The Great Orme: Lower Pen Trwyn

Apologies for the multiple posts today but there’s lots to post about since returning from Wales!

I hadn’t climbed on Lower Pen Trwyn (LPT) before but would certainly go back. In terms of the Climbing LPT has some really good routes across the grades and has the feel of sport climbing elsewhere in Europe, especially if the sun is out! Could The Orme be the Welsh answer to Kalymnos?

The approach is pretty simple (steep start) with some good geology to maintain interest on the way in. The following photos and thoughts are by no means an exhaustive study, and were captured in a passing by type manner with the intention of inspiring climbers to look around them on the way in to LPT.

Sediments onto of the limestone on the approach to Lower Pen Trwyn. Presumably these are recent sediments sourced from the limestone above on the Orme, but this does not explain why there is such rapid variation in roundness and sorting between layers. Ideas?

Presumably the sediments above the limestone are relatively recent, and are sourced from the limestone above on the Orme? This short transportation distance however does surely not provide a satisfactory explanation as to why there is such rapid variation observable in roundness and sorting between beds?

Climbing wise Under the Boardwalk stands out as a real classic of the crag, proving to be a tricky little number requiring a sustained effort right till the end, but the crag contains abundant quality climbs. At the far right end there are several ‘easier’ sport routes in the F6a(ish) range with Beauty is Only and Skin Game being good fun.

Oh and remember that LPT is tidal, and accessible apart from about three hours either side of high tide. Its also worth noting that the 1st bolt on most climbs is pretty high (due to the tides).
