We’re trying to extrapolate to when our kids will old enough to hike the Grand Canyon. Hiking the canyon was one of my favorite pre-kids trips ever, but we did it in late December (which I recommend!) but that’s not a kid-friendly time of year.
If you’ve done big elevation hikes with kids, like the Grand Canyon, what ages were your kids and how did they fare? I liked the linked travelogue which closely matches the itinerary I would probably choose.
