Bush walking (not really possible with very young kids, but one day I'll get to go again), playing in creeks, games like boules, fun with campfires, spotlighting wildlife at night. Camping is a lot of fun.
Horse riding, swimming, fishing, bushwalking.
Loved camping! Enjoyed the different meal types prepared on campfire or gas stove. Somehow, always tasted better than home cooked meals!
Just the smell of 'the bush' was beautiful. No outside noises. Peaceful. Calm. Brought some 'sanity' back being 'up scrub'.
