We stopped here for gas and water. Hinton is about an hour west of Edson (with little in between) and 45 minutes to an hour from Jasper, so it is a convenient place to stop.
This is a well-stocked little store with decent restrooms.
The only minor issue I had was with the gas. Most places just let you fill up after providing a credit card. Some places make you pay the cashier in advance, which is less desirable. Here, they make you estimate what tier of gas you'll need ($10 / $20 / $30 / etc.). Given that I was driving a rental car in Canada, where fuel prices (and volumetric measures) are different, it was a real challenge to figure out. I lowballed it and under-filled without having a remaining $ balance, though. I just found this very inefficient.
For comparison, another Canadian station later in our trip instead had multiple tiers of fill-up but listed them as 'up to $100', etc. This was much more convenient. read more
