If you enjoy gardening, or nature photography, or just love visiting beautiful gardens, you will definitely want to put some of these amazing botanical gardens on your itinerary for the Golden State.
California’s botanical gardens are also great places to take your kids to observe and learn, and for adults and kids alike just to enjoy a green break in the midst of a sightseeing trip.
California’s Best Botanical Gardens
Gardens are so therapeutic! When you need a vacation from your vacation, a garden is the perfect place to go. After you stroll among the plants and trees for a bit, you’ll feel relaxed and rejuvenated and ready to go again.
California has so many beautiful botanical gardens that no matter what part of the Golden State you are visiting, you will find a garden (or three!) nearby.
Many gardens require advance reservations (and advance online ticket purchases), so call the garden you plan to visit (or check their website) for current information before you go.
Excited to discover the most beautiful botanical gardens in California? Let’s get started!
San Francisco Botanical Garden
With more than 9,000 plants from around the world and ten themed gardens, the San Francisco Botanical Garden is a must-visit 55-acre oasis in the City by the Bay.
Walk through a shaded coastal redwood grove in the California garden. Elsewhere, admire fuchsias from the Andean Cloud Forest, marvel at the giant spear lilies from Australia, and take in the fragrance of herbs in the Mediterranean garden.
For a special treat, visit between December and March to see the magnificent magnolias in bloom. San Francisco Botanical Garden has the largest collection of magnolia species outside of China, and the mature trees look gorgeous when covered in white or pink blooms.
We visited in early March to see the magnolias and found many trees showing off masses of waxy blooms. Rhododendrons, in white and shades of pink, were in peak bloom as well, and we also caught the tail end of the blooming of the camellias.

The Huntington Botanical Gardens, San Marino
The Huntington features an astounding 15,000 types of plants in 16 themed gardens, spread over 120 acres. The complex, just outside Pasadena, makes for a wonderful day trip from Los Angeles: apart from the gardens, you can also tour the Huntington Library and Art Collection when you visit.
Must-visit gardens at the Huntington include the Desert Garden, which houses one of the largest collections of succulents in the world, the Japanese Garden with its moon bridge and tea house, the Chinese Garden with its lake and architectural elements, and the Rose Garden, which has over 1,200 varieties and looks absolutely stunning in peak bloom.
A smaller garden we loved at the Huntington is the Shakespeare Garden, which contains plants and flowers from Shakespeare’s time, as well as those he referenced in his works! The herb garden nearby also makes for a lovely wander.
You could see most of the gardens in one full day, if you start at opening time. On our first visit to the Huntington, we took two full days to browse the entire complex, including the art and the library.
