Rhosneigr Beach (pronounced ross-nee-ger) is a sandy beach to the west of the town, and is a popular location for sailing, wind / kite surfing, canoeing and surfing. Access to the beach is down one of several roads which lead right down to the shore, and dogs are allowed at all times. A small car park and toilets are situated near the library and plenty of roadside parking is available, mostly at the northern end of the village. Facilities include cafes, beach / surf shops, stores, pubs and a rail station (about ¾ mile away). Conditions for surfing are best around mid-tide, but drop off towards the high. Swimming is generally safe, but dangerous rip currents can occur in surf conditions. The name 'Rhosneigr' translates as 'Viper moor'.
To the south are several small rocky islets just a few hundred yards from the shore, some of which have their own tiny beach. At the northern end the stream of Afon Crigyll emerges onto the beach, and the shore to the west of this is known as Traeth Crigyll. This is a wide sandy beach backed by low dunes, and can be quite windswept as the dunes offer little shelter.
