Arima Hotel & Spa is a boutique hotel on the edge of San Sebastián, set across from the Miramón forest and part of the Small Luxury Hotels of the World collection. Its spa, Foresta Wellness Spa, is reserved for adults and built around a water circuit paired with an infrared sauna, plus treatments that use natural cosmetics.
Beyond the treatment rooms, the hotel adds a boutique gym, Foresta Fitness, lit by natural light from the surrounding woods, and two dining spots: Misura, a restaurant built around slow-cooked, seasonal, grill-based dishes, and Tilia Deli & Café, a lighter spot for coffee, snacks and weekend brunch.
Day passes are offered for travelers not staying overnight, though the property is classified as adults-only throughout, and it sits firmly in the luxury price tier. Detailed day-spa hours aren't published online; anyone planning a visit should call ahead to confirm scheduling and whether treatments need to be booked in advance.
The address is Paseo de Miramón 162, a short drive from central San Sebastián, making it workable either as a half-day retreat or as part of an overnight stay at the hotel.
