ALT 4,120M Ridge Traverse — Live Render
Serac Expeditions

Guided ascents on the world's great mountains.

Serac has spent three decades building the logistics, permits, and mountain sense to guide climbers safely up the world's most demanding peaks — and to know, just as importantly, when to turn a team around.

Terrain & Ice

Reading a mountain before you trust it.

Every guided route in the Serac catalog begins with years of terrain study — seracs, bergschrunds, and windloaded slopes mapped and re-mapped across seasons before a client ever clips into a rope on it.

The decision that matters most is the one to turn back.

“We had four hundred vertical meters left and eleven hours of weather window. We turned around anyway — the barometer was falling faster than the forecast said it should.”

Every Serac-guided expedition builds in at least one planned contingency day, and every lead guide has the standing authority to call a summit push regardless of client expectations or sunk cost.

Logistics

What actually gets you up and down safely.

01

Acclimatization Schedule

Every itinerary is built around measured ascent rates, not the calendar — rest days move if bodies need them to.

02

Fixed-Rope Protocol

Technical sections are rigged and inspected daily by route-fixing teams ahead of client rotations.

03

Oxygen & Medical

Supplemental oxygen caching and a Wilderness First Responder on every high-altitude rotation.

04

Weather Routing

Independent meteorology briefings cross-checked against on-the-ground barometric readings twice daily.

Lead Guides

The people who make the call.

Anders Bricmont

Head Guide, Himalaya & Karakoram

Noa Fennimore

Head Guide, Andes & Patagonia

Tomas Reyk

Alpine Operations Director

“The most conservative outfit on the mountain, and the one with the best safety record to show for it.”

Alpine Journal

“They turned us around eight hundred meters from the summit. It was the right call, and it's why we're still climbing.”

Client Dispatch, 2024

“Serac's terrain archive is the most thorough route documentation outside a university glaciology department.”
