CALIFORNIA
1. Go wine tasting
You thought the movie Sideways told you all you need to know about Santa Barbara? You thought wrong. There is, for instance, the Sustainable Vine Wine Tour that we're guessing you haven't tried. The six-hour, behind-the-scenes look at organic winemaking might include a visit to Demetria Winery, lunch with the owners of Ampelos Cellars, and a grand finale at Alma Rosa Winery & Vineyards, run by eco-minded wine pioneer Richard Sanford.
Why it's green You learn about water-saving vineyard techniques and biodynamic practices. And the tour vans run on biodiesel, of course.
Details $125, including tastings, lunch, and transportation to and from the Santa Barbara area; reservations required; 805/698-3911. –Matt Kettman
MEXICO
2. Be a beach bum
The villas at Playa Las Tortugas, 70 miles north of Puerto Vallarta, share 5 miles of creamy beach with nothing but a coconut plantation. When beach-bum fatigue sets in, volunteer to rescue turtle eggs on the beach or to place baby turtles on wet sand, and watch as moonlight sparkling off the waves guides them to the sea.
Why it's green Your help — and tourist dollars — protects turtles at their most vulnerable time.
Details Nightly turtle releases Jul–Jan; villas from $149; 877/287-8905. –Laurel Delp
UTAH
3. Go spring skiing
Next time you're planning a ski trip with your ski-hating spouse, consider this: In Salt Lake City, you get sublime skiing plus the fun of a big-city stay. With the Ski Salt Lake Super Pass, you can enjoy all-day access to lifts at the area's top four ski resorts and base yourself right in town, taking advantage of the best hotels, restaurants, nightlife, shopping, and culture.
Why it's green The pass includes shuttle transportation from downtown — no car required.
Details Buy the pass at most hotels. From $52 per day; 800/541-4955. –Amy Wolf
CALIFORNIA
4. Ground yourself at a spa
At Osmosis Day Spa Sanctuary in Sonoma County, bury yourself under a huge mound of fragrant, fermenting mulch made of ground cedar, rice bran, and plant enzymes. The mixture, which heats naturally, sends you into a warm dream state that's oddly exhilarating. To prolong the sensation, follow an attendant up a wooded trail to an outdoor pagoda for a massage.
Why it's green Can it get much more green than a mulch bath? Plus, all paper goods are composted by red worms ("global worming"), which turn waste into garden fertilizer that's used on-site.
Details From $80 for a standard 1½-hour treatment; from $95 for a 75-minute massage; reservations required; 209 Bohemian Hwy., Freestone; 707/823-8231. –A.W.
UTAH
5. Raft a river
Make like an early explorer: Discover southern Utah's Cataract Canyon from the vantage point of a raft. The canyon's red-rock cliffs are every bit as beautiful as the much more crowded Grand Canyon's.
Why it's green River outfitter O.A.R.S. has an extensive carbon-offset policy.
Details All-inclusive six-day trip from $1,506; 800/346-6277. –Susan Crandell
MONTANA
6. Cross-country ski in pure wilderness
Glacier National Park in winter is something every Westerner should see. And the ultimate place to stay when you see it is the historic Izaak Walton Inn in Essex. The inn hunkers down in a snowy valley bordering the park and the Great Bear Wilderness Area; its groomed trails loop through more than 20 miles of forested alpine terrain.
Why it's green You can take the train. Hop Amtrak's Empire Builder from Seattle or Portland and disembark at the inn.
Details Travel light and hit the inn's shop to rent skis. Rooms from $137; rentals from $20; 406/888-5700. Amtrak's Empire Builder: from $168 round-trip; 800/872-7245. –Lynn Donaldson
CALIFORNIA
7. Sleep by the sea
Tight land-use restrictions around Big Sur mean ocean-view accommodations are limited — and pricey. But the sturdy, spacious yurts at Treebones Resort are a great deal. For a fraction of what lodging along this coastline normally costs, you get a skylight for stargazing and a deck for spotting whales migrating north in March and April. Check out Julia Pfeiffer Burns State Park ($8 per vehicle; 11 miles south of Big Sur; 831/667-2315), where the 0.2-mile overlook trail is as close as you can get to the iconic 80-foot waterfall that tumbles to an off-limits white-sand beach — a prime example of preservation at its best.
Why it's green Treebones is off the grid — a propane-fueled turbine powers everything from the reading lamps to the tiny hot tub, and drinking water comes from a well.
Details Of the 16 yurts, numbers 15 and 16 have gas fireplaces and are most private; shared restrooms are by the lodge. Treebones has ocean-view campsites too; number 4 is our favorite. Yurts from $145, campsites $60 for two; 877/424-4787. –Rachel Levin
HAWAII
8. Escape to a very quiet island
To get a taste of wild Hawaii as it once was, take a prop plane or the ferry from Maui's Lahaina to Molokai, land of high cliffs and few people. The island is largely undeveloped, and the locals fight hard to keep it that way. For a true remote-island experience, tour the Halawa Valley with a Hawaiian guide, who'll show you the restored taro ponds. Picture stacked-rock house sites and shrines, streams to hop across, and waterfalls inviting a clean plunge into the ancestral waters of life.
Why it's green You'll be inspired by an ancient culture that lived off the land for generations.
Details The Halawa Valley Cultural Tour ($75, $45 ages 7–11; reservations required; 808/553-5926 or any activity desk on the island) starts at 9:15 a.m. daily and lasts four to five hours. –Paul Wood
OREGON
9. Indulge your inner foodie
Hole up in a cozy cabin at Leaping Lamb Farm in the Coast Range. Make farm-fresh breakfasts in the kitchen, then venture out to fish or hike.
Why it's green It's all about eating locally.
Details The cabin sleeps six. $75 for one, $25 for each extra guest; 877/820-6132. –Lucy Burningham
BRITISH COLUMBIA
10. Get into the wild in style
Every May, the floating luxury retreat that is King Pacific Lodge is towed in and moored off the coast of Princess Royal Island. From this remote oasis, you can adventure on land (bear-watching and hiking) and sea (whale-watching and kayaking), and follow up each day with feasts of fresh-caught salmon and foraged wild mushrooms. Cool fact: The local Gitga'at First Nation works with the lodge to protect the pristine swath of temperate rain forest that the resort calls home.
Why it's green The lodge was the first in Canada to offset the carbon emissions of guest and employee travel. And it's adding hydro- and solar power to cut its carbon footprint in half over the next five years.
Details May–Sep; all-inclusive three-night stay from $4,795 U.S.; 888/592-5464. –Bonnie Tsui
