Travel Aware The Seychelles
The UK Foreign Office has a very good website with plenty of useful advice on travelling abroad and it also offers up to date information on the safety & security situation in each country.
It is therefore a good idea to get up to speed with your chosen destination/s by visiting the FCO website before you set off: https://travelaware.campaign.gov.uk/
You may also wish to follow the FCO on Twitter so as to get updates whilst you are abroad @FCOtravel. This service aims to help travellers have a trouble free trip by providing advice and information before, and during, their trip abroad. It will also provide assistance in the case of an emergency.
