Snowboarding is no longer just a guy or teen sport. Everyone is getting involved, but don't be intimidated by those 6-year-olds whisking down the mountain beside you — it takes a little time to get the hang of it. Like skiing, it can be an investment, but you can also rent all your gear until you decide it's worth it. What's more? An 150-lb. person can burn upwards of 340 calories snowboarding.
