Is it allowed to enter the park and use the going-to-sun road with a 23ft motorhome during next year June?

The maximum length is 21 feet, and they are very strict about it. Also, sometimes the going to the sun road is closed until late June or early July.

Not only is it not allowed it’s unsafe and Not nice for others. The road is steep, narrow, and a tight squeeze for cars and trucks. If your in a motor home do everyone a favor and take the red bus tour.

Height limit is 9 feet
