Ok guys, please set this confused traveler on the right path.
If staying in Kanaapali and driving up to Haleakala for the sunrise, you take hwy 37-377-378 to the summit ...which is different from the Road to Hana which is hwy 360. (we incorrectly assumed the Hana hwy led to the summit). SO, if planning to see both ...it needs to be on different days, right? Maybe we need to extend our vacation to get all of this in!! Ha, ha! Well, it was a good try!
