The Expedition
Ten days disappear fast when you are shoulder-deep in one of Southeast Asia’s lushest rainforests. Serpentine Expeditions threads Sumatra’s lowland and montane trails in search of king cobras, reticulated pythons, pit vipers, flying frogs, slow lorises, orangutans, and the seismic presence of wild Sumatran elephants. Andrew joins as a photography-minded field partner: lighting discipline, respectful distances, and coaching for humid-lens realities. Nights belong to tracks in the mud, red flashlights, and the adrenal hush when a big snake clears leaf litter nearby. Days swap between river corridors, fruiting figs, and viewpoint hikes. This is not a luxury safari — it’s an expedition for people who want their boots dirty and their memory cards full.

Before you go
Questions, answered
How experienced do I need to be in the water?
Requirements vary by expedition — most trips ask for strong, confident open-ocean snorkeling rather than a dive certification. The quick facts at the top of this page list this trip's honest prerequisites; if you're unsure where you stand, ask before you reserve.
Do I book this trip here or with a partner?
Follow the reserve button in the dates section above — it always reflects how this expedition is sold. Some trips take a deposit directly on this site; others book through a partner operator like Serpentine or One Ocean, and the button links out when they do.
How do deposits and balances work?
For trips sold via this store, a deposit reserves capacity on published trip dates; balance terms follow your confirmation and trip packet. Partner-booked trips follow that operator's policy.
Is travel insurance required?
Yes. Medical, evacuation, and trip cancellation coverage is required before departure on expeditions Andrew leads or co-promotes. You'll be asked to certify coverage.
What if weather or wildlife don't cooperate?
Wild animals and ocean conditions owe us nothing. Briefings prioritize safety and ethics first — itineraries flex. Some days stay quiet; others rewrite your archive.
