Black Eagle Viewpoint

A free roadside lookout in the Pak Phli hills of Nakhon Nayok draws birdwatchers for the seasonal arrival of migratory black kites (เหยี่ยวดำ, Milvus migrans lineatus) — the raptors the Thai name refers to, though this page’s English name follows a common “black eagle” translation of that name rather than the true black eagle species. The viewpoint looks out over forested hills on the southern fringe of the Dong Phayayen–Khao Yai Forest Complex, a UNESCO World Heritage site.

Flocks arrive from Russia, China, Mongolia, Korea, and Japan roughly between November and March, riding the thermals that rise off the valleys below in numbers that local birdwatching reports describe as running into the thousands during peak weeks. Locals point to the stretch from around 3pm to sunset as the most active viewing window, when the kites wheel over the ridge before settling for the night. Outside the migratory season the site is a much quieter forest overlook, worth visiting for the view rather than a guaranteed raptor show.

The lookout itself is a simple platform reached by a short walk from a rural road — there is no visitor centre, ticket booth, or paved car park, so treat it as a local nature spot rather than a developed attraction. Bring binoculars if you have them; the kites typically circle at height rather than close overhead, and a scope or a long lens improves the experience considerably.

Insider Tip: Aim for a weekday during the November-March window and arrive by early afternoon to claim a clear sightline before the light softens toward sunset — this is when both the numbers and the photography conditions peak together.

Watch out: The site has no shade, shelter, or facilities, and the approach road can be easy to miss without a GPS pin. Carry water and sun protection, and don’t expect food or drink vendors nearby.

Pak Phli district holds several other low-key Nakhon Nayok sights worth combining with a visit, including the Khun Dan Prakan Chon Dam and the cascades at Namtok Sarika, both within a short drive.
