And this site is way out there, requiring a plane ride to a grass landing strip in the village of Kwamalasamutu in the far south of the country where there are no roads, and then a boat ride up river, ending with a long hike in.
And here is one pic of the Petroglyphs.

I would have a lot more cave pics from the cave, but I wasn't the assigned photographer on the trip, so just grabbed what I could.
But a reasonable reminder that there are a lot of photo galleries on my website, although most folks will just enjoy a new photo in the morning.
