Angel Island San Francisco is the largest island in the San Francisco Bay. It is just over a mile from the shores of San Francisco. The only way to and from the island is by taking one of the Angel Island ferry rides or your own boat.
Situated a little to the north and east of Alcatraz, Angel Island is a California State Park. This was not always its role and it is another island in the bay with a lot of history.
Angel Island is an easy day trip from any location in the bay area. Hiking, biking and photography are the three key activities on the island. Along the way, you can also visit some of its historical buildings. It is a great way to spend the day for those looking for a more serene outdoor environment that is still close to the city.
Before we get started on the activities on the island -- let's take a step back a few decades -- and dig into its rich history.
Angel Island San Francisco was a sleepy site used by local Indians for fishing and hunting for thousands of years. In 1863, the federal government needed more land in the San Francisco bay to protect the area. At that time, they took control of Angel Island.
It became a US Army base called Camp Reynolds. The military used it as a base for the remainder of the Civil War and for a few years after.
In 1910, Angel Island San Francisco turned into a detention center for unwanted immigrants arriving to the US through San Francisco. Most of these immigrants were from China. At the time, strict laws were in place to minimize immigrations from China.
Almost all that made the journey from China ended up here first. On the island, they faced tough questioning before entry was granted. Some spent months or even years on the island trying to become US citizens.
In 1940, the main immigration building burned down. All immigration related business moved to a new facility off the island.
The military reclaimed the island during World War II. This is where they detained many prisoners of war, specifically those from Japan and Germany.
After WWII, the military moved off the island and it was vacant for a while. In 1963, the State of California declared it a state park and that is still its purpose today.
No one realized the importance and the history that remained in the buildings. The state scheduled the demolition of the buildings in the 1970s. However, shortly before demolition, a park ranger noticed poems and other writing on the wall and carved into the wood work. The state decided to leave the buildings standing.
Many people and organizations stepped in to determine a way to raise funds to restore the buildings. The park was able to get money from both the state government and through private donations.
Restoration on the buildings started in the mid-1970s and continues to this day. The great news is that a few are already open and welcome visitors.
There are three main buildings that house small Angel Island San Francisco history museums. Here is a little about the three buildings open for visitors:
If it is your first time on Angel Island San Francisco, I recommend starting at the Visitors Center. It contains all the information about activities and places to see on the island. Even if you have your day planned, it is a great way to take a quick look at the layout of the island before you set out.
Most people head over to Angel Island San Francisco for the outdoor activities. This is such a beautiful place to go for some hiking, biking and other outdoor fun.
These are my three favorite things to do on the island. There are over 13 miles of hiking trails and 8 of those miles allow the use of bikes.
One of my favorite hikes is up to the highest peak, Mount Livermore. It is 788 feet high and is about a 2.5 hour round trip hike from the ferry drop off point. The summit is about 2.5 miles from the ferry, making it a 5 mile round trip hike.
From the top, you get some amazing views and pictures of a number of places around the bay. Alcatraz Island is just off to the west of the island, so you get a unique look of it from this angle. You can also get a great shot of San Francisco and the Golden Gate Bridge.
If team sports is your plan, then you will find both a baseball diamond and two volleyball courts on the island.
The baseball field is an old field used by soldiers when Angel Island San Francisco was a military base. The field is open for use on a first come, first served basis.
There are two places to play volleyball on the island. The first is near Ayala Cove. Reservations are required for this court, so call ahead for availability before heading over. The second court is open and is at Ft McDowell. The second court is more of a gamble, since the park does not guarantee availability of these courts.
Angel Island San Francisco allows overnight camping. There are nine camping sites on Angel Island and reservations are required. Contact Reserve America at (800) 444-7275 to reserve a spot.
I have never camped on the island, but can imagine it would be fun! I recommend bringing along some warm clothes as the bay is windy and chilly at night.
There are a few tour options. The easiest is an hour tram ride around the island. It picks up at Ayala Cove and drives along the flat fire road the circles the entire island. Do not confuse this with the shuttle ride over to the Immigration station.
Last time we were there, we also noticed that you can tour Angel Island on a Segway. This tour lasts two hours and takes you to most of the historical sites on Angel Island. This is a unique experience and it looks like a lot of fun.
The tours run a couple of times a day. Call the Angel Island reservations office to book your trip at (415) 897-0715.
Angel Island San Francisco is also a great place for a picnic. They have a number of picnic sites. You can choose from a larger site for a big group picnic or one of the many smaller picnic sites around the island. The larger sites take reservations.
You can also grab a quick bit and a drink, after a long day of hiking or biking, at one of the two restaurants. One is a simple cafe, but is open most of the year. The other is a restaurant, but only open during the busier times of the year.
Visiting Angel Island requires a little more planning, since there are only a few ferries back and forth during the day.

The weather on the island is unpredictable also. It's similar to San Francisco weather.
It is nice and cool one day, warm the next and really windy the following day. You can check out the San Francisco weather forecast for the day to get a feel for the weather on Angel Island.
The hiking trails are pretty easy. You should bring along comfortable shoes, water, snacks and a lunch for your day. You can also stop at the cafe before or after your hike.
The same is true with the biking. The biking trails are mostly easy with a few steep areas. You should bring along food, water and a jacket to stay warm when you stop to take pictures.
If you decide to camp overnight, prepare for a cool and windy night. Very little blocks the wind on Angel Island, so bring along warm clothes.
Most nights are between 45 to 55 degrees. In September and October, it is a little warmer with lows in the upper 50s to lower 60s. It rarely gets below the 40s on the island, so it should be a nice, cool evening.
The Blue and Gold Ferry Fleet Company in San Francisco offers ferries from San Francisco to Angel Island. You can also hop on an Angel Island ferry from Tiburon. There are one to three ferries a day depending on the time of year you are planning on visiting, so check the schedule before planning your visit. Learn more about the Angel Island Ferry including pricing, a schedule and more.
Another way to learn about the island is by taking a bay cruise. This is a great way to learn a little bit more about the island without having to step off the boat. These cruises take an hour trip around the bay. Learn more about taking a bay cruise.
Overall Angel Island San Francisco is a fun trip. It has beautiful views and it's a fun day away from the crowds in San Francisco. I would recommend this for those traveling with children. I also recommend it to those that have visited San Francisco a number of times and are looking for a new adventure.
