About a mile into Santa Clara county, if you know where to look, you might spot a bald eagle. Hopefully, someone with a really good camera will post a photo and tag the location.

Calfateras road begins by a robust climb, and then it changes to a series of switchbacks with spectacular views to the reservoir and surrounding park. The switchbacks alternate between downhill and moderate climbs, before a long downhill and flat terrain.

Biggest peak in the area. If you go when it's open (weekends as of today), you can do the tour of what was once the largest telescope in the world (still one of the biggest refraction telescopes). The observatory is still active

Riding south on Felter road from Calaveras after doing Polamares and and Calaveras Roads was a real challenge, especially since it was my first time! Get something to fuel up on at the Sunol Little Store!
