Guadalest village clings to a limestone ridge 595 metres above sea level, its castle ruins crowning a natural gateway that once defended inland Valencia from coastal raids. The settlement was fortified by the Moors in the eleventh century, and after the Reconquista it remained a strategic node controlling the mountain passes between Alicante and the interior valleys. A 1644 earthquake and the War of Spanish Succession reduced much of the original fortress to fragments, yet the bell tower of the Church of Our Lady of the Assumption still rises from bedrock, and the narrow entrance tunnel—carved through solid stone—admits visitors one at a time into the upper village. Today Guadalest draws travellers not for military history but for its dramatic topography: the turquoise Guadalest reservoir below, the Aitana massif behind, and a cluster of small museums preserving everything from antique motorcycles to miniature dollhouses. The Algar Waterfalls, thirty kilometres northeast near Callosa d'en Sarrià, are a chain of natural springs that cascade through travertine pools in a river valley shaded by carob and holm oak. The source is subterranean aquifers fed by rainfall on the Bernia and Ferrer ranges, and the water temperature holds steady near sixteen degrees Celsius year-round. The site has been accessible to visitors since the early twentieth century, though formal conservation infrastructure—walkways, railings, and controlled entry—was installed in the 1990s. A five-euro conservation fee supports habitat maintenance and limits daily visitor numbers during peak summer months. The main cascade drops eight metres into a swimming pool open from May through September, and upstream pools connected by shallow channels allow wading in cooler seasons. Altea, positioned between Guadalest and the coast, anchors the itinerary with its whitewashed old quarter and blue-domed church of Nuestra Señora del Consuelo, visible from the coastal highway. The town's economy shifted from fishing to tourism in the 1960s, and its compact hillside core has preserved cobbled lanes and artisan galleries that contrast with the resort developments farther south. Most Guadalest and Algar Waterfalls tours from Alicante allocate an hour for Altea, enough to walk the upper plaza and photograph the coastline from the mirador beside the church. Departures from Alicante typically follow the N-332 coast road before turning inland at Calpe, returning via the same route after six to eight hours. Small-group options limit capacity to fifteen passengers and allow flexible stop durations, while standard coach departures from Alicante and Benidorm run fixed schedules with hotel pickup included.
