More awesome outdoor activities

A little while ago, I did this post on some outdoor activities for the summer that will blast calories and provide hours of entertainment at the same time. I just discovered this eDiet's article that lists some other great outdoor activities, namely Whitewater rafting, frisbee, swinging (at the playground, not another type of swinging), gardening and more. I think it's a great list -- they're all things that you can easily work in to your routine, and as I look out at the gloomy spring showers, I can't wait to get out and about. Whitewater rafting is a favourite summer activity of mine -- it's thrilling, refreshing and a really good workout if you're tackling some serious rapids and not just floating down a river.

What other activities can you think of?
