2452North saidI would highly recommend that ferry trip. you are going up the straights thru some beautiful country and I'm sure you would enjoy it. The highway from Rupert to PG is called the Yellowhead, #16 and is two lane paved in good shape...lots of small towns to travel through, mountains etc....watch for wildlife on the road.
If you take 5 south to Kamloops then you can hook up with the Coquihalla to Vancouver which is twinned divided highway. You mite wanna check with BC tourism online for more info, but If you like the outdoor beauty, then you are choosing a very beautiful and diversified trip.
best of luck
Thanks, man! It's all coming together nicely, even w/ no cabin on the ferry from PH to Rupert! Poring over tourist guides, maps, googling like crazy, and lovin' every minute of it! I'm going to overnite near Tweedsmuir and Francois Lake, swing SE from PG to Jasper and Banff, and then down to Kelowna before I head back to SEA and PDX. Those 19 hours of daylight are going to be the best! Another nice surprise: Canadian lodgings are very inexpensive! I am definitely psyched!
