You’ll begin your Bellevue Zip line tour in the parking lot at 14509 SE Newport Way in Bellevue. Their trailer/office is located on the edge of the lot and this is where you’ll sign in. It’s also where you’ll pay $4 for a pair of gloves (if you didn’t bring your own), and weigh in.
Yes! You can bring your camera/phone/selfie stick, etc. The only caveat is you’ll have to accept the risk that it could be lost or broken if you drop it. It’s not hard to hold your phone when you’re ziplining, but be sure to turn the volume so you can call it if you do drop it.
