This subregion consists of Whatcom County and Skagit County
Bellingham International Airport (BLI) is the primary airport serving the region. Seattle-Tacoma International Airport (SEA), while located a way to the south of Seattle, is the closest national-grade airport in the USA. Vancouver International Airport (YVR), while across the border in the Lower Mainland of British Columbia, Canada, is sometimes convenient.
From British Columbia
There are five land border crossing points, between the Lower Mainland region of British Columbia, Canada and the Northwest Cascades region of Washington state, USA. They are referred to by different terms in Canada and the US.
Visitors travelling to Vancouver by car across the U.S. border should be aware that there are often lengthy lineups at the border, in either direction. During summer, waits at the border can exceed three hours during peak times.
Inform yourself about the waits, and you can either delay your crossing until the lines subside, or choose the quickest crossing, or at least set your expectations. You can see current wait time forecasts for both directions on the Canada Border Services Agency website , and for US-bound traffic on the US Customs and Border Protection website . Washington State also maintains graphs of estimated times in both directions . It can be helpful to view webcams of the border lineups; Canada-bound on I-5  and US-bound at most crossings . Two AM stations give regular updates on border lineups in both directions: News 1130 (1130 on the AM dial) every 10 minutes beginning at one minute past the hour, and AM 730 every 10-15 minutes. Electronic signs near the border on I-5, BC 99, and BC 15 give the current wait times at both the Peace Arch and Pacific Highway crossings, allowing you to choose the shorter option.
The Nexus Land program lets travellers who fill out an application and pass a security check use express lanes through US-Canada land borders by presenting a Nexus card. However, you may only use the express lanes if everyone in your car has a Nexus card. There are also Nexus programs for air and marine travel.
From other places in Washington
From Seattle and Puget Sound
Head north on I-5 from Seattle. Mount Vernon, Burlington, Bellingham, Blaine and Ferndale are directly on the highway. Other towns are usually a short drive away on local highways: see the individual Get in sections of the towns.
From Eastern Washington
The North Cascades Highway (SR-20) runs from the Okanogan valley area across the Cascades to Burlington and Sedro-Woolley; it is always closed in winter. Two passes across the Cascades further south are usually open all year (except in storms): US-2 over Stevens Pass from Wenatchee and I-90 over Snoqualmie Pass from Ellensburg: when you reach I-5 you will have to turn north to reach this region.
