Rifle Falls is a very small, year-round campground (13 electric sites and 7 walk-in tent sites) but it is very popular for day use. In fact, we waited until after 6 pm on the day we arrived to walk the 1.5-mile path to see the waterfalls and caves because it was so crowded on a Sunday afternoon that it required a ranger to direct traffic. We took an additional walk there on Monday morning and it was quiet until around 11 am, when the crowds started to pick up again. 

There are two vault toilets and they were not very clean, likely due to so many non-campers using them. Seven of the RV electric sites are back-in (1-3 and 10-13) and the remainder are pull-through. Not a lot of physical separation between the sites but the sites are large enough and spaced far enough apart. The tent sites are spaced a very decent amount apart with lots of trees between them and carts are provided to bring your stuff to your site. 

In addition to your camping fees, an annual or day-use pass is required to enter the park (applies to all Colorado state parks). 

The main draws to this park are the waterfalls and caves and both were definitely worth a stay in this park to see them.
