boardwalks and overlooks.
A compact, three-day push from Salt Lake City that stitches the alpine drama of Grand Teton to Yellowstone’s geothermal spectacle. Expect early starts, wildlife-rich valleys, and the parkland highlights—Grand Prismatic, Old Faithful, Artist Point—delivered with practical logistics and expert timing.
At 7:00 a.m. the bus pulls away from Salt Lake City under a pale, high desert sun and the first hint of the Tetons appears on the horizon like a jagged page ripped from a geology textbook. Over three days the route tightens into an immersion: alpine serrations of Grand Teton give way to the steaming, color-streaked basins of Yellowstone, and each stop flips between hard rock and boiling water as if the earth itself is showing you its private rooms.

Most major viewpoints and geyser areas are busiest in late morning; early departures increase wildlife sightings and quieter photo opportunities.
Daytime in the parks can be warm while mornings and higher elevations stay cool—pack lightweight insulating layers and a wind shell.
Thermal areas are fragile and dangerous—boardwalks protect you and the features; do not step off them for photos or shortcuts.
Hydration is essential at altitude and binoculars turn roadside stops into close-up wildlife encounters without approaching animals.
Yellowstone became the world’s first national park in 1872 after surveys by 19th-century expeditions; nearby Jackson Hole’s name derives from early French trappers who called the range 'les tétons'.
Both parks enforce strict wildlife viewing distances and require visitors to stay on boardwalks in thermal areas; packing out trash and respecting closures helps protect fragile ecosystems.
Support and traction for uneven boardwalks, wet ramps near waterfalls, and short hiking loops.
Temperatures vary from valley heat to cold mountain mornings; layers let you adapt quickly.
Keep hydrated at altitude; refill where available and filter if needed during remote stops.
