I hope you have lots of time! Rent a car, for sure. There are so many things to see. Make sure to take the old Island Highway as much as you can to see everything along the coast. Bamfield is a must if you can get through, although the road was really rough last time I was there. See the old whaling town out of Port Hardy. Basically, take any road you can drive on and you will not be sorry. There's a LOT to see.
