@TheLongpigs Oh I’m pleased - thank you! I’m actually a primary teacher, so I do teach some Geography and Science - so half right?!
In terms of ages, I think it depends completely on the child. I’ve heard a rule of thumb that children should be able to walk their age in miles plus one, so a 5 year old should be able to walk 6 miles, for example. When I think about some of the 5 year olds I’ve taught, some would be more than capable of doing this, and some would really struggle. It depends on the child’s size, strength, experience and attitude, basically.
I’ve gone on hikes with 7 year olds happily romping 10 miles or more, but these were kids with loads of walking experience who were used to going on family hikes.
If you have kids you’re hoping to do it with, I would use the age plus one mile rule as a starting point, and then make sure you’ve done practice hikes with them in advance, have got them used to reading a map so they can see how far they’ve gone and what the places look like on a map, maybe get a spotter’s guide type list so they can look out for particular clouds/ plants/ people/ types of dogs even to keep them interested, and get them involved with planning out the snacks! Kids can also carry some of their own gear, and I’ve seen them feel proud of packing and having their own little backpack with water, snacks, rainjacket etc.
I hope that helps! It’s a great trail for children - in part due to the multiple swimming and ice cream opportunities available!
