The national parks in Wyoming are headlined by Yellowstone and Grand Teton, two neighboring giants that together form one of the greatest road trips in the United States. Wyoming's high plains, geyser basins, and jagged peaks pack an astonishing amount of scenery into a single state, and the two parks sit just a short drive apart. This guide explains what each park offers, how to connect them, when to go, and where to stay so you can plan with confidence.
How many national parks does Wyoming have?
Wyoming contains two national parks: Yellowstone National Park, the world's first national park, and Grand Teton National Park just to the south. The state also holds Devils Tower National Monument and the John D. Rockefeller Jr. Memorial Parkway that links the two parks. Together they anchor a region loaded with national forests and wildlife refuges. For the complete regional overview, see our guide to national parks in Wyoming.
What makes Yellowstone special?
Yellowstone is famous for its geothermal wonders, including Old Faithful, the rainbow-colored Grand Prismatic Spring, and the Grand Canyon of the Yellowstone with its thundering waterfalls. It is also one of the best wildlife-watching destinations in the country, with bison, elk, wolves, and grizzly bears roaming the Lamar and Hayden valleys. Most of the park lies in Wyoming, though its edges spill into Montana and Idaho. Our Yellowstone National Park guide covers loops, geyser basins, and lodging.
Why visit Grand Teton?
Grand Teton National Park delivers some of the most dramatic mountain scenery in North America, with the Teton Range rising abruptly above the Snake River and a string of glacial lakes. It is smaller and more compact than Yellowstone, making it easy to combine hiking, paddling, and wildlife viewing in a single day. The town of Jackson sits just south of the park with restaurants and lodging. See our Grand Teton National Park guide for the best viewpoints and trails.
Can you visit both parks in one trip?
Yes, and most travelers do. The two parks are connected by the scenic Rockefeller Parkway, so you can drive from the Tetons to Yellowstone's south entrance in under an hour. A common plan is to spend two or three days in each park, basing in Jackson for the Tetons and near Old Faithful or the park's north for Yellowstone. Reserve lodging far in advance, as rooms inside both parks sell out months ahead.
When is the best time to visit Wyoming's parks?
Summer, from June through early September, offers the fullest access, with all roads and facilities open, though it is also the busiest season. Late spring and early fall bring fewer crowds, active wildlife, and beautiful light, but some services close and mountain weather can turn quickly. Winter transforms both parks into a snowy wonderland accessed by snowcoach or skis. Always check current-year road openings, reservation rules, and fees before you travel.
What wildlife can you see in Wyoming's parks?
Wyoming's parks are among the most wildlife-rich in the country. In Yellowstone, the Lamar Valley is often called America's Serengeti for its herds of bison and its resident wolf packs, while Hayden Valley is prime grizzly and elk habitat. Grand Teton adds moose along the Snake River, pronghorn on the sagebrush flats, and bald eagles overhead. Always keep a safe distance, carry bear spray on trails, and never feed or approach animals.
Where should you stay near Wyoming's parks?
Inside the parks, historic lodges such as the Old Faithful Inn and Jackson Lake Lodge book up nearly a year ahead. Gateway towns give you more flexibility: Jackson and Teton Village serve Grand Teton, while West Yellowstone, Gardiner, and Cody are convenient bases for different Yellowstone entrances. Campers can choose from numerous reservation and first-come sites, but demand is high in July and August.
FAQ
Is Yellowstone entirely in Wyoming?
About 96 percent of Yellowstone lies in Wyoming, with small portions extending into Montana and Idaho. All five park entrances are reachable by car in summer.
How far apart are Yellowstone and Grand Teton?
The parks share a boundary connected by the Rockefeller Parkway. It is roughly a one-hour drive between Grand Teton's northern end and Yellowstone's Old Faithful area, depending on traffic and wildlife jams.
Do you need reservations for Wyoming's national parks?
Neither park currently requires a timed-entry reservation to drive in, but lodging and camping fill up quickly. Confirm the current-year rules and book accommodations early.
Is Wyoming good for a first national park trip?
It is one of the best introductions to the national parks, combining geysers, mountains, and abundant wildlife within a compact area. First-timers should allow at least five days to see both parks without rushing.
