Hiking (glacier) 3:34:40 [3] 5.29 mi (40:35 / mi) +442ft 37:36 / mi
Glacier trek on Skaftafellsjokull. We booked this the previous day. It was the only glacier trek that allowed kids under 14 but we still wore harnesses, crampons, and held ice axes. So it was the real deal, just a shorter distance and less intense terrain. Nevertheless, I'm not sure this would have worked well last year. Daughter needed a little extra help in some of the steepest sections, but not a big deal. We were in a small group (10-ish folks) and our guide was also a volcanologist/university professor so we got a bonus tutorial on Iceland's 30 volcanos. He pointed out the main features of the glacier, took us over some "stable" crevasses, discussed current research and encouraged the kids to hack away at the ice w/ axes to their heart's content (son was in heaven and could have spent all day doing that).
Kids debated at length which tour so far was the best (whale, glacier amphibious boat, or glacier trek). No clear conclusions. All front runners!
