SNOWDON - This is not the recommended loop. The recommended route descends down the Rangers path which is more rideable, less technical and not as exposed but still black grade and fun. See MBWales.com for details on the classic route.

This route descends the Rhyd Ddu path which traverses an exposed knife edge ridge not recommended in high winds. The riding is very technical.

Be prepared for a mountain day out. The weather and temperature at the top can be very different to the valley. A comfortable +10 degrees in Llanberis will be 0 degrees on the summit. Factor in wind chill from high winds and it can feel like -10 degrees.
Take a map and compass and know how to use them. If the cloud level is down, visibility can be reduced to a few meters. Finding the descent can be very difficult and you could end up on steep, loose dangerous ground. There are big cliffs on all sides of the mountain and fatalities happen every year.

IMPORTANT! Please adhere to the Snowdon Voluntary Cycling Agreement. No riding on Snowdon between 10am & 5pm, from 1st May to 31st September.
This is to avoid any collisions or conflict with walkers.
Snowdon becomes so busy and the paths so full of walkers that it’s no fun and can be very frustrating.
During the restrictions, an early ascent to watch the sunrise, or an evening ascent for the sunset can be amazing and with most of the walkers off the mountain, the descent is much more fun.
