Perhaps also voluntary crossing of small rivers, small lakes, flooded areas. If you're lost in a mountain and your choice is to cross a river or do a 20km walkaround, being able to swim makes a big difference (chances are you'd avoid going in the mountains altogether, but that missing a lot of fun) Also adults know how to avoid falling into water, small kids are not so good at this game yet.
