Only 86 remain in the entire Mekong River. All of them live in nine deep-water pools between Kratie town and the Laos border. These are the last freshwater Irrawaddy dolphins (Orcaella brevirostis) on Earth – ancient-looking, round-faced creatures that locals call “the river’s wise elders.” Here’s everything you need to know about seeing them responsibly in 2025.
Where They Live – The Nine Sacred Pools
- Kampi Pool (15 km north of Kratie) – the most reliable, 20–35 dolphins
- Anlong Koh Kong – second-best, quieter boats
- Prek Prasab – seasonal, best Nov–Feb 4–9. Stung Treng stretch – fewer sightings, longer boat ride
The dolphins stay in these 30–50-metre-deep pools year-round because the Mekong’s main channel is too shallow outside the wet season.
Best Time to See Them (2025)
- December–May (dry season) – water clearest, dolphins surface more often
- 6:00–9:00 a.m. or 3:00–5:30 p.m. – coolest, calmest, most active
- Avoid 11 a.m.–2 p.m. – heat haze and boat traffic
How to See Them Ethically
- Use only community boats from Kampi village pier (US$9/person or US$40 private boat) – money goes directly to former gill-net fishermen now protecting the dolphins
- Kayak tours with Sorya Kayaking (US$25–35) – silent, zero engine noise
- No swimming with dolphins (illegal since 2018)
- Boats must stay 50 metres away and cut engines when dolphins surface
The Conservation Story
- 1997: 200 dolphins
- 2015: 80 dolphins
- 2025: 86 dolphins – first increase in 30 years!
The turnaround came from:
- Replacing deadly gill nets with eco-tourism income (US$1.5 million/year for 300 families)
- WWF ranger patrols removing illegal nets
- Community “dolphin guardians” who report sightings via WhatsApp group
- New 2025 drone monitoring project tracking mothers and calves
What You’ll Actually See
Irrawaddy dolphins are shy and slow-moving. They surface every 30–90 seconds for a gentle puff of air, often in pairs or family groups. No leaping like ocean dolphins – just graceful arcs and that characteristic “melon” forehead. Calves (born Dec–May) ride on their mother’s back – the cutest thing you’ll ever see on the Mekong.
The Best Experience in 2025
Book the Kampi Community Dawn Patrol (5:45 a.m. departure, US$40 private boat). You’ll be on the water as the sun rises red over the river, mist swirling, and the first dolphins appear like ghosts in the golden light. The boatman will cut the engine and drift – sometimes dolphins swim within 10 metres. Bring a thermos of Khmer coffee and just listen to the river breathing.
The Irrawaddy dolphins aren’t a tourist attraction. They are the last living link to a Mekong that once teemed with life. When you watch one surface and exhale, you’re not just seeing a rare animal – you’re witnessing a miracle of community conservation that turned former poachers into protectors. In a world losing species daily, Kratie’s dolphins are proof that sometimes, with enough heart, we can still save what’s left. Come quietly. Leave changed.
