Walk this way: Yr Eifl, Gwynedd

Route: From Llithfaen , walk east along the B4417 to a left turn, opposite a chapel. Follow the lane uphill to open moorland. Head left from the fork in the track along the Lleyn Coastal Path (LCP). Stay on the main trail, left of Caergribin hilltop, but after the kissing gate turn right onto a narrower path to the summit. Take the path north off Caergribin to rejoin the LCP. Turn right here onto the latter and continue to the south-western entrance of Tre'r Ceiri hillfort. Follow the path to the summit. Continue in the same direction, to the perimeter wall then turn left to the gateway. Go through to exit the enclosure and bear right along a path that swings left towards the pass below. Carry on, keeping right when the trail forks. The route to Yr Eifl's summit is obvious. Follow the trail south-west from the summit. Past a stone wall, it bends west to the junction of a forestry road and quarry track to the north of which lies a car park. Keeping this to your right, head past a row of houses and on for 650 yards to Llithfaen.

Why go? On the Lleyn Peninsula in North Wales, this trio of shapely hills, known collectively as Yr Eifl (‘the rivals' or ‘the fork' in Welsh), rise abruptly from the rocky coast against an epic backdrop of churning Atlantic surf. There are stupendous views from the top of the highest hill, Garn Ganol, with lines of sight connecting the mountains of Ireland with those of the Lake District - not to mention the Snowdonia range inland.

How long will it take? Around three hours.

Stamina required? Plenty - there are three short but steep ascents and descents.

Refuelling options Surely one of the best-situated pubs in Britain, the Ty Coch Inn (01758 720498, www.tycoch.co.uk) is at the head of a sandy bay just up the coast from Yr Eifl. Only accessible on foot.

What else is there to see? The walk takes in the hilltop citadel of Tre'r Ceiri, inhabited during the late Bronze Age and the end of the Roman occupation from 200-400AD. It is from this latter period that the 150 or so dry-stone hut circles within the fort date.

Wildlife highlights? The North Lleyn coast is home to choughs, razorbills and guillemots.

And for kids? Make a detour to Cadwaladers Ice Cream Café - in either Criccieth or Pwllheli - and treat them to some old-fashioned desserts (www.cadwaladersicecream.co.uk).

Where to stay The Nanhoron Arms Hotel in the historic village of Nefyn, a few miles south-west of Llithfaen, is well placed for nearby beaches (01758 720203, www.nanhoronhotel.com).
