Cat Tien National Park Crocodile Lake, nestled deep into the UNESCO-recognised world biosphere reserve, is only accessible by a 10km pick-up truck ride and then a 5km hike. The Crocodile Lake or Bau Sau in Vietnamese is situated in Cat Tien National Park, Dong Nai Province. We had spent a remarkable morning trekking through 15km of rainy jungle within the park.
With water boots, long sleeves and pants, and heavy douses of bug spray our five-member group and tour guide from the park’s eco-tour service centre, were well prepared for the snakes, mosquitoes and terrestrial leeches populous during the rainy season (between late June and November).
The Cat Tien national park hiking trip was made easier by the thick umbrella of trees above, sheltering us from the rains. At one point, alerted by the strong smell of urine, we became aware of some langur and gibbon monkeys searching for food overhead.
We stopped several times to snap photos of the green scenery and stamp out a few leeches. Finally, after two hours of wearing out our shoes, we arrived.
The Crocodile Lake is the biggest one in the lagoon system with its 2,500ha area of water in the rainy season. The lake was once home to crowds of fresh water Siamese crocodiles, but the species dwindled to near-extinction due to illegal hunting and human activities. Now, the fresh water crocodile species has recovered considerably after 60 individuals were released with the support of a conservation project in 2000.
Even though the crocodiles are best seen around 8am or 5pm, we decided to explore the lake anyways. Hard rains prevented us from venturing out in boats to get closer to the crocodiles, but we could still see crocodiles swimming about 50m from our station shelter. One of the bigger crocodiles, about 2m long, came close to the station as it searched for prey near a grassy plot.
Ranger Linh said, “The fresh water crocodile often reproduces once a year, laying about 40 eggs each. A junior crocodile can grow as long as 25cm and seek food themselves.” He said the reproduction rate of crocodiles is only around 40 per cent due to climate change, lack of food and male crocodiles killing junior crocodiles to stop female partners from spending too much time caring for the adolescents.
The female crocodile is very aggressive about protecting its eggs and offspring, he said, therefore the males urge their partners to move onto the next reproductive turn.
According to park officials, 25,000 tourists have visited the park this year, 5,000 of them foreigners. Tourists can also visit the park’s wildlife rescue centre home to 35 bears, gibbons, leopard and langur monkeys. Cat Tien national park tours should be booked in advance.
