Is it normal for BP's to climb the top of their enclosure at night?

I think the humidity and temperatures are fine
(55-70℅ humidity, 88°F on the warm end, and 78°F on the cool end)

She has 6 hides and lots of clutter, she explores her entire tank but she'll climb up to the rim of the enclosure at night. (Her enclosure lid is mesh and opens from the top)

Shes a young ball python around 2 feet long in a 47 gallon enclosure, so it's surely enough space.

Is this normal behavior? Is she just exploring? Or am I doing something wrong with her husbandry.
