From the 80’s or 90’s it was about a cartoon boy that goes camping and rock climbing in the mountains (none of the landscape is animated). He had blonde hair and I think was wearing a red shirt.
There is a scene by the tent with a bear. And something scary/tense happens while rock climbing.
I can’t remember if there were live actors, but there may have been some kids with him.
The wilderness looked like a National Park.
English movie based in the United States.
