There's no more appropriate way to tour the landscape of sustainable living than astride a two-wheeled – and zero-emission – steed. That's why Portland Peace and Justice Center organized the Sustainable Energy In Motion Bike Tour [1], which organizes summer bike trips throughout the Pacific Northwest to visit organic [1] farms, natural wonders, Native American communities and sustainable businesses, while camping under the stars, doing service projects and learning about green building and clean energy.

The trips [2] range from one to three weeks long and are open to both novice and advanced cyclists. You can follow Oregon's legendary Route 101 [3] along the coastal bluffs, or cruise the Columbia River Gorge [4] learning about permaculture and sustainable business. “Change your world, one mile at a time,” goes the motto.

If you want to splurge and take a deluxe bike tour throughout Europe, New Zealand or Vietnam, check out VBT.com [5], an international cycling outfit headquartered in Vermont. It boasts “time-tested itineraries, a variety of cycling routes, full van support, expert trip leaders, outstanding hotels, and regional cuisine.”
