Located in the stunning Sintra-Cascais Natural Park, the Onyria Quinta da Marinha Hotel provides a healthful green outlook with a backdrop of the Atlantic Ocean and the Sintra Mountains. It also provides space for the 18-hole, par 71 golf course covering 5.870 meters that was designed by Robert Trent Jones. Besides this, lies a large curved pool and loungers – a further pool is found indoors, in the spa area. The five-star property was refurbished in 2020, taking its decorative inspiration from the surrounding nature. Its Five Pines Restaurant serves gourmet cuisine, with live music on offer in the Trent Jones bar.
