After cleaning up the trails, it's time to get out and enjoy them. Use the Sierra Club's new user-generated online resource, Sierra Club Trails, to find need-to-know information about popular trails around the country. The Sierra Club is also offering series of backpacking adventures and volunteer vacations this spring and summer. Experiences include group hikes in your local state park, women-only beginner backpacking through Colorado's Rocky Mountains and a multigenerational hike through Tahoe National Forest in California.

In early April, the Sierra Club will also launch a site where people can make a pledge to participate in a specific action for Earth Day. That can be as easy as planting a tree, bringing a reusable bag to the supermarket or planting an organic garden. Participants will be entered to win a trip for two to Hawaii's Volcano National Park.

Even specific hotels and resorts are getting in on the Earth Day action. Located on Washington State's Olympic Peninsula, Lake Quinault Lodge and Kalaloch Lodge are offering volunteer opportunities to all guests. On Saturday, April 17, volunteers can help clean up the Kalaloch beaches with the Washington Clean Coast Alliance. And on April 24, guests can work side by side with the Park Service to help restore the Kestner Homestead Trail. Participating guests also receive special pricing on accommodations.

The Grand Velas Resort Riviera Nayarit recently launched a series of green activities in its kids' club in honor of Earth Day. Resort guests ages 4 to 12 can work with a marine biologist to release baby turtles into the sea, work on the property's garden, prepare a meal with organic items and create art projects out of recycled materials.

Kimpton Hotels and Resorts, a leader in brand-wide green initiatives, has ongoing incentives for guests who drive hybrid vehicles. For example, Hotel Allegro in Chicago offers free parking to hybrid drivers, while Hotel Vintage Plaza and Hotel Monaco in Portland slash their nightly parking rates in half.
