Yellowstone
Wyoming, Montana & Idaho, USA

Getting there
America's first national park spreads across three states, though almost all of it sits in Wyoming. Most visitors fly into Bozeman, Montana (about 80 miles from the North Entrance at Gardiner) or Jackson Hole, Wyoming (about 60 miles from the South Entrance). Once inside, the Grand Loop Road links every headline sight, so a car is essential. Come with a full tank and a packed lunch; this is a very big park with long, slow, animal-stopping-the-traffic days.
Famous for
Yellowstone was the world's first national park, created in 1872, and it still feels like nowhere else on Earth. About half of all the geysers on the planet are here — Old Faithful erupting roughly every 90 minutes to around 100–180 feet is just the opening act. The park is also the only place in the US where bison have roamed continuously since prehistoric times, and the gray wolf's famous 1995 comeback began in the Lamar Valley.

Where to stay & eat
- Old Faithful Inn — the great log-and-stone landmark of the park, steps from the geyser's viewing boardwalks. Book many months ahead for summer.
- Mammoth Hot Springs Hotel — a good northern base near the Mammoth Hot Springs terraces and the park's main wildlife-watching valleys.
- Lake Yellowstone Hotel — the elegant yellow hotel by the lake shore; mornings on its porch are pure storybook.
- Campground cafés and general stores — most lodges have family-friendly dining rooms and quick cafés for packed-lunch supplies.
What to do

- Old Faithful & the Upper Geyser Basin — check the predicted eruption time at the visitor centre, then walk the boardwalks through the densest cluster of geysers on Earth.
- Grand Prismatic Spring — the boardwalk gives the ground view; the overlook trail at the Fairy Falls trailhead gives the postcard view from above.
- Lamar Valley wildlife watching — dawn is best. Scan the ridgelines with binoculars for gray wolves, grizzly bears, elk and pronghorn.
- Hayden Valley bison — huge herds graze here at sunrise and sunset; watch them from the road pullouts.
- Grand Canyon of the Yellowstone — Artist Point looks straight down the canyon to the 308-foot Lower Falls.
- Mammoth Hot Springs terraces — steaming terraces of mineral deposits, always changing colour and shape.

Jess's favourite
Dawn in Lamar Valley with binoculars
Nothing beats watching a whole meadow of bison wake up while you scan the treeline for a wolf. As a zookeeper, I've learned that patient watching beats chasing — the valley rewards the quiet ones. Bring coffee, bring layers, and let the animals come to you.
Good to know: Yellowstone is grizzly country — carry bear spray and know how to use it. Stay at least 100 yards from bears and wolves, 25 yards from everything else. Summer is busy; winter visits are magical — check nps.gov for seasonal road and lodge access. Photos: Wikimedia Commons (public domain / CC licensed).
Parks change: roads, reservations and opening dates in these guides were checked at the time of writing — always check nps.gov before you go.

Yellowstone: geysers, wolves, and Dad's stories
Summer, eight years ago
Dad used to tell me Yellowstone bedtime stories — about a geyser that kept perfect time, and valleys full of bison as far as you could see. I believed him the way kids believe everything, but I didn't know he was telling the truth until the steam of the Upper Geyser Basin hit me in the face that first morning. It smelled like a hot spring in a zoo, times a thousand, and I laughed out loud on the boardwalk like a little kid.
The geyser that kept its promise
The visitor centre had a little sign predicting Old Faithful's next eruption, and a whole crowd of us gathered on the benches like it was a concert. When it went — that first tall white column of steam and water climbing toward the sky — I thought about Dad's story: a geyser so faithful they named it that. Roughly every 90 minutes, day after day, for longer than anyone can remember. As a zookeeper, I'm used to animals keeping schedules — the big cats get restless at exactly 3pm — but a whole mountain keeping time? That's something else.
A rainbow you can smell
Grand Prismatic Spring doesn't look real. From the overlook, it's a perfect circle of deep blue, ringed with yellow and orange — and those colours are alive. The rangers explained that heat-loving microbes paint the rings, each species picking the temperature band it likes best. I work with microbes every day in the zoo's water systems, but seeing a whole rainbow made by bacteria, 370 feet across? I stood there with my mouth open like the tourists I was definitely not being.
Lamar Valley at dawn
We dragged ourselves up at 4:30am for the wolf watchers in Lamar Valley. Dad had told me the wolves were gone for most of a century — gone since the 1920s — and then, in 1995, fourteen of them came home in crates from Canada. Rangers now tell that story like a fairy tale, and it kind of is. We never saw a wolf, only far-off scopes and the excited whispers of people who had. But the valley was full anyway: a grizzly sow ambling with two cubs, a herd of elk, and bison — so many bison they crossed the road in a slow, shaggy river and we just sat and waited, engine off, grinning.
The bison roadblock
Here's what nobody tells you about bison: they are enormous, they know it, and they do not hurry. One massive bull planted himself in front of our car in Hayden Valley and stared at us with the patience of an animal that has never once lost an argument. The zookeeper in me was doing mental notes — horn spread, hump muscle, that wild eye — but mostly I was thinking: this is what the plains looked like before fences. From twenty-three animals in the early 1900s to thousands now. That's the comeback story I tell my keepers about.
Animals spotted
Wild sightings are never guaranteed — this was our honest tally over three days: bison (hundreds), elk (two herds), a grizzly sow with cubs (Lamar Valley), pronghorn (one lone buck), mule deer, and a chorus of coyotes at dusk. No wolves — the valley keeps that promise for another visit.
Story seed
Clarence finds a geyser in the Great Wood that erupts exactly on time, every day — and Pinafor, who is never on time for anything, decides to race it. What happens when the fastest squirrel meets the most punctual water?
Barnaby's note
"Jess, some promises are kept by mountains, and some comebacks take a whole century — the wolves waited for their valley, and the valley waited for them. You saw what patience looks like: a crowd of strangers sitting quietly at dawn, hoping together. Keep that patience close, my dear. The best things in your life are the ones worth waiting for."
