Huandoy or Tullparahu is a mountain located in Peru. It is the second-tallest peak of the Cordillera Blanca section of the Andes, after Nevado Huascarán. These two peaks are rather nearby, separated only by the Llankanuku ravine with its Llankanuku Lakes (3,846 m).
It is a snow capped mountain with four peaks, the tallest of which is 6,395 m arranged in the form of a fireplace. The four peaks are each over 6,000 m, and are:
- Huandoy Peak (6,395 m)
- Huandoy-West (6,356 m)
- Huandoy-South (6,160 m)
- Huandoy-East (6,070 m)
It was first climbed in 1932 by a German party. The ascent from the Llankanuku Lakes was first climbed in 1976.
The original name of the mountain is Tullparahu, which comes from Quechua tullpa ("stone fireplace") and rahu ("ice"), so Tullparahu means "snowcapped mountain in shape of a fireplace."
It is part of Huascarán National Park.
