What to bring with?
Luggage with wheels is always a good idea, wherever you are travelling. Some ideas:
Light coloured clothing that doesnt absorb the sun as much as dark clothing.
Long-sleeved shirts and trousers will help protect you against the sun and possible insect bites.
A cap/hat that covers your head and neck.
Sunglasses.
Comfortable sandals and tackies/trainers/sneakers. Sun screen (at LEAST Factor 35 I would say), headache tablets, and usual little things like some plasters for blisters, cotton wool, germolene etc. Your camera, with charger, and an appropriate plug extension/adaptor. Have a map of the area handy, plus a local bird, flower and tree book. For this you also need a pair of good quality binoculars.
