San Francisco travel tips
The Victorian buildings of Alamo Park, Painted Ladies, are often seen on postcards with local attractions. They are also called "six sisters". These buildings survived the 1906 earthquake. Some buildings house museums. Inside the walls are red, as they are made of sequoia. You can take part in a walking tour of the park but be prepared to walk a lot.
You can go to the IT specialists' mecca, Silicon Valley, on the CalTrain. The average cost of a trip to Palo Alto is $10 (€8.50). The train runs every 30 minutes on weekdays.
If you love craft beer, then this city is a perfect match for you. San Francisco is bursting with microbreweries experimenting with different flavors and trendsetting beer culture across the states. You may want to have a beer at places like Cellarmaker Brewing Co, Mikkeller, or Church Key.
