Mariposa Grove of Giant Sequoias – Yosemite Mariposa County, California

Located in the southern portion of Yosemite, the Mariposa Grove of Giant Sequoias is the largest sequoia grove in Yosemite and is home to over 500 mature giant sequoias. The most famous tree in the grove is the Grizzly Giant, one of the largest trees in the Mariposa Grove and, at an estimated age of 3,000 years, one of the oldest living sequoia. There is a two-mile hiking trail, the Grizzly Giant Loop Trail, that will take visitors to the tree. It is a moderate route that takes hikers past notable trees such as the Bachelor and Three Graces, the 3,000-year-old Grizzly Giant, and California Tunnel Tree. Beyond the Grizzly Giant sit hundreds of lesser-visited sequoias in the upper grove including the Clothespin Tree, the Faithful Couple, and the fallen Wawona Tunnel Tree. Reaching the upper grove is a longer hike with elevation gains, but well worth the exercise. www.yosemite.com

The Gardens at Hearst Castle, San Simeon

Publishing magnate William Randolph Hearst started to build Hearst Castle on his ranchland overlooking San Simeon, SLO CAL in 1919. By 1947, the hilltop complex included a twin-towered main building, three sumptuous guesthouses, and 127 acres of terraced gardens, fountains, and pools. Today visitors can find secret hideaways and stellar views, and a walk through the lavish gardens reveals a myriad of colours and scents with magenta bougainvillea, sweet-smelling hyacinths, and rhododendrons at every turn. There is always something in bloom here—orange California poppies (the state flower), fragrant star jasmine—and plenty of pretty settings to photograph. Docents are often available to answer questions: ask them for some of the insider secrets to this garden, like that shady corner where big-name stars from Hollywood’s Golden Age, frequent guests of Hearst’s, used to steal away for an illicit rendezvous. www.slocal.com

Amir’s Garden in Griffith Park, Los Angeles

Spanning more than 4,300 acres, Griffith Park is one of the largest urban parks in North America and home to some of L.A.’s most popular attractions, including the Los Angeles Zoo and the Greek Theatre. Tucked away on a steep hill in Griffith Park, Amir’s Garden is a labor of love enjoyed by hikers and equestrians alike. The five-acre garden is the legacy of Amir Dialameh, who worked on the shaded grove for 32 years. After a major brush fire scorched the area in 1971 Amir planted pine and jacaranda trees for shade, along with rose bushes, geraniums, oleander, and yucca, transferring the barren hillside into a beautiful oasis. Amir also built stairs to the picnic area and added colourful wooden benches. Today this gift to Los Angeles is maintained by volunteers and volunteer groups, with assistance from the City of L.A.
