Mission Peak is a popular peak in Alameda County. The trail to the top is well signed and strenuous but it worth it for the great views at the top. A lot of the trail is exposed, so it's important to have enough water and sunblock.

This monument is to commemorate the synthetic chemical element livermorium. The majority of the research for livermorium was done here in Livermore, California, giving the element its name. The fountain and base weigh 18,000 pounds, but they can be easily rotated by hand because they are floating on water (only 20 psi is used to make this ball moveable).

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.
