Beaches are the main reason to go to Guarujá. But be aware of the Brazilian beach culture: unlike many foreigners might think, there is no topless in the beaches, but girls can wear tiny string bikinis (fio dental), but it doesn't mean they're exhibitionists. For most of them, it's highly offensive to stare. If you don't want a sunburn and you are typically white, get a strong sunblock for yourself.
A good way to move around to not-so-close places. They are not very expensive and drivers are mostly friendly, although small cheats are not uncommon. To avoid it, after getting into a taxi, check if the taximeter has been started . If not, ask the taxi driver to do so.
Buses are a cheap and nice way to get around by day although by night they are more scarce. The fare is paid on cash to a controller or the driver only inside the bus, by passing through a roulette. There are no tickets. Keep an eye out for pickpockets when the bus is crowded. Many people get still wet from the sea into the bus, so have a good look if your seat is dry before you sit. Check bus routes to the beaches on the beach section below. Bus n.81 goes to all the beaches.
Bicycles are by far the best way to move around the town, but unfortunately there are not many places where you can rent one (but plenty where you can buy). It's not allowed to ride on most of the beaches during the day. Better safe than sorry: buy a lock as well.
Not only seafood but many other cuisines can be found in Guarujá. Barbecue restaurants are a nice option after a whole day of walking on the sands (but never before swimming). Italian cuisine is popular in the Sao Paulo State and is well represented in Guarujá. Japanese and Arabian cuisine will add to the vastness of culinary options. Besides restaurants, vendors are everywhere selling coconut, sweetcorn, sandwiches, ice cream, etc. Kiosks are also easily found on the main beaches where you can try the excellent fresh and clean fried fish, crabs and shrimps.
