K.,
There is a Mission tour. Apparently, there were SEVERAL missions established within driving distance of each other in that area. We took a group of 4th graders to tour them and they were FANTASTIC.
As we walked into one of the missions, I think Mission San Jose... there was a calming peace that fell over us. Being the only teacher on the trip I got the "Rowdy Bunch". Even my group of boys commented on how still it was and how quiet. THey all were strangely more docile while we were there. The chapels are beautiful. The history is interesting...
You might check the tourist center. I remember there was a phamplet that told about each mission, it's history, and special characteristics.
Oh, and I don't think there was a charge to get in to any of the missions. Though it could have been a part of our tour fee. That's a question ot ask at the tourist center.
