Camping related party favours?

My daughters birthdays are coming up. They will be 6 and 4, we are having a party with guests will range from 4-8yo.
I am looking for some ideas for camping/orienteering/outdoor related party favours. Trying to think outside the box a bit. I was thinking about a compass (some kind of chinese import). But other ideas would be appreciated.
Our parties are low key affairs.. no decorations, food is close to what you get at bunnings on a saturday morning, location is Blue Gum Hills National Park (which has a picnic and BBQ area that a kids play area... made of cubbies and tunnels and a timber maze, rather than modern plastic playground stuff.
Last year we ran three activities... 1) the kids 'fossicked' for gems that I had bought cheaply from our local rock and mineral club. 2) they glue googly eyes and the gems onto rocks 3) they had a scavenger hunt (finding animal poo was the highlight).
The kids took home the rock thing that they made, the gems that they fossicked, and one lolly. Simple, not over the top.
This year, we are doing 3 activities again. Probably as follows 1) a string orienteering course (basically kids hold onto the string and walk about 100m past 8 control points, they love it), 2) a larger orienteering course (Blue Gum Hills has a permanent course), this will be a adult/kid thing 3)The scavenger hunt again.. because they loved it last year.
