If you have a long day on the trail, there is a creek here beneath an underpass that you can refill bottles (using a filter of course)!

Aside from its stunning views, Grand Prospect makes a logical turnaround point if you're not planning a point-to-point hike along the entirety of Rattlesnake Mountain.

Stan's Overlook is a great place to pause for a picnic (there is a picnic table), and to enjoy views through the trees of Mount Si and the Snowqualmie Valley.

Very nice and easy path. If you decide to shorten via one of the MTB trails: Not all the bike trails allow hikers, and on the ones that do, bikers always have the right of way.
