Wat Tham Phousi is located on Mount Phousi. It is an unremarkable wat except for the tall cupola topped with a single parasol and surrounded by 4 more parasols at its 4 corners. I did not see anything else like this in Luang Prabang. Additionally, it is built into the side of a large rock.
Many of the pictures I took of this wat are of the steps leading up to Wat Tham Phousi. Colorful murals and Buddhist sculptures make a feast for the eyes. There is a large, smiling, colorfully painted parinirvana plaster sculpture where we met a Laotian couple currently living in Seattle. Small world!
The view from the wat is quite wonderful and worth the trek.
