Grenville Channel is a long, well-protected channel along the northern British Columbia coast between the large Pitt Island and the mainland. It is an important shipping lane, and you are likely to see ships of many different types and sizes as you pass through. The shores are mountainous on both sides, with two notable peaks about halfway through, Mt. Batchellor on the east side and Mt. Saunders on Pitt Island to the west. There are a number of Indian Reserves and Marine Parks in the mountains and narrow waterways off the channel.
