Trip Planning · From Seattle
Everything Pacific Northwest visitors need to plan the perfect Yellowstone & Grand Teton trip — the 2-day I-90 drive, direct flights, and the basecamp that puts both parks in reach.
For most Seattle visitors, flying wins on time and often on cost. The drive is beautiful but consumes 4 days round-trip.
Best if you have 10+ days and want a Pacific Northwest road trip. Bring all your gear, stop in Missoula or Coeur d'Alene, and enjoy I-90 scenery through the Bitterroots.
Best for trips of 7 days or less. Alaska and Delta run direct SEA → BZN seasonally. Pick up an SUV at the airport and save 4 full days vs driving.
Direct from SEA on Alaska and Delta (seasonal). Best balance of price, options, and drive time. Drive south on US-191 through Big Sky.
Closest airport to our cabin but requires a connection from SEA (usually SLC or DEN). Good pick if BZN fares spike.
Most scenic arrival. Direct from SEA on Alaska seasonally. Premium pricing — pick this if Grand Teton is your priority.
Cheapest fares from SEA and biggest selection (Delta hub). Worth it only if savings exceed $200/ticket.
The classic route: I-90 East across Washington, Idaho, and Montana → US-287 South at Three Forks → US-20 East into Idaho. About 830 miles total to Island Park.
I-90 East across Snoqualmie Pass and the Columbia Plateau, through Spokane and Coeur d'Alene. Missoula has great breweries and an easy walkable downtown for an evening.
Continue I-90 East to Three Forks, then US-287 South past Henrys Lake and into Island Park. Bonus: drive past the West Yellowstone entrance turn-off.
Most Seattle visitors burn time and money jumping between hotels in Bozeman, West Yellowstone, and Jackson. Island Park solves that — one cabin, both parks, no daily packing.
West Entrance is a quick US-20 drive — be at Old Faithful by 8 AM.
Day trip to Jackson, Snake River, and Mormon Row — back for the hot tub by dinner.
Cabin pricing is a fraction of Jackson Hole hotels — and you sleep in actual lodgepole forest.
