The world's most famous geyser, erupting every 60-110 minutes to heights of 130-180 feet. Free with park entry ($35/vehicle, valid 7 days). Predicted eruption times posted at the visitor center. Arrive 30 minutes early for front-row bench seating. The adjacent Old Faithful Inn (1904) is the largest log structure in the world.

Grand Prismatic Spring

Grand Prismatic Spring

The largest hot spring in the US (370 feet across) with stunning rainbow-colored rings of thermophilic bacteria. Free with park entry. The Grand Prismatic Spring Overlook trail (0.8 miles, easy) provides the best aerial view — essential for photos. The boardwalk at basin level lets you feel the heat. Allow 1.5 hours.

Lamar Valley — American Serengeti

Lamar Valley — American Serengeti

The best wildlife viewing in North America. Dawn and dusk bring bison herds, wolves, grizzly bears, elk, and pronghorn to this broad valley in the northeast. Free with park entry. Bring binoculars and a spotting scope. The wolf packs are most active October-April. Allow half a day.

Mammoth Hot Springs

Mammoth Hot Springs

Terraced limestone formations created by hot water depositing travertine over thousands of years. Free with park entry. The formations change constantly — what was white last year may be dry and brown now. Upper and Lower Terraces are connected by boardwalks. Allow 2 hours. The elk herd often grazes on the lawns.

Grand Canyon of the Yellowstone

Grand Canyon of the Yellowstone

A dramatic 20-mile canyon up to 1,200 feet deep with two major waterfalls. Artist Point viewpoint (Upper Falls: 109 ft, Lower Falls: 308 ft) is the park's most photographed spot. Free with park entry. Uncle Tom's Trail (328 steep steps) gets you close to the Lower Falls spray. Allow 2-3 hours.

Wolf Watching in Lamar Valley

Wolf Watching in Lamar Valley

Hidden gem: Yellowstone's wolf reintroduction in 1995 is one of ecology's greatest success stories. Several packs roam the Lamar and Hayden Valleys. Join the dedicated wolf watchers who set up scopes at dawn at pullouts near Slough Creek. Peak season is winter when elk are in the valleys. Free with park entry.

Planned Itinerary

7-Day Yellowstone Itinerary

1

Arrival & West Yellowstone Gateway

Fly into Bozeman (BZN) or Jackson Hole (JAC) and drive to West Yellowstone, the most popular park gateway town.

Arrive at Bozeman Yellowstone International (BZN)(1 hour)

Rent a car (essential). Drive 90 miles south to West Yellowstone (1.5 hours via US-191). Alternatively, fly into Jackson Hole (JAC), 60 miles south of the park

Check into West Yellowstone lodging(1 hour)

Budget: Explorer Cabins (from $130/night); mid-range: Kelly Inn ($180-250); or try in-park: Old Faithful Inn ($250-400, book 6-12 months ahead). Gas up and buy groceries at the Albertsons — in-park options are limited and expensive

Grizzly & Wolf Discovery Center(1.5 hours)

A wildlife sanctuary in West Yellowstone with grizzly bears and wolf packs in naturalistic habitats. $15 adults. Open 8:30AM-8PM in summer. A great primer before seeing them wild in the park

Pick up bear spray(30 minutes)

Rent bear spray at any visitor center ($10/canister rental) or buy at outdoor shops in town ($45-55). Mandatory for all hikes. Holster it on your hip, not in your backpack

2

Old Faithful & Upper Geyser Basin

Enter the park from the West Entrance and head straight for the world's most famous geyser and the surrounding thermal wonderland.

Drive to Old Faithful(45 minutes)

Enter via West Entrance ($35/vehicle for 7-day pass). Start early (by 7AM) to beat traffic. The 30-mile drive through the Madison River valley may have bison on the road

Old Faithful Geyser eruption(1.5 hours)

Erupts every 60-110 minutes to 130-180 feet. Predicted times posted at the visitor center. Arrive 30 minutes early for front-row bench seating. The adjacent Old Faithful Inn (1904) is the world's largest log structure — walk through the lobby even if not staying

Upper Geyser Basin boardwalk(3 hours)

5-mile loop past 150+ thermal features. Highlights: Morning Glory Pool (brilliant blue), Grand Geyser (tallest predictable, erupts every 6-7 hours), Castle Geyser, and Chromatic Pool. Stay on boardwalks — ground can be thin crust over boiling water

Lunch at Old Faithful Lodge cafeteria(45 minutes)

Basic but functional. Burgers $12-15, soup and salad $8-10. The patio has geyser views. Alternatively, pack lunch from West Yellowstone

Biscuit Basin(1 hour)

Short detour 3 miles from Old Faithful. Sapphire Pool is one of the park's most stunning — a deep, perfect blue. Easy 0.6-mile boardwalk loop. Less crowded than Upper Geyser Basin

3

Grand Prismatic Spring & Midway Basin

Visit the park's most colorful thermal feature — the rainbow-ringed Grand Prismatic Spring — and explore the firehole river area.

Grand Prismatic Spring Overlook trail(1.5 hours)

The 0.8-mile Fairy Falls trailhead parking lot is the starting point. The overlook provides the aerial view essential for photos — the basin-level boardwalk only shows steam. Arrive before 10AM for fewer crowds. The rainbow colors are thermophilic bacteria at different temperatures

Midway Geyser Basin boardwalk(1 hour)

Walk over the 370-foot-wide Grand Prismatic from the boardwalk level. Feel the heat. Excelsior Geyser crater dumps 4,000 gallons/minute of boiling water into the Firehole River. Free with park entry

Firehole Canyon Drive(30 minutes)

One-way scenic road with the Firehole Falls and a swimming area — one of the only places in Yellowstone where you can legally swim in thermally heated river water. Free

Hayden Valley wildlife drive(2.5 hours)

Drive slowly through this broad valley in the park's center. Bison herds, elk, coyotes, and occasionally grizzly bears and wolves. Use pullouts — never stop in the road. Binoculars essential. Best in late afternoon

4

Grand Canyon of the Yellowstone

The park's dramatic 20-mile canyon with two major waterfalls and colors that rival any slot canyon in the Southwest.

Artist Point(1 hour)

The park's most photographed viewpoint — Lower Falls (308 feet) framed by the yellow canyon walls. Short paved walk from parking. Arrive before 9AM for the best light and fewer people

Uncle Tom's Trail(1.5 hours)

328 steep metal steps descending to a platform with a thundering close-up view of the Lower Falls spray. Strenuous but exhilarating. The steps can be slippery — hold the railings. Not for those afraid of heights

Brink of the Upper Falls trail(45 minutes)

Walk to the very edge where the Yellowstone River tips over the 109-foot Upper Falls. The power is visceral. Short 0.5-mile trail, moderately steep

Lunch at Canyon Lodge dining room(1 hour)

The park's largest dining facility. Bison burgers $18, trout $22, salads $12. Reservations recommended for dinner but walk-ins usually fine for lunch

South Rim and Inspiration Point(1.5 hours)

Walk the South Rim trail for different canyon perspectives. Inspiration Point at the end offers a wider panorama than Artist Point. The canyon walls glow orange in afternoon light

5

Lamar Valley Wildlife Safari

Dawn wildlife expedition to the American Serengeti — North America's best place to see bison, wolves, bears, and elk in the wild.

Pre-dawn drive to Lamar Valley(1.5 hours)

Leave lodging by 5AM. The 50-mile drive from Canyon Village takes about 1.5 hours. Dawn and dusk are the only times for wolves and bears. Bring coffee, binoculars, and a spotting scope if you have one

Lamar Valley wildlife watching(4 hours)

Park at pullouts near Slough Creek and along the Lamar River. The dedicated wolf-watchers who set up scopes daily are friendly and will share sightings. Bison herds of hundreds, pronghorn, coyotes, and with luck, wolves and grizzlies. Stay 100 yards from bears/wolves, 25 yards from bison

Tower Fall(45 minutes)

A 132-foot waterfall near Tower Junction. Short walk to viewpoint. The volcanic columns above the falls are impressive. Free with park entry

Lunch at Roosevelt Lodge(1 hour)

The most rustic lodge in the park. The Roosevelt Cookout experience (horseback or wagon ride to an outdoor BBQ, $60-80) is a classic Yellowstone tradition. Book at yellowstonenationalparklodges.com

Mammoth Hot Springs(2 hours)

Drive north to terraced limestone formations. Upper and Lower Terraces connected by boardwalks. The formations change constantly. Elk often graze on the lawns. The historic Mammoth Hotel and Albright Visitor Center are worth exploring

6

Rest Day — Yellowstone Lake & Hot Springs

A slower day around the park's largest lake and the bubbling mud pots of Yellowstone's thermal areas.

Yellowstone Lake morning(2 hours)

The largest high-elevation lake in North America (7,733 feet, 136 sq miles). Drive the shoreline from Bridge Bay to Lake Village. The Lake Hotel (1891) is the park's most elegant — have coffee in the sunroom even if not staying. The lake freezes half the year and can have whitecap waves

West Thumb Geyser Basin(1 hour)

Thermal features right on the lakeshore — geysers emptying directly into Yellowstone Lake. Easy boardwalk loop. Fishing Cone geyser was historically used to cook caught fish (now illegal). Smaller crowds than Old Faithful area

Mud Volcano area(1 hour)

A 0.7-mile boardwalk loop past churning mud pots, fumaroles, and Dragon's Mouth Spring (a cave belching steam and water with a roar). The sulfur smell is intense but the features are unlike anything at the geyser basins

Lunch at Lake Hotel dining room(1.5 hours)

The most refined dining in the park. Lake trout, bison meatloaf, huckleberry desserts. Entrees $18-35. The lakeside setting is serene. Reservations recommended

Afternoon walk along Storm Point Trail(1.5 hours)

Easy 2.3-mile loop from Indian Pond to a rocky point on Yellowstone Lake. Bison and yellow-bellied marmots common. Check for trail closures due to bear activity

7

Departure Day

Final morning in Yellowstone before driving to Bozeman or Jackson Hole for your flight out.

Sunrise at your closest viewpoint(1 hour)

Whether it is Hayden Valley, Lamar Valley, or Yellowstone Lake — one last dawn in the park is worth the early alarm. The steam from thermal features in cold morning air is ethereal

Last stop at Old Faithful(1 hour)

One more eruption if your route passes through. The gift shop has quality souvenirs — maps, books, and Yellowstone-branded gear

Drive to Bozeman (BZN) or Jackson Hole (JAC)(2 hours)

Allow extra time for wildlife jams and construction. BZN is 90 miles north (1.5-2 hours from Mammoth). JAC is 60 miles south (1-1.5 hours from West Thumb). Fill gas inside the park — outside is cheaper but further

Travel Tips

Visa & Entry

US Entry Requirements

US citizens need no visa. Citizens of Visa Waiver Program countries (UK, Australia, Japan, most EU) need an approved ESTA ($21) before arrival. Indian citizens need a B1/B2 visa. The park is in Wyoming with entrances also in Montana and Idaho.

Safety

Wildlife Distance Rules Are Law

Stay at least 100 yards (91m) from bears and wolves, 25 yards (23m) from bison, elk, and other animals. Bison injure more visitors than any other animal — they can sprint at 35 mph. Never approach, feed, or take selfies with wildlife. Carry bear spray ($10 rental at visitor centers) on all hikes.

transport

Book Lodging 6-12 Months Ahead

In-park lodges (Old Faithful Inn, Lake Hotel, Canyon Lodge) sell out 6-12 months in advance for summer. If sold out, try West Yellowstone, Gardiner, or Cooke City gateway towns. The park is 60 miles across — location matters for your itinerary. Camping reservations open in batches starting in fall.

Beat the Traffic Jams

July-August traffic is intense — bison on the road (jams), construction, and 4 million annual visitors. Start driving by 7AM to beat crowds at major sites. The loop road between Old Faithful and Canyon is the busiest stretch. Consider visiting in September when crowds drop 40% but weather is still good.

Budget

The $35 Vehicle Pass Is a Bargain

The 7-day vehicle pass costs $35. The America the Beautiful Annual Pass ($80) covers all 400+ national parks and federal recreation areas for a year — worth it if visiting 3+ parks. Gas is available at a few stations inside the park but prices are 20-30% higher than outside.

Local Customs

Thermal Features Will Kill You

Yellowstone's geothermal pools are acidic and boiling (200°F+). Stay on boardwalks at all times. People have died falling into hot springs — the ground can be thin crust over scalding water. Never throw objects into thermal features. Pets are not allowed on boardwalks or trails.
