The Fuentes del Algar, fed by the Algar River, were declared a Protected Wetland Area in 2002, preserving 15,000 square metres of travertine formations that date back millennia. The springs discharge an average of 1,200 litres per second year-round, carving a series of pools and cascades through limestone terraces in the municipality of Callosa d'en Sarrià. Coupled with Guadalest, a fortified village perched 595 metres above sea level on a limestone outcrop, the pairing delivers both geological heritage and medieval architecture within a single half-day circuit from Benidorm. Guadalest's strategic elevation made it a Moorish stronghold until its conquest in 1245, and its castle ruins — remnants of a fortification rebuilt after the 1644 and 1748 earthquakes — still anchor the village's skyline. Below, the turquoise Guadalest reservoir, completed in 1953, supplies irrigation to the surrounding Alicante valleys. Narrow stone streets lead to eight small museums, including collections of vintage cars, dollhouses, and medieval torture instruments, each operated independently by local families. The village receives approximately 2.3 million visitors annually, making it one of Spain's most visited inland sites despite a resident population of fewer than 250. At Algar Waterfalls, a 1.5-kilometre boardwalk trail winds past five main cascades, the tallest reaching nearly 30 metres in height. Native vegetation includes willows, oleanders, and Mediterranean hackberry, sustained by the constant moisture. Visitors access designated swimming zones in the lower pools, where water temperatures hold steady at 16-18°C throughout summer months. The site's conservation fee, implemented in 1994, funds maintenance of the wooden walkways and seasonal lifeguard staffing during peak periods from June through September. Guadalest and Algar waterfalls tour from Benidorm itineraries typically allocate two hours for the village exploration and 90 minutes for the waterfall circuit, with departures scheduled to reach the springs before midday heat. Jeep-based variants navigate the inland CV-70 and CV-715 mountain roads, offering elevated views of terraced almond orchards and citrus groves that define the Marina Baixa agricultural landscape. Standard coach tours depart Benidorm's Avenida de Europa and include round-trip transport, entrance to both sites, and multilingual guides. The combined route covers approximately 80 kilometres, with a total journey time of five to six hours door-to-door, positioning it as the most efficient means to access both landmarks without private vehicle rental.
