On Vancouver Island from Duncan to Tofino, about 5 hour drive and most of the highway are mountainous very much like Alberta Rockies, except you don't see snow, you see gorgeous crystal clear lake views, waterfalls, forests with deers and bears along the way (July/Aug).
Road pavement is excellent, but many unpredictable bends and elevation, I think government and construction workers has done a great job to make the roads really drivable and beautiful.
Go to Tofino for whale watching or water related sports like surfing and Kayaking. By the way, the water body surrounding Tofino is Pacific Ocean so expect huge waves. This road trip works best with convertibles
