St Brides Haven is at the end of a short no-through road, signposted from the B4327 Haverfordwest to Dale road. A (free) car park is situated on grass in front of St Brides church. There are toilets here and a building called the Pump House. Access to the beach is down a short track onto the shingle.
The beach looks out onto St Brides Bay and is made up of sand and pebbles flanked by low cliffs of sandstone and mudstone. Just behind the beach a grassed area has a small stream running through it and some picnic tables. It's not the kind of beach you'd want to spend a day at, but a pleasing place to relax on a summer's evening.
The beach is good for swimming and popular with sub-aqua divers, being very sheltered and suitable for novices. A good footpath leads south from the churchyard towards Marloes and Musselwick, from where you can take the coastal path back to St Brides.
