Clearwater is a lovely quiet little town to spend a night or two either on your way to or from the Rockies, as a stopping point between the parks and Vancouver. I spent a night here on the way back. There some great little diners, as well as some lovely hikes, as well as a waterfall.
B&B I used in Clearwater
The walk to Spahats Falls
Spahats Falls is the perfect activity if you are in Clearwater for a short stay. It's a short drive from the town centre to the park, and an easy walk from the car park to the waterfall.
