What do we need to bring?

Not much. Keep clothes light and maybe a rain poncho just in case we get a shower, bug spray and sunscreen. A headlamp for night walking or bike riding would be advisable. Sandals and another pair of comfortable walking shoes that you are not afraid to get dirty. Hiking boots are overkill here and usually too hot. We have secure locked storage for cameras, passports, etc. If you feel moved, you can bring something for the local indigenous communities, as I mention below.
