I just booked at Watchman Campground in Zion (tent camping) for the weekend after Labor Day, 2014. I will be traveling with my 20month old, husband, and my friend's family (3 kids age 2-7). We will be coming from the Portland, OR area probably down I-84, I-15. I think we need to drive it in two days with a one night stop along the way since it is about a 16hr drive. Does anyone know good places that I might have luck finding a reservation? I thought Yuba State Park might work, but we are looking for Sept 3, and they are booked. It would be awesome if there was water around for the kiddos since it will likely be hot for them. We don't need anything too fancy since we are tent camping. Now I am not sure where to stop and thought I would check here for some good ideas. Thanks in advance!
