Yes, it will take you an entire day and you still won’t see everything—even in winter when some of the park is closed.   In the summer, there are several ranger-guided tours you may take.   They cost $4 per person and may be obtained a day in advance at the park Visitor’s Center near the entrance or the Colorado Welcome Center on Main St. in downtown Cortez.   If you are going with children and don’t have a problem crawling through a short tunnel, Balcony House is the best tour.   You have no other option for viewing Balcony House except for this tour.   We generally do not recommend the Cliff Palace tour because you are never going into the ruin, only in front of it.   You can see Cliff Palace directly just above it off of Cliff Palace Loop or from a distance on the Mesa Top Loop overlook.   You may do the first option in winter if snow doesn’t close the road to Cliff Palace.   The Mesa Top Loop is open in winter.  The above photo is taken of Cliff Palace from the Mesa
