As BeBop mentioned,there is almost a full closure on all off road travel to most of southern BC(from about 100 mile house south).The only exceptions right now are a few Industrial access areas and some provincial park campsites(but all trails and travel in the areas are closed) and private property/lodges.
Almost everywhere is either off limits or severely restricted,even places like the Squamish and Upper Vedder.It's that bad.
The Fraser/Harrison areas are about the only real option right now until we get some serious rain.
For some updated info on road closures see http://www.for.gov.bc.ca/DSQ/Enginee...nformation.htm
Sorry to be the bearer of bad news,but our province is having one of the worst years in history right now and EVERYONE MUST follow these rules.
