The best view to be had of these two lakes is from the Crib Goch, and they will be a long way below you.

Lliwedd is a wonderful secondary peak, and a climbers playground.

A wonderful route, but not for the fainthearted or ill equipped. Also best avoided in high or gusty winds.

Magnificent peak that forms part of the Snowdon Horseshoe. Huge north west facing cliffs and an airy double summit.
