I have been travelling to Bella Coola and then on to Ocean Falls/Bella Bella/Seaforth Channel/Milbank Sound/Hakai Pass/Namu Harbour/Burke Channel/Restoration Bay etc. for the last 10 years. I try for 4 trips a year (in week ea. June, July, Aug. Sept)
We just got back Sept. 8 from another successful trip. I live in Cache Creek so it is just too easy to travel to Bella Coola rather than travel to Van. then take the ferry and then bash all the way up to Port Hardy and then you are still 6-7 boat ride up to Shearwater.
I have taken to leaving my 24 ft. Searay in Bella Coola rather than drag it back and forth but than is just a convenience and cost thing. The big cost was brake shoes and bearing sets for the boat trailer because I just have surge brakes on the trailer. If you have a proper trailer brake control that works independently from the truck life would be easy. If you take it slow and easy and your equipment is in reasonable shape there is no problem. The drive is relaxing as traffic is very light. There is only 60 odd km. of gravel left (west of Anaheim to the bottom of the hill) the whole "hill" portion of the drive took 20 min. to climb last month....going down would probably take twice as long. Total drive time from Cache Creek to Bella Coola is 7 hrs. No ferry fees.
The fishing in the area has always been very productive and the pressure is very light. It just seems to be a much more pleasant area to fish. Long distance runs should be done in the a.m. if possible and there are stories of rough water and tough goin' but that stands for just about everywhere on the west coast. Once you are at Shearwater you can fish all over the place always in protected water.
We most often sleep on the boat as there are many excellent hide-outs close to the action so we go back to town (Shearwater or Bella Bella) every 2 or 3 days. If staying on the boat is not for you Shearwater has rooms and there are B&B's, rooms only, and cabins for rent on Denny Island.
PM me if you would like for specific recommends on lodging or fishing locations.
