For a comfortable and productive nocturnal expedition, we recommend: long-sleeved shirt and long trousers (light, breathable fabric), closed-toe shoes or light hiking boots, insect repellent (DEET-based or picaridin), a small personal torch or headlamp (we provide spares), a rain jacket (the rainforest can surprise you), a water bottle, and a small notebook if you enjoy recording your own observations. A camera with manual settings is a plus for nocturnal photography — we're happy to advise on settings in the field.
