Garn Boduan is a prominent hill which sits above Nefyn on the north coast of the Lleyn Peninsula. It is only 280m high but the summit provides a splendid vantage point from which you can soak up the wonders of the Lleyn landscape, from Yr Eifl to the north east and across the southern flatlands of the peninsula and back round to Carn Fadryn.
Although not particularly apparent from below, the summit plateau is quite extensive. This unique geographical feature made it an obvious place of retreat during wars or invasions. There are widespread remains of an Iron Age or Dark Age provenance to be found here. The hill fort feature is over 10 hectares and within it hundreds of hut circles can be seen.
A straight up and down ascent will suit those lacking in time. However, if you care to linger a while, a more satisfying circuit can be done by dropping off the south eastern flank and looping round to the north. Here you can cut back across the wooded slopes of Mynydd Nefyn.
Nefyn is the best starting point; there is a small car park in the centre of the village.
Mostly good footpaths, although rocky 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.
