The whole coast here looks west across the Gulf: Pattaya Bay, Jomtien, Wong Amat in Naklua all have the sun setting over the water, which is what Pattaya does better than any other resort on the Gulf. The catch is that the central bay is a working city beach with Beach Road behind it, so the good sunset frames are at the edges — Wong Amat to the north, the Pratumnak headland between Pattaya and Jomtien, and the long, less built-up stretch from Jomtien down to Na Jomtien. Mornings are for the places that need empty space: the Sanctuary of Truth at opening, or Koh Larn before the day-trip boats. Midday is for nothing outdoors: the sun is nearly overhead for much of the year, and the beaches are at their most crowded.
Koh Larn is where the timing catches people out. The public ferry from Bali Hai pier takes about forty-five minutes, and the last scheduled boat back from Na Ban pier leaves at around 18:00 — so a sunset on Samae beach, the island's west-facing bay, means a chartered speedboat or a night on the island. Most visitors arrive via Bangkok's Suvarnabhumi, roughly two hours by road; U-Tapao, about forty minutes south, has fewer flights. The airport and the Sattahip naval area restrict drones only south of the city. For a yacht session, boats leave from the marinas around Na Jomtien and run south along the coast, so a sunset at sea is timed from the marina, not from the hotel. Allow for the traffic on Sukhumvit Road on the way.
