Why now: Despite its name, Iceland's average March temperatures are on par with Boston. And Reykjavik heats up with great cultural activities, including Design March (icelanddesign.is) and Icelandic Music Experiments (March 22-25,musiktilraunir.is). Easter, a sweet five-day weekend, is celebrated with decadent Icelandic-chocolate eggs. But to truly experience Iceland, you'll need to venture outside Reykjavik. For an adventure, organize an outing with Oli Schram (highlander.is/tours/), whose family goes back generations here. Schram's tours feature off-the-beaten-track sights and activities, including snow-scootering around the volcanic Eyjafjalla glacier, traversing geothermal fields and cliffs above black sand beaches fronting the winter ocean. All the while, he'll regale you with stories on the history, politics, and local legends of Iceland. About $500 a day for a family of four.
