The tunnel theme continues up Diamondhead. While the majority of the trail is out in the open, there are some tunnel sections like the one below.
After the tunnels, there are stairs. The fun part was watching the many Asian ladies going up the crater in high heels and skirts.
Beautiful Hawaiian flower...
Below you can observe the crater - it's the brown rim going around. The green foliage is the bottom of the crater. If you look on the left side of the photo, you can make out a narrow strip of road with a black dot in the crater wall. That's the car tunnel we walked through. Then we walked the entire base of the crater floor to the trailhead. I don't know if those of you receiving this blog through email can enlarge the photos, but if you view the photos on the blog itself you can click on them and make them larger (enabling you to see the car tunnel).
