Walkable from the Sunriver Resort and near Bench with a Golf and Mountain View. Get two caches for the effort. Definitely doable by bike. Parking would be at the nearby Sunriver Resort.
The cache affords you view of the ponds and if you're lucky you'll see the Beavs. I've seen them twice on my bike rides. However, Beavs are secretive furries and luck will have to be on your side. There is also a Beaver group in Aspen Lake by the Nature Center. Supposedly an hour before or around sunset is the best time to see them.
Out of Bounds should take you to GZ without a GPS even. Enjoy reading about the local flora at the nearby info kiosk.
