In a small corner of San Francisco, there is a beautiful strip of beach called Crissy Fields. From here you can see the Golden Gate Bridge with the mountains of Marin Headlines in the background. It can sometimes get crowded, but if you come at the right time, it's possible to enjoy the beach to yourself. It's a peaceful place to hang out or have a picnic. There are often many dogs that run up and down the beach and into the water, which is great to watch.
Palace of Fine Arts
The Palace of Fine Arts is a museum that's located close to the water near Fort Mason. It has incredible architecture with a huge dome as the centerpiece. The museum is hugged by a small peaceful lake to sit by. Even though it costs money to go inside and see the art, its a beautiful trip to walk around the dome and by the lake. Its also walking distance from Crissy Fields.
Its beautiful in the daytime, but truly mesmerizing in the nighttime. The lights shine on the dome to give it an angelic effect, and sitting under the dome by the water brings a wonderful sense of serenity.
