I visited Arches National Park in Utah in February this year on Presidents day. We drove right into the park off of the main highway. My friend who was driving commented that he never drove into the park entrance without being slowed significantly by a line of cars ahead of him. I am wondering what types of crowds to expect and how it it will impact us both driving around and hiking. We will have this experience (delayed by more cars than usual) when driving to Joshua Tree the second weekend in May (Mother's weekend)? Planning to stay in Twentynine Palms. Time frames for doing things, getting places would be helpful. .Thanks in advance for input, suggestions, recommendations.
