Get or rent wheels for the canoe, They strap on in the middle of the canoe on the portages and your canoe becomes something like a wheelbarrel balanced in the middle. A lot easier than carrying. While paddling, wheels are up on top of gear. Made out of bicycle tires. Get in touch with Jim at Bowron Lake resort or Lotar at Beckers Resort, or Sandy at Bear Creek Merchantile Store. I'm pretty sure they all rent this rig.
Bug Dope a must before Sept frosts. Be prepared for rain or snow most months of the year, but can be blistering hot also. Lakes tend to kick up with wind in afternoon on sunny days.
Fishing is great but special regs apply. There is a reservation system, get in touch with parks branch pronto if he does not have one. It may be too late already.
