Crag features

Porthclais is the harbour for St. David's and has been the main route into the city for pilgrims, saints and traders for centuries. It is one of the more popular climbing venues with good quality sandstone routes, mostly in the lower grades.

Approach notes

There is ample parking and public toilets in the old gas works site 100m inland just beyond the boat park.

Rockfax App

Available in the Rockfax App

The Rockfax App brings together all the Rockfax climbing information with UKC logbooks and presents it into a user-friendly package for use on Android and iOS devices.



This new app version of the Pembroke Rockfax has been significantly updated with 350 extra routes, new geo-located maps and updates to the existing information. The print guide from 2009 had 650 routes and this new app package has nearly 1000! The update includes many easier routes plus extra lines at the main crags covered in the book. It also has extensive deep water soloing coverage with the majority of the crags from Mike Robertson's 2007 Deep Water book added to the mix.
More info


This book from 2009 covers all the classic routes on the most popular crags of Pembroke. It covers the beautiful slab climbing around St. David's and all the best crags of Range East and the Lydstep areas, as far as Mother Carey's Kitchen. The range and variety of routes is enough to keep any climber happy; from those leading moderate grades keen to have a look for the first time, all the way to those who have developed lifelong obsessions for the place!

Statement from BMC website: There is a very loose area of overhanging rock between the Grey Slab and Red Wall. The National Trust are currently (Sept. 2013) working on this to remove a hazard and this will affect access to several routes for a short time (see details on site). See info below from NT. "On 7th and 12 August steps were taken to remove a dangerous section of unstable rock near Grey and Red wall, to the east of the harbour entrance. There is still further work needed to completely remove the boulder 'bridge'. Temporary signage on site diverts walkers around the affected area and also details climbing routes that are affected."

17-11-13 The loose rock bridge has now either been taken down or has fallen down as there is nothing but a sheer drop !!

Block isn't going to come from the wall anytime soon - just be aware of it.
Matt88 - 13/May/13
Just a heads up - theres a wobbly block in the all lines engaged/ sea rider area just above the diagonal crack, looks like a great hold till you grab it! doesn't look like it can be pulled off at the moment as i gave it a good shake - will have a closer look in two weeks and see

The 'fake boulder' has been placed, with the support of the National Trust, National Park, the BMC, Pembrokeshire Outdoor Charter Group and local climbers, amongst others. It replaces a mass of crap, rusty stakes with the aim of cleaning up the site and providing a long term belay solution.
Steve Quinton - 15/Jul/04
When i was there early this summer the belay stakes had been removed and replaced by a 'fake' boulder! While great for 'The Crack' and other routes on the left of the purple slab, belays for those on the right are now difficult to arrange.

Nice location, can get busy but, worth a visit.
