Carlene Sullivan, owner of Symmetree Yoga in North Conway, New Hampshire, has just introduced a 2-night Yoga Adventure, where you take a guided hike or drive to the top of 6,288-foot Mount Washington, and top it off with yoga and meditation on the summit surrounded by the other ridges of the White Mountains. Prices start at $260 per person and include two nights' accommodation, breakfast, lunch, and dinner, yoga class, breath work, and meditation, and transportation to the site from North Conway. Carlene also offers day-trips, where you hike to a serene spot in the Whites and have your own private yoga session next to a waterfall or rambling stream. 
 

How does a rock band offset its carbon emissions from a 32-date world tour in 2009? Well, if that rock band is Pearl Jam, they plant 33 acres of trees around Puget Sound in Washington. The band just donated $210,000 to Cascade Land Conservancy to provide the plantings, which will help to make up for the 5.474 metric tons of carbon used during last year’s tour. The group has been mitigating its carbon output since 2003 and plans to do just that after this summer’s tour. When Pearl Jam rocks out to “Force of Nature,” they mean it.
 

Located near Sacramento, Davis, California, is a city of just over 65,000 people that’s perhaps best known as the first city in the country to create bike lines on their streets. Well, yesterday, they just upped the ante by announcing their intent to cut the community’s carbon emissions by up to 50 percent by 2013. Using the tenets of David Gershon’s book, “Low Carbon Diet: A 30-day Program to Lose 5,000 Pounds,” Davis is creating EcoTeams, peer-support groups to help households reduce their emissions. Cool Portland (Oregon), Gershon’s first pilot program, helped reduce carbon emissions of each household by 22 percent or 6,700 pounds. 50 percent seems ambitious, but kudos to Davis and Gershon for giving it a shot!
 

On the banks of the Mississippi River, Vento Nature Sanctuary is now home to bald eagles, blue herons, and acres of restored wetlands. It’s also popular with rock and ice climbers who like to propel themselves up the steep walls that rise from the river.  Yet, Vento was once a dying rail yard, left to rust by the Burlington National Railroad. Thanks to a grant from the city’s Metropolitan Council and private donations, all contaminated soil was removed and the boundaries of the park were expanded so folks can have more green space to play.
 

One of 34 Boston Harbor Islands that dot the waterfront and are part of a National Historic Park, Spectacle Island had its heyday in the 1840s as a large gambling resort and brothel. As of late, the island was merely a dumping ground for garbage. Then someone had the brilliant idea to create a dike to contain the trash and use the dirt from The Big Dig to reshape the island, providing topsoil for planting trees and other shrubbery.  Today, the heaping mound of soil has created the highest point on the Eastern Seaboard south of Maine. Leaving its smelly past behind, the 105-acre park has a trail system weaving through the interior, beaches to comb for sea glass, and public access by ferry. Local naturalist and Walden author Henry David Thoreau didn’t have Spectacle Island in mind when he spoke of preserving America’s “wild spaces,” but it’s refreshing to see good ole Yankee ingenuity at work.
 

For most of the 20th century, this large plot of land in downtown Los Angeles was used as an immense Union Pacific railroad yard. When Union Pacific closed shop in 1989, the property laid dormant until 2001. As California State Parks hemmed and hawed about how best to convert the space into a park, artist Lauren Bon, backed by a grant from the Annenberg Foundation, had her own ideas. With the help of The Trust for Public Land, they excavated some 5,000 tons of soil contaminated with hydrocarbons and metals, planted more than a million corn seeds, and installed an irrigation system to create her artwork, Not a Cornfield. The large crop has now been harvested to make way for bike trails and fields of wildflowers. Los Angeles State Historic Park is still being landscaped, but close to half of the property is open to the public.
 

The curved rusted steel of Richard Serra’s Wake (2004) resembles the hull of a ship, perfectly suited for Seattle’s seafaring tradition. Children run around the large structure, warned by their parents not to touch. Other families meander by Calder’s tall, red Eagle (1971), eyeing the iconic Space Needle in the background. A dog walker ambles past one of Oldenburg’s signature typewriter erasers, following the zig-zag trail that rises above railroad tracks and leads to the waters of Puget Sound and the snowcapped peaks that stand tall in the horizon. 

Unveiled in January 2007, Seattle’s Olympic Sculpture Park is a glorious addition to the city’s waterfront. It’s even more remarkable when you understand the history behind this 9-acre parcel of land.  For more than 60 years, this section of Belltown was dotted with oil tanks owned by UNOCAL (Union Oil Company of California). The petroleum seeped into the land creating a brownfield that would take over a decade to clean up when operations ceased in 1975. Yet, today, the once vacated industrial wharf is now brimming with life as more than a half-million people visited Olympic Sculpture Park in its first year.
 

The latest trend in urban design is blurring the line between civilization and nature to create parks from contaminated sites, landfills, and abandoned manufacturing plants. This week, I want to focus on green spaces that were once urban eyesores and are now popular spots to walk, bike, and simply be outdoors. For decades, the High Line served as an elevated railway track that brought freight into Manhattan. By 1980, the trains had stopped running and the tracks were sliding into decay that, somewhat remarkable, was also a kind of blossoming. Nature re-established itself as saplings and wind-sown grasses sprouted in the rail beds. The trees took root and so did an inkling of an idea, almost Seuss-like, to create a public space that would be 30-feet high above the city and nearly 1.5 miles long. What a way to see New York, from above!
 

While we’re touching on ecoresorts in Central America this week, one of my favorites is in Belize. Home to the longest barrier reef in the western hemisphere, Belize has long been popular with scuba divers who head to the island of Ambergris Cay to float among the manta rays, turtles, dolphins, and sharks. As of late, however, travelers are heading inland to hike in a rainforest full of parrots and butterflies, visit rarely seen Mayan ruins, and canoe along the Macal River. This is where you’ll find a 365-acre nature preserve in the Cayo district called Chaa Creek. Mick and Lucy Fleming opened this eco-resort in Belize long before green was the magic word. They have grown over the past 28 years decades to include two dozen bungalows with thatched roofs and a restaurant that serves grilled fish from the region. But it’s the grounds, with its brightly colored flowers and a forest of tall mahoganies and cedars on a hill overlooking the river that gives the locale its deep-in-the-jungle allure. The resort’s expertise is setting up rainforest and Mayan tours with guides. Explore the Mountain Pine Ridge on foot or horseback or stay closer to home on the Macal River, where you can swim under waterfalls and very likely spot toucans.
 

When it comes to creating ecoresorts, Costa Rica has always been at the forefront. These boutique retreats in the bush or on the beach employ all the tenets of ecotourism. The lodging is built on land that will be preserved for future generations. They employ and thus give back to the local community financially. They educate both their employees and guests on the natural and cultural significance of the surrounding land. And they use renewable sources of energy and local fare for building materials. But lately, the price of staying at an ecoresort in Costa Rica has come with too hefty a pricetag. Especially when you can get the same scenery from one of its Central American neighbors.

On an archipelago in the northwestern part of the country, a short boat ride from the town of Bocas del Toro, is a three-cabana lodge socked in the middle of the verdant jungle and surrounded by a working cocoa plantation.  All of the cabins at La Loma Jungle Lodge were created from fallen trees and inspired by the architecture of the local Ngobe Indians.  The employees are also local, including your guide through the rainforest and beach to see sloths, armadillos, small crocs called caimans, and the graceful blue morpho butterfly.  At dinner, lobster and conch will not be served, as the owners try to use only sustainably harvested fish like yellow jack. Rates are $110 per person a night, including three meals, the boat ride over from Bocas town, and some of the excursions.
