In 2007, we drove north on the Cassiar and returned on the Alaska Highway. While boondocked in a rest area south of Fort Nelson because we were unable to get a campsite, we decided the Cassiar Highway would be our preferred route on future trips.
In 2008 & 2009, we drove north on the Cassiar and returned home on the same route. The scenery is better southbound, even though it is all the same trees and mountains. All a matter of perspective, I think.
In 2010 we went north on the Alaska Highway and returned southward on the Cassiar.
The Cassiar route from Prince George to Whitehorse is about 210 km (130 miles) shorter than the Alaska Highway route from Prince George to Whitehorse.
See my page Highway 37A for pictures from Meziadin Junction to Stewart, Hyder, Fish Creek and Salmon Glacier. The Stewart-Cassiar Tourism Council's website has more info about businesses along the route, including commercial campgrounds. This brochure from the above noted website provides distances and lists available services: http://www.stewartcassiar.com/images/uploads/docs/sctcpamphlet-2010.pdf
The south end of the Cassiar Highway is a 2-lane paved road with paint lines and usually a bit of shoulder. It is very easy driving and good time can be made.

Meziadin Lake is near Meziadin Junction, where Hwy 37 and Hwy 37A meet. There are no facilities at Meziadin Junction. Fuel can be purchased in Stewart, or further north on the Cassiar at Bell II.
Highway 37A is a very scenic route that leads to
Stewart B.C. and Hyder, Alaska.
Salmon Glacier
is beyond Hyder and well-worth the drive to see it.
The campground at Meziadin Lake Provincial Park has many waterfront spots, as well as numerous sites with water views.

North of Meziadin Junction, the paved highway continues. The highway is good driving to Kinaskan Lake due to recent road upgrades.
