Adventure tips

Start EarlyPickups typically begin pre‑dawn—eat a light breakfast and bring caffeine; mornings are when wildlife is most active.

Bring a Waterproof LayerTropical storms can arrive fast—pack a breathable rain jacket and protect electronics in dry bags.

Footwear and GripWear sturdy, grippy trail shoes to handle steep, rooty, and often muddy trails; sandals are not recommended.

Respect Wildlife DistanceLet the guide set the approach distance to orangutans—close approaches stress animals and are unsafe for you.

Recommended gear

Sturdy trail shoes: Essential for traction on steep muddy slopes and root networks.
Light waterproof jacket: Protects against tropical downpours common year‑round, especially in the monsoon months.
Insect repellent with DEET or Picaridin: Reduces mosquito and leech bites during long periods in dense forest.
Daypack with dry bags: Keeps water, camera and spare clothing dry during river crossings and rain.
