Embalse de Alloz is a reservoir situated in the municipality of Abárzuza in the Estella-Lizarra comarca of Navarre, Spain, approximately 55 kilometres west of Pamplona via the A-10 motorway. The reservoir was formed by damming the Salado River and covers a substantial surface area, making it one of the most popular inland water destinations in central Navarre for swimming, water sports, and summer recreation.
The water is comparatively warm by late June, as the reservoir's relatively shallow profile and south-facing orientation allow the surface to heat efficiently through spring. The colour tends to a vivid turquoise-green in clear weather, contrasting sharply with the dry limestone hills and patches of scrub oak that frame the shoreline. The main accessible bathing area occupies a gently shelving gravel and pebble shore that allows easy entry into the water without abrupt depth changes.
Alloz is particularly popular with windsurfers and kayakers because the surface is broad and exposed to the prevailing south-westerly winds that funnel through the valley. Equipment hire has been available locally in summer seasons, though visitors are advised to confirm availability in advance. The reservoir also attracts anglers along its quieter northern margins, and the surrounding hillside trails offer walking options for non-swimmers.
Several picnic zones with tables and shade trees are located near the main access point, and free parking is provided at the site. No permanent restaurant operates at the reservoir itself, so visitors should bring provisions or plan a meal stop in the town of Estella, about 12 kilometres to the south-west. A car is effectively required to reach Alloz, as public transport connections to the reservoir are limited.
The landscape around Alloz represents the transitional character of central Navarre — drier and more Mediterranean in feel than the green valleys of northern Navarre, with vineyards and wheat fields replacing the beech forests of the Pyrenean foothills. The combination of water sports, open swimming, and a dramatic hillside backdrop makes Embalse de Alloz a distinctive destination within the region.
