We went up to Haleakala on our 4 year anniversary in March 2015.
What an incredible drive up a rather windy road to the top of a volcano! A f’ing volcano which was rather wonderful (I want to say totally awesome but that would be a cliche). One thing that people warned me about was how cold it was up there so I made sure that I brought my down jacket!. It was 27C when we left Lahaina and it went down to 10C on the top of the volcano.
We made the decision not to go see the sunrise on Haleakala since it seemed pretty ridiculous to wake up at 2:30am to get to the top. It was beautiful enough at 1pm and I can only imagine how nice it would have been to be there for sunrise. Next time? 😉
