Sand Bay (sometimes known as Kewstoke Beach) is a sheltered bay of medium to coarse sand with thick mud lower down the beach. Signs warn of "Sinking mud". At the northern end, the headland of Sand Point shelters an area of saltmarsh which has been colonised by cordgrass. The beach is backed by a wide bank of blown sand, which is home to sea buckthorn, teasels, some impressive tree mallows, plenty of driftwood and three old WW2 pill-boxes. The sea here is usually a muddy brown colour.
There are three free car parks just behind the beach, and the appropriately named Beach Road runs along the entire length of the beach, with holiday parks and a row of bungalows on the landward side. A half-hourly bus service runs from Weston-Super-Mare with the centre car park being the terminus. Open-top buses run this route in summer.
Dogs are allowed all year round. Facilities include toilets, a pub and plenty of benches along the front. The Sand Bay Tea Rooms (near the centre car park) has indoor and outdoor seating, and serves light meals, teas, sandwiches and cakes.
