We are going to be in Maui April 6-12 on our honeymoon. Both first-timers. We are staying in Kaanapali. I've read many TA reviews and have decided we are definitely going to do the Road to Hana. I also want to see the Haleakala National Park and the blow hole. Question though... is the blow hole INSIDE the National Park, or how do you get there? Should we do the RTH, turn around and come back to do the National Park? Make them two seperate trips? I've looked at the map and read that you really shouldn't travel south of Hana in a rental car. What should we do?
