Mynydd Mawr

Mountain & Hill Walks

The isolated peak of Mynydd Mawr gives an ideal short day out with the choice of a straightforward up-down trip, or if visibility is good, a circuitous route looping south from the Snowdon Ranger YHA, before gaining the summit and dropping down through the Tros-y-gol forest. The second option is more satisfying but does involve a significant amount (3.5km) of road walking.

If you don’t fancy the road walking then it is possible to start in Rhyd Ddu and follow a track through the forest to connect with the path leading out onto the hillside.
Steep walking gains the top of Foel Rudd, and then an undulating ridge is followed, with splendid views of Craig y Bera’s towering buttresses. From the summit the circuit route descends to a path which runs round the lip of Cwm Du. Some pathless terrain must be navigated to reach a path leading to the forest. Once in the trees a track will take you back to the main road. From here all that remains is a 2km road stomp adjacent to Llyn Cwellyn.

Conditions:

This is mountain terrain so always Prepare Well and Know Your Limits. During the winter season, typically from late October to April, there is a high probability that snow and ice will be encountered under foot. In these conditions ice axe and crampons are essential.

Approach:

The Mynydd Mawr circular walk is best started from Snowdon Ranger YHA on the A4085. Rhyd Ddu also provides a good starting point for an ascent.

Safety & Access

Enjoy the Mountains Safely. Here are a few words of advice from Snowdonia’s Mountain Safe Partnership.

1. Prepare Well
have the right equipment with you for the best and worst-case scenario! You’ll need a map and compass, torch, food and drink, whistle, first aid kit and a fully charged mobile phone.

2. Have the latest weather and ground information.
Check the Met Office Mountain Weather forecast for Snowdonia before you set out and be prepared to turn back if the weather worsens – the mountains will still be here for you to enjoy the next time you visit.

3. Dress appropriately
the weather and temperature can change dramatically between the foot of the mountain and the summit. You’ll need strong walking boots, several layers of clothing including warm ones, gloves, a hat and waterproof jacket and trousers.

4. Know where you're going
Plan your route before setting off and ask for local advice. Have a map and compass and know how to use them and choose a route which is suitable for you and your group’s experience and fitness level. Find out how long it should take and when it gets dark.

5. Know your limits
whilst being very enjoyable, getting out into the mountains can be hard work – challenge yourself but be aware of the fitness levels, and experience of the group as a whole – not just your own.
