Back when I was in my 20s I traveled with my parents and oldest nephew, who was around 12, to the British Isles. We hit England, Wales and (Republic) Ireland. My parents had been before, so I chose a lot of the sites that we visited. Most of the places I suggested were ancient sites, so we visited chamber tombs, long barrows, standing stones, stone circles, etc. Some were so little visited that we followed narrow cow paths… But it was fun.
That trip was the start of a tradition for my parents. They took all of their grandchildren, and later, great-grandchildren, on an overseas trip when they were 10 to 12.
And I had traveled overseas quite a few times in those years, but never to the British Isles.
