As you snake your way through the mountains on your way to Jasper, there are a few places worth stopping at. Sunwapta Falls and Athabasca Falls , closer to Jasper, are both worth a stop. The latter is the more voluminous and is at its most ferocious in the summer when it's stoked with glacial meltwater.
A less-visited spot is idyllic blue-green Horseshoe Lake , revered by ill-advised cliff-divers. Don't be tempted to join them.
At Athabasca Falls, Hwy 93A quietly sneaks off to the left. Take it. Literally the road less traveled, this old route into Jasper offers a blissfully traffic-free experience as it slips serenely through deep, dark woods and past small placid lakes and meadows.
