Tight, rocky, and exposed—this one’s a classic if you like your rides technical. The climb is tough, but the views are worth it. Watch for hikers, take the switchbacks, and ride early if you want to avoid the crowds. Not for beginners, but a fun challenge if you're up for it.

A series of disasters has eroded the properties in this area. In 1900, a kitchen fire destroyed the main house, and in 1905, another fire consumed the remaining structures. From 1909 to 1938, a combination of flooding, wind storms, and additional fires destroyed the rest. Here, you can now observe the ruins of the observatory and enjoy the beautiful view from this point.
