Sooth aches and pains in a steam caveReenergize with an ancient Thai healing massageNibble on healthy vegetarian dishesRetreat from the beach crowds to Tamarind Springs, an eco-friendly day spa tucked deep within a tropical forest. Ease into a day of pampering by exploring the herbal steam caves (said to soothe achy muscles and get the blood flowing) carved into massive natural rock walls. Then, cool off with a dip in one of the secluded rock-bottom plunge pools. Whether lounging inside of a cave or beside a pool, lather up with the house-made skin scrubs and body polishes set around in colorful bowls. Still clinging to residual stress? Go in for a traditional Thai yoga massage, hot and cold stone treatment, or an herbal wrap in the breezy massage pavilion. If your idea of relaxation is more active, call ahead to book a 90-minute private or group yoga session with one of the spa’s seasoned instructors. Even dining is a tranquil affair. Follow a stone pathway hemmed in palm fronds to 9 Seasons Restaurant, a thatched roof tearoom with a vegetarian-heavy menu. The bulk of the organic fruit and vegetables in the thirst-quenching smoothies, bright spring rolls, and noodle dishes are sourced from small, local farms. If you want to relax within the comfort of the resort the Conrad spa offers a variety of luxury wellness programs and spa treatments using world-class facilities. Tamarind Springs is a 30-minute drive from the hotel. Negotiating a cab fare with a local taxi will only disturb your spa-day bliss, so arrange for the hotel’s car service to take you there and back. ​​TAMARIND SPRINGS: 205/7 Thong Takian, +66-84-459-1563;; open 9 a.m. to 8 p.m.
