I just hiked up Black Tusk from the microwave towers and thought it was fantastic. It took us around 2.5 hrs to get to the top, it was tough because you are so far above sea level, the air is quite thin. If you are not a tree hugger I would suggest that you talk to a local with a 4*4 or rent one and get directions to the service road up. It is still a tough hike, but well worth it. And for the real enthusiasts you can start down near the valley. You should give yourselves at least two days as it is, so I have been told 36 kms round trip. Do it, it is well worth it.
