I was with a couple of colleagues in downtown Seattle between meetings. We were walking along the street just killing some time when we came upon Waterfall Park. Tucked on the corner of a block in amongst the buildings, it is a little area with a waterfall (what a shock I hear you cry) running down an artificial rock face into a pool. It seems set up to provide a restful spot for workers to enjoy in the middle of the day. Indeed, it closes by mid-afternoon. There was a security guy on duty so maybe someone has tried to mess with it in the past which is rather disappointing. I only had my phone with me but hopefully you can get a feel for the spot.
