First Lady Michelle Obama, who rocks sleeveless dresses and skinny jeans, has been imploring us to put down the electronics, get up off our couches, and get active with her nationwide Let's Move! campaign. The program's admirable goal is to reduce childhood obesity (and presumably give our kids a shot at fitting into skinny jeans). As part of the campaign, the National Park Service has named the Boston Harbor Islands an official Let's Move! Outside site.

Visiting the islands anytime is an adventure and entails physical activity. Getting there via ferry rides is half the fun. On August 8, you could hitch a ferry ride to the islands at no cost as part of the Free Fun Friday initiative. Among things to do once you arrive are walking tours of Fort Warren on Georges Island, self-guided hikes to the North Drumlin of Spectacle Island, runs along the jogging paths at Deer Island, and swimming at Lovells Island.

There are some special events and activities, all geared to families, that tie in with the Let's Move! Outside campaign. For example, at noon on Saturdays through August 30, the Boston Harbor Island Alliance will present Go Fly a Kite. The hour-long, free kite making (materials provided while supplies last) and flying activity is held at Spectacle Island, the highest point in the harbor (and, hopefully, one of the windiest).

On Sundays at noon through 2 p.m. through October 12, the Massachusetts Department of Conservation & Recreation will host Civil War Games at Georges Island. I have no idea how to play Graces or Hoops (I'm reasonably sure the latter has nothing to do with modern-day basketball), but guides will be on hand at the free event to lead groups in the vintage games.

See a complete rundown of all the Let's Move! Outside activities at the Boston Harbor Islands. Enjoy a few, and you'll be rocking skinny jeans in no time.
