Medicine Lake is Jasper’s disappearing act. Fed by the Maligne River, the lake fills in summer, then drains away in fall and winter through sinkholes into a vast underground karst system—water later resurfaces down-valley at Maligne Canyon. It’s a rare, textbook example of a “losing stream” on a grand scale.
This valley is a reliable wildlife corridor. Keep your eyes peeled for bighorn sheep, elk, moose, and black bears along the shore and roadside. Bald eagles nest in the area; occasional closures can protect nesting sites—respect any posted notices.
Located along Maligne Lake Road about 20–25 km southeast of the town of Jasper, Medicine Lake is an easy pull-over stop. You’ll find roadside parking areas and viewpoints with interpretive panels explaining the geology. Don’t expect services here—no food, store, or washrooms at the lake itself; plan your pit stops at Maligne Canyon or Maligne Lake.
Medicine Lake isn’t a typical lake—it’s a temporary reservoir atop a perforated limestone floor. As inflow wanes each year, water drains into underground caves and sinkholes, making the shoreline shape-shift with the seasons.
Yes—especially if you’re already driving Maligne Lake Road. It’s less busy than Maligne Lake, the scenery is superb, and the geology story is one-of-a-kind. Just calibrate expectations if you visit in late season when the “lake” looks more like a river on a wide, muddy bed.
