Cat Tien NP mammal records (Vietnam, 2024).

SUMMARY: On two trips to Cat Tien (Jan 2012 and Dec 2024) I saw 21 mammal species. The highlights in 2024 were Southern Pygmy Loris, found on my third night of searching after not finding it in 2012, and Thick-thumbed Myotis. Reptiles included Ruby-eyed Green Pitviper and Banded Krait.

E.  SITE AND TRIP INFORMATION

Trips: (1) 27-31 Jan 2012 and (2) 10-13 Dec 2024. I travelled with Chi Phan but I did night walks alone. On both trips we stayed at Forest Floor Lodge in the park.
Cat Tien NP is accessed by an 80m ferry ride starting here (11.423328N, 107.430351E). This takes you the park HQ and accommodation area. There is a restaurant here.
Forest Floor Lodge (11.435685° 107.428414°) is about 1.5 km north of the HQ area. You can book it directly or on agoda.com. Our room had fan and air-con for limited periods; the lodge runs on solar power and limited generator use. There is also safari-tent accommodation. The restaurant area overlooks the river; we ate most of our meals here.
Trails: In 2024 I was targeting the Pygmy Loris and concentrated on (1) the bamboo dominated areas on Dac Lua road between HQ and FFL and (2) the area around the Heaven Rapids track T-junction off Dac Lua Road (11.439360° 107.426460°; it is 440m NNW of FFL). The trailhead for “Botanical Garden Trail 1” is 300m north of FFL. I walked the trail to Crocodile Lake in 2012 but not in 2024.
