We all know that volcanoes make Islands, but to be reminded by actually walking on the dormant volcano is invigorating.
I always recommend a National Park, and we went to Haleakalā National Park. In this park, they have endangered species that exist nowhere else.
It is ideal for watching the sunrise on the mountain but making sure you get tickets. They are released two months before the date you want to visit, and you might get a second chance two days before you go (not guaranteed).
I did not know that, so we missed the sunrise, but the landscape like nothing I have ever seen. When you are at the summit (10,000 feet up), you are above the clouds looking down on the volcano's crater. Tiny Dunes fill the crater, from a combination of small eruptions (between 1400-1600) and erosion.
When I go back to the mountain, one thing I want to do is do a stargazing tour. I heard the views of the Milky Way are AMAZING! - 3 minutes ago
