West Opabin Trail

Why hike it

The West Opabin Trail is the most view-forward way to reach Yoho’s famed Opabin Plateau. It climbs from the Lake O’Hara basin along Mary Lake, then tackles a steep, rocky talus/boulder slope before spilling onto high meadows, turquoise lakes, and sweeping mountain backdrops. Compared with its eastern counterpart, the west side is more open—translation: bigger vistas, better photos.

Distance and pacing

Most hikers treat this as an out-and-back to Opabin Prospect: about 3.2 miles total and roughly 2 hours, leaving time to linger at viewpoints. If you want variety, ascend West Opabin and descend East Opabin as the Opabin Plateau Circuit (about 3.7 miles total). Strong hikers often extend the day to Opabin Lake or link to other signed routes on the plateau.

What you’ll see

Expect classic Lake O’Hara scenery—glacially carved basins, moraines, and hanging valleys. Wildflower meadows light up summer, and peaks like Mount Hungabee and Yukness Mountain frame the skyline. From the plateau, Opabin Prospect delivers the postcard overlook, while Opabin Lake sits beneath a glacier—dramatic, but strictly look-don’t-touch territory.

Trail feel

The start is civilized—forest and shoreline walking along Mary Lake—then the grade stiffens through loose talus and a boulder field. Footing matters here. Once you crest the grassy cleft onto the plateau, the walking gets easier across rolling terrain and beside tranquil lakes. Stay on established paths; the alpine vegetation is fragile.

Tips, rules, and add‑ons

• Access is limited: reach Lake O’Hara by Parks Canada’s shuttle (advance reservation required) or hike the 11 km access road. Pets aren’t allowed on the shuttle. Daily weather is posted each morning at the Le Relais day shelter—check before committing to higher terrain.
• Want more edge and bigger panoramas? Some hikers connect West Opabin with the Yukness Ledges Alpine Route, but that traverse includes exposure and isn’t ideal if you’re uncomfortable with heights.
• Area rules matter: drones are illegal in Canadian national parks. Fishing and watercraft are prohibited on these lakes. Do not venture onto the glacier above Opabin Lake.

Best time to hike

Late June through early October is the sweet spot, after snow melts and while wildflowers peak. Early season can hold snow and icy patches on shaded talus. Start early for softer light, fewer people, and calmer winds on the plateau.
