Ooh you know the Isle of Man! Yes from Laxey to the Snaefell summit would be a good long uphill slog with exposure to uneven terrain. I used South Barrule and the Port St Mary to Port Erin coastal path to train for my first hike to Phantom and I don’t recall any issues struggling with the Grand Canyon terrain. I do remember a later trip carrying my two year old up from Cedar Ridge in June and that was hard, due to the heat plus heavy load, and no doubt a lack of training!
The nose bleeds gets my attention. I don’t think we’ve struggled with nose bleeds when skiing at 7500ft+, but sliding downhill in cold weather isn’t as arduous as climbing in hot weather. I imagine nose bleeds could easily frighten a child.
Given all the advice I’ve had, I really am unsure whether Phantom is a hike for any child who doesn’t live in Arizona. But equally, I’m sure many have successfully completed the hike and have the resulting sense of achievement.
Thank you again for all your advice. It’s very much appreciated.
