As kid we were camping at the Castlerigg campsite and walked to Casterigg from the campsite. I don't think it had much of an impact on my parents but I never forgot it.
Given the accessibility of the site I'm surprised more people haven't listed this as their first experience
I still love it, and visit at least once a year while we are in the lakes.
We got engaged there - no matter how many other places I visit this one will always be special to me
