I spent one day hiking Angel Island out in San Francisco Bay. There are very few people on the island so it is very tranquil. The hike around the island passes through many historical areas.
First was the Immigration Station, this is where Asian immigrants entered the country. It was often a place used to refuse entry to the US. Immigrants held on the island carved poems into the walls were they were held.
Next was the World War II base where soldiers were prepared for transport to the Pacific basin.
The hike included amazing views in every direction.
Next was a 1960 missile silo.
Next was a Civil War base used to protect the entry into the bay. I saw several deer here.
Finally I was back at the ferry dock. This was once a quarantine center in the 1940s for ships entering the bay.
