The Almaden Quicksilver County Park is one of San Jose’s natural gems. The biodiversity is accompanied by a rich history of over 135 years and 4,152 acres. Wildflower displays, over 34.3 miles of hiking trails, 10 miles of biking trails and 23 miles of equestrian trails make Almaden Quicksilver the perfect getaway. The park is also pet-friendly and open to dog walking, as long as dogs are leashed. Ranger guided tours and walks are available.

Built on the land occupied earlier by the Corpus Christi hospital, one of the city's medieval hospitals. In 1558 the city exchanged plots with Archishop Esteban Almeyda and the hospital was relocated to the Parish of Santiago. The building may have started in the 16th Century, soon after the establishment of the Orihuela Bishopric. It underwent profound changes in the 18th Century under the reigns of Bishops José Flores Ososrio and Pedro Albornoa Tapia. In the mid-20th century, it lost its original functions, was restored at the beginning of the 21st Century and is currently home to the Diocese Museum of Sacred Art. At the back, facing the river, there is a gallery with semi-circular arches. Inside, another striking feature is the cloister with heraldic decoration, the main staircase of Alicante marble and the dome built on an octagonal base, with exterior cobalt blue glazed tiles.

Not your typical zoo, Happy Hollow is rife with rides, play areas, and a Puppet Theater. It also operates as an accredited zoo, with over 140 animals in its conservation-centered park.
