Your sense of adventure and don’t forget your sense of humor. Also be sure to take along a torch/flashlight and a headlamp is good for reading and trips to visit some cool caves. Sarong, swimming suit, shorts, binoculars for the wild life, camera/video, hat, long sleeve shirt, sun glasses, sunblock, natural bug repellant just in case, your personal medications, and try to bring only natural soaps, shampoos, etc. (there are local natural products for sale). Think nature… think fun…
YOU DON'T NEED MUCH - life is simple, the weather is warm and the lake is cool.
