In some bends the roads up in the Troodos range can be dangerous, and even if you drive slowly it can become dangerous sometimes.
There are those tourists who are not used to driving on the left hand side and they can cause accidents.
Also be sure to have the scooter full before driving up the mountains. Work out the distance of the gazoline stations on your return trip.
Drive slowly and make a stop and enjoy the scenery instead of driving and looking around.
Especially on a Sunday (as many many of them are closed)....
Calling this a "warning or danger" may be a little OTT, but if you run out of petrol in the middle of nowhere, then yes, it may be a danger! There aren't many petrol staions in the mountains, so it could be a worry if you are running low.
If you are taking a drive up the mountains, make sure you have enough petrol to get there and back.
This can't be avoided but u can lessen the amount of insect bites if you carry along a can of insect repellent wid you. There are tons of mosquitoes up in the mountains so remember to keep ur room windows shut at all times! There are also snakes which are surprisingly afraid of human beings and only attack for defence.
