Zen Spa has a variety of treatments in a cute little house, you have to walk over stones in the water, everything is open and the employees are super friendly. A tiny bit more expensive than average but definitely worth the extra dollar or two. It's located in the same alley as Yoga Barn so a good excuse to pay them a visit while you are there.
Yoga Barn offers a range of Ayurvedic treatments customized to your "Dosha" - your specific body type, and is more of a balancing and rejuvenating experience. Great quality products, service and atmosphere. Definitely a more premium offering, treat yo'self! Maybe take a class of Morning Flow first and follow with a Balancing Ayuryoga Massage.
Locally run and tucked away among the rice field in Penestanan Village (conveniently close by to Alchemy where you can get yourself a healthy lunch or juice). We recommend their facial! Plus they also make their own products which we love. (While you are there check out the little health food store next door and of course Alchemy).
KOMMUNE RESPORT AT KERAMAS
Luxury resort right on the beach with a great spa, we recommend a facial and a full body massage. Great environment and atmosphere. Make a day of it and check out their beach club while you are there, also their gift shop offers a mix of local and international brands.
