There are many petroglyphs on and around Saint Vincent. Are all accessible? Unsure, and I only visited one of them not on the list. Reason why it's not on the list is unknown, reason for me to go there is because it was advertised, it was a high chance to be open and it has a museum. There is one petroglyph right in Kingstown but I didn't try to visit but for those not willing to take a ride up to Layou then think if it as a possible alternative. Anyway I was on my way up to the volcano and the bus dropped me right off at the road towards the museum. As the website says there is a sign and 0.4 miles later you end up at the park office. Entrance fee is $2 or EC$5 which is the better deal. A lady gave me a quick introduction totally different to what I read online. The "museum" is just a bunch of photo collections from what must be their best bunch. I actually expected to see these but after a lady takes me to 7m wide rock the tour is already done. Now I could use more time relaxing at the picnic area as the river has a cool aura effect but she leads me back outside and locks the door. 5 minutes well spent. I suppose I'm happy I can tick this off and head on.

Apparently the face represents a god called Yocahu. I read this online, no info from the visit was really useful. The art is from 300-600AD. Little info is known about this. The people who used to live here are long gone.

So should it get inscribed? Hmm... I've seen worse art inscribed and it use unique, but very tough to say.
