The north beach at Aberystwyth reaches from Constitution Hill at its northern end to the town's Victorian pier at the other. The beach is mostly sandy, with the sand on upper part of the beach being grey and gravelly. It becomes rocky at both ends and is backed by a promenade and the main town area. A dog ban operates between the north side of the Landing Stage and the extreme northern end of the beach at Craig Glais from 1st May to 30th September. RNLI lifeguards patrol during the school summer holidays. There are all the usual facilities here including cafes, toilets, showers, drinking water, pubs, shops, a children's paddling pool and a Tourist Information centre. There is limited roadside parking along the promenade, and further car parks and street parking in the town. Aberystwyth rail station is approximately 400 yards from the beach and is the terminus of the narrow gauge Vale of Rheidol railway as well as British Rail's Cambrian Coast line. Constitution Hill is 374 feet high, and has a cafe and the world's largest camera obscura as well as extensive views of Cardigan Bay. The ascent of the hill can be made either on foot or by cliff railway. The coast northwards to Clarach Bay is mostly rocky and backed by cliffs of mudstone and sandstone with a prominent sea stack (Cormorant Rock) about 400 yards along. Walking to neighbouring Clarach Bay along the shore is possible, but due to risk of being cut off this should only be attempted on a falling tide.
