Love the great outdoors? No wonder! There is an endless variety of activities to enjoy, no matter where you live. Every local offers something different. Get out and taste life!
Gardening
Whether you have acres of land, a small patio, or even just a balcony or window, you can garden. All it takes is a little soil to produce wonderful, healthy food—that actually tastes like food! Gardening is lowcost, and a great way to get outdoors—or bring the outdoors in to you.
Walking
It's easy, convenient, and you can do it anywhere. All you need is a pair of good walking shoes, and you're good to go. Make sure you can take a safe route to avoid common dangers (dogs are a big one, but it depends on your area). No excuses!
Hiking
This is another easily accessible way to get out into nature. Hiking doesn't require any fancy equipment or special skills, just a map and a thirst for adventure. Find out the best options in your area. Trails.com can help you locate trails.
Biking (mountain and road)
Biking is a great way to explore the outdoors, and you can do it in both rural and urban settings. Many towns and cities are getting serious about biking, and you'll find scenic paths that help you see another side of your own neighborhood. Whether you tackle rugged mountain trails or amble along to the farmer's market, biking can offer something for everyone.
What's happening in your neck of the woods? Find outdoor activities for every season, and get out and play!
