There was a reason for renting the Jeep Wrangler. It's an uncomfortable tin can of a vehicle, but it beats all shit off road.
We started off early and went to Pu'uhonaunau National Historical Park, the Place of Refuge. Not only is it an interesting historical site, but IMHO it has the best snorkeling on the island.
E apparently likes to take pictures of flowers. Here is an artistic flower picture he took at the park.
We also went snorkeling, of course, and had a great time. The reef there is deeper and hard to access (you got to just from a ledge into the waves), but it was worth it.
Next we went to the beach. Possibly the remotest beach on the island. To get there, you have to drive over a lava field for several miles until the "road" becomes too rough even for the Jeep, and then hoof it the last 1/3 mile. This is where we left the Jeep at the end of the road. I think the 4 or 5 mile drive took an hour each way.Then we climbed to the top of a hill and saw this:
It might be the prettiest beach I've ever seen. And almost no one goes there. That might be why it's so pretty. In fact, it's so remote and unused that green sea turtles nest there. And do you see what else is interesting about it? Look at the sand near the bottom of the picture. It looks green. That's because it is green. There is a large olivine deposit there that is eroding into sand. Awesome!
After spending some time gawking, we drove back on that some road. And Dude, people stay along that road in Tee Pees.
Lastly, we went to the southernmost point in the United States. It's windy there. That night we stayed near Volcano National Park.
