There are many steps up to the four temple levels. They are steep and uneven from use and weathering. In some places, sandbags were used to fill in gaps but those are falling apart now also. It is even harder coming down. Everything is relative though. The kids there run up and down the stairs like mountain goats.
The picture shows part of the 162 steps up to the Level 1 Temple. The top is guarded by two nagas.
These red stakes at the Level 1 Temple warn visitors that there are landmines on the other side. Just stay on the temple side and you will be fine.
