The
Sea-to-Sky Corridor, often referred to as
the Corridor, or the
Sea to Sky Country, is a
region in
British Columbia spreading from
Horseshoe Bay through
Whistler to the
Pemberton Valley and sometimes beyond to include
Birken and
D'Arcy. From Whistler on up, the region overlaps with the older and more historic
Lillooet Country, of which
Squamish, at the region's centre, was once the southward extension in the days when it was the rail-port terminus from the Interior, via Lillooet, and accessible from the Lower Mainland only by sea. Most of the region is in the
Squamish-Lillooet Regional District, although south of
Brittania Beach a small part of the region is in the
Greater Vancouver Regional District.
