Spas are open daily. Whatever treatment you chose at the Four Seasons spa (single treatment US$55-US$380; AE, MC, V; 9am-9pm), you won't be disappointed. After your treatment your gracious therapists leave you to bathe in a frangipani-and-rose-petal-filled tub -- something best shared between two people.
The Ayana resort has two knock-out spas to splurge on (single treatment US$40-US$190, package US$125-US$700; AE, MC, V; 9am-11pm): Ayana Thallaso and Spa on the Rocks. At the Thallaso spa, you bathe in a warmed seawater-fed pool and are pummeled within an inch of your life. This treatment is meant to be invigorating, making it perfect before a night on the tiles. The next day, book into the Spa on the Rocks, which hangs on a cliff top. Pass 2 hours of your time with the "Amazing Jade" massage with warm and cold stones, a 24-point foot reflexology massage, facial, and Swedish deep-tissue massage.

Their package deals present a very good value in this expensive neck of the woods.
Ornate rooms, with chandeliers and dark moody colors, at Henna Spa (single treatment Rp115,000-Rp300,000, package Rp300,000-Rp520,000; AE, MC, V; 8am-9pm) in Villa Balquisse make for an opulent spa experience. The "Javanese Lulur Royal Ritual" is inspired by the prenuptial treatments of the Royal court of Yogyakarta. The 2-hour treatment includes a massage with handmade frangipani massage oil, followed by 45 minutes of the invigorating Lulur skin scrub with turmeric, rice, and jasmine, followed by the yogurt splash treatment. The smells are so overpowering you'll get hungry. Fortunately the spa also has delicious tapas and a wonderful fresh ginger tea.
