It was hot make sure you have water. You really need to be looking for some of the petroglyphs. The trail now makes a big loop . They don’t have signs at the back of the hike by number 6 letting you know to go right and it will take you back to the parking lot. The park ranger said they had just put the sign up for the loop this week. They are working on additional signage. Still a great experience!
Hot tip: purchase ticket ahead of time. Or, like we did, while sitting on the steps outside. There was a long line and we just purchased our tickets on line and walked right in! I enjoyed seeing the detail and meaning behind the Book of Kells. I wish we could have seen more than just one open page.
