In general, visitors should experience few problems travelling in the Canary Islands. The biggest threat Gran Canaria may pose is a bad case of sunburn or a nasty hangover! Regardless of the time of year that you choose to visit Gran Canaria, don't be fooled by cool breezes and cloudy days. Make the most of the glorious sunshine but remember to use a high factor sun lotion and apply it regularly. Also, drink plenty of water to keep hydrated.
Gran Canaria is a great place to party and there are lots of resorts where you can do just that. If you are looking for a more relaxed and peaceful holiday then head for tranquil places on the island. More here...
If you hire a car, please remember not to leave anything of value inside, even if it is locked away in the boot. Use the safe in your hotel to secure passports, money and valuables; don’t leave camera equipment or bags unattended and just like you wouldn’t back home, avoid strange areas or anywhere that doesn’t feel ‘right’. In the event that something happens, file a report at the nearest police station and keep a copy for your insurance company. If your passport is lost, contact your consulate to get a replacement issued.
A backpack which zips up is a pretty safe way to carry your belongings but a concealed money belt or shoulder wallet will certainly keep your money and documents well hidden.
