This will vary depending on the region your clients are travelling to, however in general we recommend they bring:
· a first aid kit
· sun protection
· antibacterial wipes or gel
· an international electrical adaptor
· comfortable walking shoes and a pair of evening shoes
· clothing to suit weather conditions (layers are a good idea), including trousers or shorts/skirts that reach below the knee
· a day pack to carry belongings while out and about
· snacks like muesli bars and nuts
· and of course, their passport!
