South Bishop Lighthouse on Emsger

The South Bishop Lighthouse sits on a rocky outcrop miles off the Pembrokeshire coast, a proper maritime sentinel that's been warning ships away from these treacherous waters since 1839. You won't be climbing up inside it - the lighthouse is only accessible by boat, which means it's more of a spot-the-landmark activity than a full visitor experience. What you do get is a cracking photo opportunity from the water, especially on clear days when you can make out the red and white stripes from considerable distance. The approach by boat gives you a sense of why this thing was needed in the first place; these are genuinely dangerous waters, and the lighthouse earned its keep many times over.

It's best suited to maritime history enthusiasts or anyone doing a proper boat tour of the Pembrokeshire coast from nearby Ganol. Kids might find the boat journey itself more entertaining than staring at a lighthouse from a distance, to be honest. Allow a couple of hours if you're taking a dedicated boat trip, though most people encounter it as part of a wider coastal excursion.

If you're based at Rhosson Ganol Caravan and Camping Site or the excellent Rhosson Campsite (both handily close by), you're well positioned for coastal exploration. The lighthouse works best as part of a broader day out rather than a destination in itself - pair it with the dramatic cliffs and walking trails that make this stretch of Pembrokeshire worth the visit. Check locally in Ganol for current boat operators, as access and timing depend entirely on sea conditions and available tours.
