The whole ascent, low on the horizon. Sinnamary is the town just up the coast from the launch complex, on the far side of the Sinnamary river — the closest community north of the pads and a quiet alternative to Kourou.
Liftoff itself is behind the curve of the Earth, but the rocket rises into view within seconds and you follow it for two to three minutes. Night and twilight launches are spectacular.
Look south-southeast toward the complex.
For the Carapa site or the seafront.

The whole ascent, low on the horizon. Sinnamary is about 16 miles (26 km) from ELA-4, Guiana Space Centre, bearing 126° (SE). Liftoff itself is behind the curve of the Earth, but the rocket rises into view within seconds and you follow it for two to three minutes. Night and twilight launches are spectacular.
Face SE (126°) toward Kourou. The rocket rises from that point on the horizon and arcs downrange — for Kourou launches that generally means east or northeast over the Atlantic.
Two to three minutes for the first stage, sometimes longer at night when the second-stage plume is sunlit. Twilight launches — just after sunset or before sunrise — produce the biggest, longest-lasting displays.
