The kids have to be at least nine yrs. old to ride, so the 8yr. old couldn't go unless she will turn 9 before your trip. My three sisters and I did this, and it's a lot of fun, but do it towards the end of your trip. We were so sore we could barely walk the next day!!!! The cost is about $32 or so, and you walk through the woods and come back the same way you went. It's just a guided walking tour,although sometimes the horses want to eat the bushes and you have to pull them really hard to get them back on the trail! Also, one of the people that was in our group had a horse rear up on him, but he handled it well and the CM's are VERY experienced and keep everything well organized and under control. This guy did get a gash on the back of his leg, but they filed a report and everything was fine, just a scratch really from the bushes. I think the girls would love it, it's a great experience!
