Montaña de Arena is a beach near San Bartolomé de Tirajana in the Canary Islands, listed for naturist use without confirmed designated status. It has a sandy surface and faces open Atlantic water where waves and currents can occur. The setting is generally quiet, with low visitor numbers and wide spacing between groups on the sand. There are no developed facilities, so visitors need to carry drinking water, sun protection, food and other supplies, and take all rubbish away with them at the end of the stay. Access is on foot over sandy ground from nearby coastal access, and the uneven sand can make walking slow, especially in warm midday weather, so accessibility is limited. Sensible footwear, a clear plan for the return walk and a conservative approach to swimming are practical for this open shore. Weather is mild and dry for much of the year, with the May to October period offering consistently warm and sunny conditions for time on the sand. Sun exposure is high and there is little to no shade or shelter, so a parasol, hat, sunscreen and extra drinking water are important throughout the day. The sea is open and changeable from day to day. Weak swimmers should stay in shallow water, avoid going far out when waves are present and keep attention on currents near the shore. Because the location is quiet and isolated, mobile reception, help and supplies should not be assumed to be available. Tell someone your plans, keep valuables minimal, watch personal safety on uneven ground and allow enough daylight for the slow walk back over sand.
