The outdoor arena was a rather large structure, built into the hill's side, and closer to the peak it was a sizable distance that required them to utilize an elevator built into the hill also, due to the steep slope. This was for weaker individuals. They doubted the triplets had needed it, they would have just run.
The elevator brought them to a stone bridge attached to the hill that led straight to the arena in the distance.
It was large and designed with similarities to a stadium, except much smaller. No one guarded the entrance as there was no need. So they could walk past it to traverse a short well-lit passage before arriving inside the structure.
From the outside classical music could already be heard, and some who knew what was being played mentioned how they appreciated the academy's taste.
