Routes (1)
- Standard Route — Class 6 (Mars environment; spacecraft & pressure suit required)
The standard ascent of this shield volcano gains roughly 72,000 ft of vertical relief. There are no technical cruxes — the entire difficulty is logistics, cold, and a hard vacuum (or near-vacuum).

Tharsis Montes (western Tharsis rise) — 18.65° N, 226.2° E.

NASA Mars Trek
Conditions — Olympus Mons
Thin carbon-dioxide air (about 600 Pa at the datum, far less at these summits), daytime highs near −20°F that plunge below −150°F at night, and planet-girdling dust storms. A pressure suit is mandatory. Summit air pressure is only ~72 Pa. The volcano is so wide that its base curves below the horizon — you can't see the whole mountain from anywhere on it.
Summit: 72,000 ft (~22 km base-to-peak (up to ~26 km / 85,000 ft on its west scarp)).
