Travel Tips for San Francisco

1. Don't try to predict the weather. Bring a warm jacket and sweater so that you're prepared for changes in the temperature; even in the summer months of July and August, it gets cold.

2. Buy a prepaid phone card. Many of the phone booths at San Francisco airport and in the center of the city only accept prepaid calling cards.

3. Pre-arrange your hotel stay—especially in the summer months. Don't assume that it will be easy to find a room when you arrive. Hotels fill up quickly in San Francisco, particularly in the summer.

4. San Francisco is a great city for walking—but there are hills! Bring a comfortable pair of walking shoes if you're planning to go around on foot. Also, you can prevent stiff muscles by stretching, or avoiding the hills on the first day.

5. There are many wonderful cultural events happening in San Francisco all year round. Go online to get a preview of events happening at the time of your visit.

Safe Travel

Many travelers feel nervous about going to a new and unfamiliar place. If you plan your trip carefully and learn to take precautions, you can relax and enjoy yourself.

Check Your Paperwork¹

While you prepare for your departure, make sure your paperwork is organized. You'll want to check the dates on your visas and passport. Having an important document expire before or during your trip is the last thing you want to happen. Be sure to get an international driver's license if you plan to drive while you are abroad. Also, do some research on the local currency. Some countries like Jamaica and —use more than one currency. It's best to know how and when to use each.

Mind Your Health
If you need to take medication along, keep it in its original container. If you are carrying prescription² drugs, bring a letter from your doctor in case customs officials question you at your destination. Also, make sure that you travel with proper medical insurance so that if you are sick or injured while traveling, you will be able to get treatment.

Pay Attention
As a tourist, you'll probably stand out on the street. Unlike local people, you'll carry guide books, refer to maps, take photos, and look up at buildings. Because of this, you may appear vulnerable. Stay safe by keeping one eye on the amazing sights and the other on your personal items.

When you get into a taxi, make sure there is a meter³ and that it is turned on. If there is no meter, agree on a price before starting out. Your guides recommend protecting your luggage in busy transportation areas by always keeping it in front of you or between your legs. Also, if you are going anywhere that requires purchasing tickets, be sure to buy them at an authorized location. Never purchase tickets on the street, as these are often overpriced, fake, or expired.

Learn About the Locals
It's always a good idea to buy a guidebook and a map, and read about the local culture of the country you will be visiting. For example, it's important to know that in India you should use the right hand to eat, or to give and accept things. In Thailand, it's rude to point with your feet at someone or something. Also, try to learn a few basic words and phrases of the local language. Don't assume that everyone will speak your language or that they will understand English.

If you have trouble communicating, look for students and young people who might speak a foreign language. And remember to smile. It's the friendliest and most sincere form of communication, and is understood everywhere in the world!
