Seattle, Washington

Located between Puget Sound and Lake Washington in the Pacific Northwest, Seattle is known as the Emerald City. Seattle was originally a fishing, logging, and coal-mining town but has transformed into a cultural haven over the years. Boeing and Microsoft have both played large roles in the city's development to a less rough-around-the-edges metropolis. In recent years, coffee and music have kept Seattle at the forefront of the cultural discussion.

Visiting Seattle

Flights into Seattle land at the Seattle-Tacoma International Airport, located south of the city center. From the airport, you can use the Central Link light-rail service, buses, shuttles, and taxis to travel into the city. If you prefer to rent a car during your trip to Seattle, an impressive 23-acre rental car facility is also located at the airport.

Seattle is known for its rainy, overcast climate, but the city does experience many sunny days between June and September, with most of the rain and precipitation falling between November and January. Summers are quite pleasant, with temperatures reaching into the low 70s Fahrenheit. In the winter, temperatures on average only drop down to the mid-40s Fahrenheit.

Regardless of when you visit, Seattle always has something to offer. The famous Space Needle, built for the 1962 World's Fair, offers breathtaking views of the city and the surrounding mountains from over 500 feet in the air. This iconic landmark is a must-see for any visitor to the Emerald City. Equally iconic is the Pike Place Market, which offers fresh seafood and produce year-round. This public farmers' market is one of the oldest in the US and is home to antiques dealers, collectible shops, produce stands, craft stalls, and the famous Pike Place Market itself, where salmon throwing has made its fishmongers the stuff of legends.
