I need a little info about Monument Valley. We will be up at Coral Pink for the Memorial Day weekend from Thursday before until Wednesday after. We are thinking about a swing over to Monument Valley on our way home to Phoenix and would spend Wednesday-Saturday there. I know most of the park is on reservation lands but is there any riding we can do while we are there? Not a big deal but since we will have the toys along it would be nice to be able to use them. Any information is helpful.
