Here's an oldie but goodie for urban adventurers. Check out NBC New York's report last year on ice climbing in the Catskills in which Alpine Endeavors leads a crew up a frozen waterfall.
Alpine Endeavors provided the guides for this particular expedition, but they lead other fun treks, too -- rock climbing, alpine climbing, hiking and snowshoeing -- in places close to as close as an hour and a half away from New York City.
There aren't any hard numbers on the number of calories burned during a typical session of ice climbing, but this site claims to calculate how many calories you burn in an hour of rock-climbing, which is probably the closest substitute. A 160-pound 30-year-old man who is six feet tall would burn about 520 calories an hour, according to the site's calculations.
They've got a couple of ice-climbing trips, but they'll be the last ones of the season, so the time is now. Rates for a one-day basic ice-climbing trip when there are three other people in the group (the minimum required) is $140.
