Went through it once to get to Ireland and to Tenby a few times – crazy when I lived in South Wales for the first 21 years of my life. I’ll be trying to convince our friends for a trip back to that corner of the Fatherland Zilog – where did you go?
Stayed on a caravan park near Narberth that had a few secluded “glamping” (basically a wooden cabin thing, no actual camping involved!) units at the back with awesome views & private hot tubs! Was a case of just randomly picking somewhere but turned out to be a decent location as it’s reasonably central and nowhere else in Pembrokeshire is more than a 30-40 min drive away max. Plus it was really nice!
Took bikes but didn’t end up doing that much cycling. Not sure it’s that great for MTB – had a nice but non tech ride in the Preseli Hills and rode the only (very short!) section of the coastal path that’s a bridleway. Lots of nice road/gravel riding around the country lanes etc. There is a NCR that runs all the way through Pembrokeshire.
Loads to do though – great walking, beaches (loads of deserted ones as a lot of them are inaccessible by car), decent pubs/beer/restaurants if you know where they are. Day trip to Skomer was a highlight as there are about 30k puffins on the island at the moment!
Saundersfoot & Tenby are nice (we walked between the two along the coastal path which was a good walk), a bit touristy but way less than say Newquay in Cornwall.
