The three peaks of Yr Eifl: Garn For, Garn Ganol and Tre'r Ceiri

 Yr Eifl is the highest point on the Ll?n Peninsula. There are three peaks - Tre'r Ceiri (485m), Garn Ganol (564m) and Garn For (444m). Tre'r Ceiri has one of the best examples of an Iron Age hill fort in northern Europe.

Garn For has been extensively quarried and granite from here has been used to pave streets in London and as curling stones used in the Olympics.

The best place to start any walk on the hills of Yr Eifl is on the road to Nant Gwrtheyrn. There is a car park, just before the road starts to run downhill towards the National Language and Heritage Centre.

From the car park, walk along the track you can see working its way across the side of the hill and you will come to Bwlch Yr Eifl, between Garn For (with it's quarry) and Garn Ganol, the highest point on the peninsula. From here you can choose whether to do Garn For before continuing or just to go straight and walk up Garn Ganol.

Walking up Garn For is quite tricky in a couple of places, so be careful. Walk up around the radio mast and then continue up to the cairn on the summit.

The walk up to Garn Ganol is in three stages, the first grassy slopes, then rocky, lumpy ground, and finally steep loose rocky slopes near the summit. Paths are sometimes a bit difficult to follow and you may find you come down a different one than the one in which you climbed up! The views are, needless to say, spectacular from the top.

From the summit you can walk back down to the car park or come the way you came. If you wish, you can continue down to Tre'r Ceiri. The pathway takes you through lots of heather and there are rocks under foot so care is needed in places. Once to get to the summit of Tre'r Ceiri you will notice that you are surrounded by the iron age hill fort.

From Tre'r Ceiri a walk along the south-western slopes of Yr Eifl will take you past Caergribin, a large rock outcrop. Beyond this continue to the car park.

From the car park, you can walk straight up to the summit of Garn Ganol (the highest peak) by taking a path which branches off to the right at the start of the track mentioned at the start above. This path runs around the southern side of the hill and, although it is still steep, is less rocky than the other route until you reach the summit.
