I spent 6 months in Liberia, Uganda and Kenya and learned some things about what is helpful to bring to a tropic, hot, developing world location from the Western world. If you’re going to stay for 1 week or 2 years, take a look at this list. If you’re going for just a week or two and staying at fancy, civilized places, than you might not need all of this, but you can use your judgement.
In most places that I visited you can buy bottled water. But I had a couple times when I couldn’t and I was very thankful I had my Sawyer Water Filter. I will also say that all the bottled water had outside seals on them so you know they’re good. And they were good. Except one in Kenya, Tiji. Even though they were sealed they had floating crap in them. Yuck. I whipped out my Sawyer filter for those!
