Dangers and Nuisances
The Canaries are not really dangerous and the worst that is likely to happen to you is sunburn and/or a hangover!
Violence against tourists is very unusual and common sense at all times should spare you any grief. The most common crime in the Canaries is theft from hire cars.
Advice
Should you leave your car overnight in the street of one of the big resorts or towns, there is every chance that your car will be broken into.
Do not leave anything of value in your car (even locked in the boot) or in your hotel room. Use the safe that is on offer to you by your hotel.
Pickpockets and bag snatchers are also a problem and they have got their act together.
Beware of people that brush up close to you or jostle you and don't leave bags and camera equipment unattended for even a moment.
Avoid dingy, empty city alleys and back streets or anywhere else for that matter that doesn't feel right at night.
If you are the victim of theft, you must report it to the police and get a report copy (Denuncia), if you want to make an insurance claim.
If your Passport is taken or gets lost, you must contact the consulate to get a replacement issued.
Nuisances
There are not many nuisances, but noise in the major resorts can be a problem.
If it does get too noisy... leave and head for the more tranquil areas.
Another nuisance you may encounter are the loud and drunken louts that can become quite unpredictable.
If you are going to Tenerife to 'party', remember that the local lager is several times stronger than your normal brew.
You will no doubt come accross the "looky looky" men selling imitations of designer sunglasses and jewellery, as well as ticket touts, give them a wide birth and your holiday will go smoothly.
