Yellowstone Entrances & Airports: Which One Fits Your Trip (2026)

Five year-round commercial airports serve Yellowstone: Bozeman and Billings in Montana, Jackson and Cody in Wyoming, and Idaho Falls in Idaho. A sixth, West Yellowstone's small seasonal airport, runs from early May to mid-October with service from Salt Lake City only. Which one you book decides which side of the park you'll realistically base on, so lock the flight and the lodging as one decision.

The pairings are straightforward. Bozeman is the most flexible pick — it feeds both the West Entrance and the North Entrance, which between them cover the geyser basins, Mammoth, and Lamar Valley. Jackson feeds the South Entrance and comes bundled with Grand Teton, making it the two-park airport. Cody feeds the East Entrance and the lake district. Billings and Idaho Falls are the value fallbacks: they often price better, at the cost of a longer approach drive to their nearest gates — Billings toward the North or Northeast side, Idaho Falls toward West Yellowstone.

One more airport truth: whichever you choose, plan on renting a car. Yellowstone has no park shuttle, distances on the 140-mile Grand Loop are real, and in 2026 you should pad drive times for construction delays of up to 30 minutes at points like the Gardner River High Bridge and the Canyon–West Thumb road. If your route lands you on the west side, West Yellowstone is the gateway town you'll be comparing against everything else.

If you're not sure which entrance to pick, pick this one. The West Entrance sits at the edge of the town of West Yellowstone, Montana — the gate is literally at the end of the main drag — and it's about 30 minutes from Madison Junction, the intersection that puts you on the road to Old Faithful and the geyser basins. No other entrance gets you to Yellowstone's headline thermal features faster, which is exactly what most first-timers came for.

The town itself is the biggest reason to base here. West Yellowstone has the deepest bench of gateway-town services of any entrance — lodging at every price point, restaurants, groceries, gear shops — so it works for families and anyone who wants a real town rather than a lodge hallway at 9pm. Fly into Bozeman for the standard approach, or use the seasonal West Yellowstone airport (early May–mid October, from Salt Lake City) if the schedule lines up.

The honest catch: popularity. This is the busiest arrival pattern in the park, and summer mornings bring gate lines — the fix is simply to be at the entrance early, before the mid-morning wave. The trade-off flips in winter, when the West Entrance becomes an asset of a different kind: it's a departure point for guided snowcoach and snowmobile trips into the interior, which run December 15, 2026 through March 15, 2027, when the roads beyond the gate are closed to regular cars.

The North Entrance at Gardiner, Montana is the only entrance with year-round road access into the park. The road from Gardiner through the park to Cooke City stays open to regular cars in every month, which makes this the one entrance where a January trip works without booking a snowcoach. If you're coming in winter, this isn't one option among five — it's the option.

Geography is the other argument. The North Entrance serves Mammoth Hot Springs, just up the hill from the gate, and puts you on the year-round road toward Lamar Valley — the park's premier wolf-watching ground. Base in Gardiner and you can be positioned for early-morning wildlife runs into Lamar without crossing half the park first. Fly into Bozeman for the shortest approach; Billings also works as the cheaper fallback on this side.

Who it's for: wildlife-first travelers, winter visitors, and anyone routing in from I-90 across Montana. The catch is the flip side of the West Entrance's strength — you're starting on the northern lobe of the figure eight, so Old Faithful and the geyser basins are your longest day trips, made longer in 2026 by construction delays of up to 30 minutes at the Gardner River High Bridge. One planning note for fall: Dunraven Pass, the high road on this side of the loop, closes October 12, 2026, ahead of the October 31 closure of most other park roads.

The Northeast Entrance at Cooke City, Montana opens directly into Lamar Valley — no transit drive, no junctions, just the gate and then the valley where the wolf watchers set up their scopes at dawn. For serious wildlife trips, no other entrance puts the main event this close to your morning coffee.

Getting there is the decision point, because there are two very different approaches. Year-round, you reach Cooke City from the inside — via the Gardiner–Cooke City road through the park, the same road that never closes to cars. Seasonally, you can arrive from the outside over the Beartooth Highway, which in 2026 opens May 22 and closes October 12. If the Beartooth is part of your plan, your trip has to fit inside that window, and an early-October booking is a gamble on the closure date.

The honest catch is services. This is the quietest entrance with the fewest amenities of the five — Cooke City is a small outpost, not a gateway town, and you won't find West Yellowstone's depth of lodging or dining. That's precisely the appeal for the right visitor: wildlife photographers, repeat Yellowstone travelers, and anyone who wants the park at its emptiest. Families who need options at dinner time should base at Gardiner instead and drive in.

The East Entrance is the Cody, Wyoming approach: over Sylvan Pass and down to Fishing Bridge and the Yellowstone Lake district. It opens May 1, 2026 — the earliest of the seasonal gates — and it's the natural route if you're flying into Cody's year-round airport or road-tripping across Wyoming.

The smartest way to use this entrance is usually as a door, not a base. Cody is a genuine destination town, but it sits far enough from the park's core that commuting in daily means long repeated drives over Sylvan Pass. The routing that works: spend a pre-park or post-park night in Cody, then enter once and sleep inside the park or continue your loop, rather than treating Cody as your nightly return point.

Who it's for: travelers building a one-way route — for example, in through the East and out through the North or West — and lake-first visitors who want to start at Fishing Bridge rather than the geyser side. The catch is position: you arrive on the eastern edge of the lower loop, so the geyser basins are a full cross-park drive, and in 2026 the Canyon–West Thumb construction (delays up to 30 minutes) sits on routes you'll likely use. In winter, the East joins West and South as a guided-oversnow entrance — snowcoach and snowmobile access only, December 15, 2026 to March 15, 2027.

The South Entrance exists for one itinerary above all: the two-park trip. It connects Yellowstone directly to Grand Teton National Park and the town of Jackson, Wyoming, so flying into Jackson lets you run both parks in a single line instead of backtracking. The road from the South Entrance to West Thumb opens May 8, 2026, which sets the earliest date this routing works.

Inside the gate, you arrive at the West Thumb and Grant Village corner of Yellowstone Lake — the southwest corner of the lower loop, positioned between the lake district to the east and the geyser basins to the northwest. That's a genuinely useful starting corner: from West Thumb you can turn toward Old Faithful or toward the lake on day one, whichever your itinerary leads with.

Who it's for: anyone doing Yellowstone and Grand Teton in one trip, which — if you're flying into Jackson — should be almost everyone. The catch is the calendar: this is a seasonal entrance, closed to cars until May 8, 2026 and part of the October 31 general road closure, with winter access limited to guided snowcoach and snowmobile travel from December 15, 2026 to March 15, 2027. If your dates fall outside the road season, the pairing itinerary doesn't work and you should re-plan around the North Entrance instead.

Here's the whole page as one decision. Geysers first, first visit, want a real town at the gate: West Entrance, fly Bozeman, base in West Yellowstone. Wildlife or a winter trip: North Entrance, fly Bozeman, base in Gardiner — it's the only gate open to cars year-round, with Lamar Valley up the road. Two parks in one trip: South Entrance, fly Jackson, run Grand Teton first. Already driving I-90 across Montana: drop south to the North or Northeast Entrance. Lake-first, or crossing Wyoming: East Entrance via Cody, best used as a pass-through night rather than a daily base.

Then check the calendar against your dates. Most park roads open in stages between April 17 and May 22, 2026, and close October 31 — with Dunraven Pass and the Beartooth Highway closing early on October 12. The East gate opens May 1, the South's road to West Thumb May 8. Outside December 15, 2026–March 15, 2027 winter operations (guided oversnow from West, South, and East; cars via the North only), a shoulder-season trip needs its entrance's opening date confirmed before you book anything nonrefundable.

The money and logistics are the easy part: $35 per vehicle covers seven days, no vehicle reservation is needed in 2026, and free entrance days include May 25, July 3–5, and November 11. Whichever gate you choose, add slack for construction — delays run up to 30 minutes at the Gardner River High Bridge and on the Canyon–West Thumb road — and remember the rule that outranks every airport fare: pick your lodging position on the loop first and let the entrance follow. If you can land a night at Old Faithful Inn , for instance, a West or South arrival suddenly beats anything cheaper on the far side of the figure eight.
