San Diego, Balboa Park, Botanical Garden
The Botanical garden in Balboa Park is another of the must-see attractions.
In order not to lose any of the park's museums, it is advisable to bring a map. You can easily move around on foot, but if you want, you can also get on the free Park's Tram.
If you plan to visit more than one museum, you can buy a combined ticket, which gives access to all of them.
