We are going to YNP in August with 4 kids,4,8,9,&16. We have 14 days for this trip. We are driving from Ohio so about 4 days will be just driving to and fro, so 10 days to spend sightseeing. We are planning to stay on north fork highway between Cody and YNP. My main concern is keeping the kids occupied! What is there for them to do besides sightseeing? Should we spend 10 days exploring YNP or spend a few days exploring something else? This is our first trip to the area so any and all advice is appreciated! Thank you!
