I love looking at historical artifacts like this, so it was a must do on our list.  There is a short but rocky walk to the site of the petroglyphs, so closed toed shoes that support your ankles might be a good idea.  The ground (lava rock) can be very uneven, so the walk may take a little more time than expected.  Upon reaching the site, you will find a wide variety of petroglyphs, with some of them being difficult to see because they have been eroded over the years.  It was still worth the short hike to see them. If you appreciate this type of thing!  Also, prepare yourself for wind, sun, and rain as we experienced all of the above on our trip!
