Looking for Motorcycle trip advice

Hello! Coming to Sri Lanka in September and renting a motorcycle dirt bike. I normally do ADV motorcycle camping trips so looking for some adventure and 'off-road' while not being crazy unsafe. So far -

Galle Fort

Mirissa?

Udawalawe

B35 Road

Liptons Seat

Horton Plains

Devils Staircase

Nuwara Eliya

Knuckles National Park

Minneriya National Park (safari)

Dambulla

Kalpitiya

This are places I want to ride through on the trip. Am I missing anything? Any recommendations?

Mirissa or Tangalle, both?

Devils staircase, yay or nah?
