10 great places to leave the beauty unspoiled

— -- Resolved: Pick a place to visit this year that does not involve trashing the planet. Call it "geotourism," which is defined by the National Geographic Society as "tourism that sustains or enhances the geographical character of a place. It's a destination where you can have an authentic travel experience without harming the place." Jonathan Tourtellot, director of the society's Center for Sustainable Destinations, shares his list of favorites with Tim Smight for USA TODAY.

Grenada"Grenada is one of the last Caribbean island countries not yet overwhelmed with huge, all-inclusive resorts," Tourtellot says. "The beaches are beautiful, the forested and mountainous interior is ecologically rich, and the capital of St. George is the most attractive historic port town in the Caribbean." grenadagrenadines.com

GuanajuatoMexico Founded in 1554, Guanajuato is about 230 miles northwest of Mexico City in the country's historic silver-mining region. "This hilly, Spanish-colonial city teems with life and history," Tourtellot says. "That presents a nice balance for both tourists and residents. Several of the city's historic buildings have been tastefully converted into hotels and restaurants, and the narrow streets of the city center are delightful to wander through." guanajuatocapital.com

Ashland, Ore.Nestled in the foothills of the Cascades about 285 miles south of Portland, Ashland is famous for its annual Shakespeare Festival. It is also one of the USA's most historic and appealing small towns, Tourtellot says. "Ashland's downtown area and surrounding neighborhoods are remarkably well-preserved, with charming, turn-of-the-century Queen Anne architecture. The wonderful array of boutique-type shops and restaurants attracts both tourists and locals." 541-482-3486; ashlandchamber.com

Isle of SkyeScotland If you adore Scotland, you'll love this quiet island retreat off the country's northwest coast, Tourtellot says. "Skye combines dramatic mountain and coastal scenery with a vibrant cultural and social scene. The residents maintain a strong focus on protecting the natural environment and preserving traditional Gaelic culture. There are castles to visit, tiny villages to wander through, and a wonderful food and drink festival that has become an annual event." skye.co.uk
