My mom discovered a new-to-me Seattle spot called the Howe Stairway. It is the coolest!
We started at the top and took a mapped route through an underground mountain biking skills park (it's under the I-5 and first ever urban mountain biking skills park-it's insane rad), up and down more stairs, and a look out to Portage Bay, then back up. I loved seeing many people getting their workout on the stairs.
After the stair tour we went to Volunteer Park and went up the water tower, over to the statue with the famous Space Needle shot and reflection pool.
This is a to-do when you go to Seattle.
