It is a challenging run to get up to Sunol Peak, but it is worth it for the wonderful views of Mount Hamilton and Mission Peak.

The panoramic views from Sunol Peak make the strenuous hike to the top worthwhile. Sunol Peak offers stunning views of the Diablo Range, Mount Hamilton, Mission Peak, and on clear days, even downtown San Francisco and the Pacific Ocean. Keep in mind it can get quite windy up here, even in the summer a windbreaker is advised. Bring plenty of sunscreen as most of the trail is quite exposed.

This 2-acre farmstead was once home to Ukrainian expatriate and writer Father Agapius Honcharenko, who lived here in exile with his wife Albina for over 40 years. Born in Kiev in 1832, Honcharenko's writings advocating for peasants led to his reputation as a revolutionary and exile. Facing arrest and death threats from Czarist police, he escaped to America, finally settling in the remote Hayward hills in 1873, where he quietly farmed while remaining a champion of the underclass. Honcharenko died in 1916, a year after his wife. Their home may be gone, but their graves remain under an oak tree. Nearby is his cave "sanctuary". This spot's historical and humanitarian significance as the home of these Ukrainian freedom fighters makes it quite remarkable.
