We are going camping with a group of 27 people and I am organizing a scavenger hunt. I want it to be challenging and different! Ideas, please!!!
What about doing some photo type items? Everyone seems to have a camera cellphone on them these days!!
Here is a site with some good ideas:

i agree with the photo hunt....
A few years ago we had one for our church. Our pastor put it together for our group. We were broke into teams and each team had a digital camera and a list of items to photograph once found....we had to drive all over town (which you could alter) and which ever team finished first won....
Some of the items we had to photograph....
*two members of your team washing a strangers windshield
*someone from your team with a cop
*someone from your team flipping a burger at mcdonalds
*a girl from your team holding up roadkill (yep that was me)
*a picture of Pastor taken tonight (man we had a hard time getting that one)
Good luck...sounds like fun!!!!!!!!
Oh man that sounds like so much fun!! I want to go!! I have my own tent and sleeping bag!!
IF you know the area.. have them take pics of pinecones.. squirrel.. cardinal.. etc.. if your are mean. you might throw in a pic or two of poison ivy...and whoever wins.. get the calamine lotion as the grand prize !! 
umm rachie.. what was your roadkill?
Great ideas! I especially like the photo of the poison ivy....I'll give bonus points for that one! I'm going to get paint sample cards from Home Depot and whoever gets matching colors will make up the teams. We're also going to play games from "Minute To Win It" show.
Photo hunts work great, especially for camping where people would otherwise be picking up things that really ought to be left in their native habitat, you know? Also, with photos you are not limited to physically small objects. 
Some things that you might hunt for in a campground, other than appropriate local flora and fauna:
Largest collection of bicycles parked in a single campsite
Tent that is NOT brown, green or blue
Group inside an RV or tent trailer that does not belong to any member of the group
S'mores
Group member(s) with a park ranger
Totally-inappropriate-for-camping appliance or other device/household item (e.g., television, curling iron, umbrella stroller, nail polish)
We had a whole list of family friendly items, mostly take your picture with... and then we moved and didn't get to do it.
A few from the list:
Picture of an adult on a kid playground slide
Picture of everyone in the family in a fast food restaurant play zone
chopsticks or soy sauce from a local chinese food restaurant.
Picture of at least 2 people with a statue
Picture of someone IN a water feature of some kind
Leaves from at least 3 kinds of trees
Grass clippings
A deposit slip or envelope from a bank.
