The twin lakes of Llynnau Mymbyr sit in the valley below Capel Curig, and in still weather the full mass of the Snowdon Horseshoe — Yr Wyddfa, Crib y Ddysgl, Crib Goch — is reflected in their combined surface. This is one of the classic landscape photographs of Wales, reproduced on postcards since the Victorian era. Experiencing it in person, at dawn or dusk on a windless spring or autumn day, is Experience #24 of the Snowdonia 100.
Finding the Best Conditions
The reflection requires no wind at all — even a light breeze destroys the mirror surface that makes this view remarkable. Dawn is more reliably calm than dusk. Spring and autumn provide the best combination of clear air and windless mornings. In winter, the peaks are often snow-capped and the reflection, when conditions allow, is extraordinary. The viewpoint is simply the eastern end of the lower lake, accessible from the A4086 just west of Capel Curig.

The View Without the Reflection
Even without a perfect reflection, Llynnau Mymbyr provides one of the finest views of Yr Wyddfa available from a valley road. The Pen-y-Gwryd Hotel — Experience #53, the 1953 Everest team's base camp — sits at the head of the valley to the southwest. The Glyderau ridge runs along the north side of the valley. At most times of day and in most weather, this is simply a beautiful place — the reflection is a bonus rather than a requirement.
