Broad Haven South is a wide sandy beach backed by dunes and flanked by limestone cliffs, located between Saddle Point (on the eastern side) and Star Rock. Just out to sea is the limestone stack of Church Rock. The stream from the Bosherston lily ponds runs along the eastern side, usually creating a large pool ideal for splashing around in, whilst an effusive fresh-water spring can be found on the opposite side near Star Rock. The beach itself is sheltered and generally good for swimming, but rip currents can occur in surf conditions.
Behind the beach are two valleys - the more easterly of the two leads to the Bosherston lily ponds whilst the other (Merepool Valley) is a dry limestone valley with a track leading back to the beach access road. Parking is at a National Trust car park (P&D or attended). Access to the shore is a concrete path with steps, which leads about two-thirds of the way down - the remainder being a descent of the dunes. Getting anything with wheels onto the beach isn't easy, and getting it off again is even more difficult. The car park is listed as a Dark Sky discovery site - a place largely free from light pollution, suitable for some star-gazing at night. Facilities here include toilets, drinking water, cold water showers and usually a refreshment / ice-cream van. Another car park is situated in Bosherston village from where footpaths lead to the beach via the lily ponds - a distance of just under a mile. The village also has tea rooms with outdoor seating and a traditional country pub (St Govan's Inn). It's a good choice for a day out, and there's plenty to explore.
Dogs are allowed at all times. Surf conditions can be good on a big swell especially in winter. The beach is renowned for its board-breaking wedges, when waves from either side of the beach converge. The best conditions occur on mid to high tide, but beware of the rips.
