The distinctive profile of Yr Eifl is a key part of the Lleyn landscape. The peaks really stand out from a distance; particularly when viewed from the beaches along the south west coast of Anglesey. The pyramid-like summits also dominate the landscape when viewed from the south and west. The main Yr Eifl summit is 564m, but this seems to be exaggerated by its closeness to the coast – the drop off from its northern satellite peak into the sea is very severe indeed.
A circular walk from Trefor takes you along the coastal footpath above the shale sea cliff of Trwyn y Tal, before striking upwards by the side of the large quarry to reach the summit area. The summit vista is stunning and well worth the effort required to work up through all those contour lines. A detour to the nearby hill fort on Tre’r Ceiri is a must; here you will find dry stone walls and hut circles which date from the late Iron Age.
A much less strenuous route option is to start from Llithfaen on the southwest side of the hill. This has the advantage of a 200m high starting point, but on the downside it does miss out on some of the dramatic landscape features on the Trefor side.
There is a car park (and toilets) close to the harbour in Trefor. There is also some roadside parking possible ion the eastern side of Llithfaen.
Mostly good tracks and footpaths, but some rough terrain in places.
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.
