About 140 miles. If you take a Greyhound bus, it takes about 3 hours with a quick layover in Ellensburg, Washington. The cost is about $50.00 round trip. You can also take an airport shuttle from SEATAC airport to the Yakima airport. The light rail will get you to the airport. Alaska Airlines has flights between SEATAC and the Yakima airport.If you drive, you should find out what the pass conditions are since you will be driving through the Cascade mountain range. If the passes are closed, you can drive around, but that s a five hour trip. (It s very beautiful, however around the South end of the range.
