Nestled on 200 acres among rolling hills in a secluded valley 40 miles north of San Diego, Cal-a-Vie combines indulgent European spa philosophies with Californian health, fitness and nutrition concepts.

The Treatment: Hydrotherapy, 50 min. $95
Guests slip into a therapeutic bath designed to reduce water retention and improve the firmness and texture of their skin. Underwater jets massage the body, helping to relieve sore tired muscles and reduce the appearance of cellulite. The treatment can be customized with a selection of antioxidant or anti-aging products.

The DIY version: Spa Director Debbie Zie says, "an aromatic bath is one of the best ways to invigorate [yourself] when you're feeling tired and is an essential step in a slimming program." To recreate hydrotherapy at home, she recommends adding a bath concentrate like Yonka Phyto-Bain, $48 (at the spa), to "de-stress" and she suggests lighting a candle like the Yonka Soothing Massage Oil Candle, $59 (at the spa) whose "wax" morphs into an ointment containing shea and mango butters -- just in case you have someone on hand who's willing to play masseur.

Meaning "infused with spirit," Aspira sits on the banks of a lake that's considered sacred by Native Americans. The spa prides itself on being a journey location for the mind, body and spirit.

The Treatment: Cedars Massage, 50 min. $145
This soothing balancing massage incorporates aromatherapy using fresh native cedar, an herb used by Native Americans to purify and protect.

The DIY version: Spa Manager Shannan Roeh says that a cedar's clean, purifying scent can be enjoyed at home in the bath or shower using Aspira's signature cedar sage soap. (Try Plantlife Cedar Sage 100% Pure & Natural Aromatherapy Herbal Soap $4.95.) "Enjoy a hot bath or warm steamy shower and breathe deeply as the clean fresh fragrance of the cedar is released in the space around you," she says. She suggests you also, "add cedar-infused essential oil (like Aura Cacia, Texas Cedarwood, $3), which boasts many health benefits, to the bath water to further enhance your experience."

Miami's only five-star spa boasts a luxurious treatment menu that specializes in traditional Chinese medicinal therapies.

The Treatment: Customized Holistic Facial, $210

Beginning with a facial assessment to determine your skin type, a therapist selects products to create a facial experience tailor-made to your skin's needs.

The DIY version: While it's not the same as having someone do it to you, Spa Director Osa Mallo says that their facial is easy to recreate at home. Here's how:

Step 1: Cleanse your skin using a hydrating cleanser that won't over dry.
Step 2: Tone your skin with a refreshing toner that will finalize the cleansing and prepare your skin for the next stage.
Step 3: Exfoliate (once a week for oily, twice for dry skin) using a gentle exfoliant to assist in removing dead skin cells, revealing a more radiant glow.
Step 4: Remove the exfoliant with a damp hot towel and, depending on your needs, follow by applying either a hydrating or firming mask. Leave it on for about 20 minutes (she recommends enjoying one of the three Mandarin Oriental's 'Oriental Wisdom', $20 spa CDs in the meantime).
Step 5: Remove the mask with a damp warm towel and gently massage in a great hydrating moisturizer using an upward motion.
Step 6: Find a good eye cream and, for best results, apply it in a circular motion using your ring finger. The spa recommends Beauty by Clinica Ivo Pitanguy PreVious Eye Contour Lifting Gel, $170 (call 305-913-8332), because "it reduces dark circles and puffiness while treating fine lines and wrinkles."

Southern hospitality abounds at this charming spa where several treatments are inspired by the island's coastline and lush greenery.

The Treatment: The Signature Massage, 60/90 min. $175/245

A unique massage experience using heated grain and herb-filled wraps that are placed on key tension areas and major muscle groups to induce deep relaxation and increase the therapeutic benefits of the therapist's massage strokes. Results include relief of muscle tension, increased circulation and a relaxed, nurtured feeling.

The DIY version: The spa director jokes that although guests can't "pack the massage therapists as part of this at-home treatment, they can easily fit any of our Relax & Dream DreamTime Warm Embrace Body Wraps, $38 (call 843-768-6340), into their luggage." She recommends heating the wrap (in the microwave) and applying it to "key tension areas and major muscle groups to induce deep relaxation."
