What it is
A high, wind‑scoured mountain pass between the Wiwaxy Peaks and Mount Huber, Wiwaxy Gap tops out around 2,530 m and anchors the classic Lake O’Hara Alpine Circuit. Most hikers grind up steep switchbacks from the lake, tag the Gap, then traverse the Huber Ledges toward Lake Oesa.
Why go
The views are outrageous: turquoise Lake O’Hara far below, spiky ridgelines all around, and sightlines toward big names like Mt. Biddle, Hungabee, and Yukness. It’s the kind of high-alpine drama that makes the O’Hara basin so famous, concentrated into one shoulder-burning climb and a lofty perch that feels properly wild.
The route feel
Expect a sustained, steep ascent on rocky, sometimes loose tread with short exposed sections. The descent/traverse on the Huber Ledges is exactly what it sounds like—narrow ledges cut into cliffy terrain. Confident hikers love it; anyone uneasy with heights won’t. Beyond the Gap toward Wiwaxy East Peak, the beaten path fades and route‑finding + hands‑on scrambling become the name of the game.
What you’ll see
- Aerial views of Lake O’Hara and, in clear conditions, glints of Lake Oesa
- Sheer quartzite walls, scree, and open alpine meadows on the approach
- Prime photography angles throughout the Gap and ledges
Wildlife
This basin is known for mountain goats, marmots, and pikas, with occasional bears moving through. Stay alert, give wildlife space, and follow standard bear‑country practices.
Know before you go
- Access to the Lake O’Hara area is tightly limited and requires advance reservations; that’s part of why it feels pristine.
- Paint blazes and cairns help, but fog or lingering snow can complicate navigation—carry a map or GPS.
- There are no facilities at the Gap—no water, toilets, or shelter—so plan to be self‑sufficient.
Best time to visit
Start early for cooler temps, steadier footing, and flattering light over O’Hara. Late season (after the bulk of snow has melted) is the most straightforward; early season can mean snow/ice on ledges. Wind is common at the pass, so bring layers. Even with the access limits, mornings are calmer and less social than mid‑day.
Gear and prep
Sturdy boots and trekking poles help on the steep switchbacks and loose bits. Pack layers, rain shell, sun protection, plenty of water and calories, and a navigation aid if you’re continuing beyond the Gap.
Pros
- Jaw‑dropping panorama over Lake O’Hara and surrounding peaks
- Key high point of the Lake O’Hara Alpine Circuit via Huber Ledges
Cons
- Steep, exposed ascent with loose rock and ledgy sections
- No amenities; wind and lingering early-season snow can add risk
Tips
- Start with the Gap first to tackle the steepest climb while fresh.
- Bring trekking poles—steep switchbacks and ledgy traverses add up.
- Carry layers; the pass is often windy and noticeably colder than the lake.
- Watch for blazes and cairns, but bring a map/GPS if continuing past the Gap.
- Reserve access to the Lake O’Hara area well in advance or you won’t get in.
