There is a historic mission to the west of Lac La Biche and then onto Plamondon. West of here is were the traffic starts get heavy for a awhile. This is part of the highway that connects Fort McMurray to the rest of the world. Grassland is the fuel-up, stop for snack and bathroom breaks before heading north.
There is a steady stream of heavy trucks related to oil production as well as logging trucks headed to the Alpac pulp mill just west of Grassland and down to Boyle. Be patient with the traffic and it will thin out as you venture west to Athabasca.
In Athabasca the water changes from lakes to the Athabasca River. There is a nice park with parking along the riverbank, a good place to rest for a while. There are handy shops across the road for restocking.
On the north side of the river is the Athabasca Golf & Country Club. I was informed it is the 6th most difficult course in Canada. Starting at near the top of the riverbank there are loads of elevation changes along with lots and lots of trees.
