When to go
All months of the year are suitable to photograph the spiral staircase.
By visiting in the late-afternoon you will avoid the very harsh light (and heat)!
Field tips
To frame the entirety of the staircase in this Look Down shot you’ll have to really stretch your arm out! Make sure not to drop your camera.
Get creative with your composition! I split my composition 50/50 by using a model’s pointed finger neatly along line of the grass patch and pavement.
Try placing your model on the grass patch at the bottom of the staircase or on the staircase itself.
