There is a $10 fee to enter Red Rock Crossing/Crescent Moon Park. There is typically a line of cars to enter, especially in the afternoon, so be prepared to wait at the entrance until a parking spot becomes available.
The path is easy to follow and many people use it as a way to access different areas along Oak Creek. It is paved and wheelchair accessible. There are many short side trails to access Oak Creek. This is very popular with locals and visitors. The surrounding grounds have picnic tables and grills that make for the perfect BBQ lunch opportunity.
You can see Oak Creek through a line of trees between the path and the creek. The best views are of Cathedral Rock, which is probably the most photographed rock formation in Sedona.
