When packing for your trip, it's important to not forget your toiletries. Even when visiting the bigger and more cosmopolitan cities, it might not be easy to find the basics, especially if you are sailing down the river and while visiting the more traditional villages of the region. Your preferred brand of shampoo, toothpaste, soap, and feminine hygiene products is an absolute must. If you are prone to headaches and allergies, always choose to travel with your own supply of pain relievers, antihistamines, and hydrocortisone cream. When it comes to make-up, consider going without as it will be too hot and will tend to run. However do make sure to apply a good quality sunblock with a high SPF every two hours, especially given that you will be outdoors and under direct sunlight.
