On the morning of January 15, 2023, my wife and I rent a car at Maui's airport, and drove to Haleakala National Park. After reached to park's visitor center at 9740ft height, we started hiking on the Keonehe'ehe'e (Sliding Sands) Trail. I was amazed and impressed by those great colorful volcano craters. I used a long-focus lens to shot the images. The trip is a real good memory for me.
