Tips for Visiting Sumaco Napo-Galeras National Park
- Hire a local Kichwa or Huaorani guide to explore biodiversity hotspots - many species are only reliably spotted with someone who knows where to look.
- Plan multi-day treks: the park's cloud forest and Andean foothills change dramatically with altitude, and single‑day visits miss much.
- Bring insect repellent with DEET and sealed ziplock bags for electronics - humidity is relentless.
- Be ready for rain at any hour; quick‑dry layers are essential.
