Mauna Kea 29er

Routes

• Summit Road — drive to ~13,800 ft
• Humuʻula Trail — ~6 mi on foot

The catch: only the top ~13,800 ft is above water. The other ~19,700 ft of this mountain is underwater, so nobody actually climbs the full ~33,500 ft. Still counts.

Trip Reports

Plenty of visitors reach this summit — most of them never realizing they are standing on Earth’s tallest mountain. Post your report!

Conditions — Mauna Kea

Actual weather! Wind, snow, and breathable air (less of it the higher you go). Comparatively hospitable — and, by solar-system standards, comparatively tiny. The only peak here you can summit by road — bring a jacket, not a spacesuit.

  Summit: 33,500 ft (~10.2 km from the Pacific seafloor).
