I found a few appropriate photos for this challenge amongst my holiday photos.
Flight of stairs in ANZAC Square , Brisbane
Climbing Walls are not a way I would choose to get up and down, you climb up and abseil down.
Observation wheels which are really just super sized Ferris Wheels take you up above and back down again, in a roundabout sort of way. The North Star, an observation capsule onboard Ovation of the Seas does the same thing.
The Brisbane Wheel at Southbank was just a dress rehearsal for the Singapore Flyer.
As we often docked at freight terminals we also saw a lot of cranes especially at Port Klang, Malaysia
