Top 10 Lighthouses in Thailand
Thailand's maritime geography divides cleanly into two distinct sea environments: the Andaman Sea coast to the west, open to the Indian Ocean and subject to the southwest monsoon, and the Gulf of Thailand coast to the east and south, a semi-enclosed shallow sea that experiences different weather patterns and different hazards. The kingdom's lighthouses reflect this duality — the Andaman coast lights mark rocky headlands, offshore reefs and the approaches to Phuket, one of Asia's busiest yacht harbours and a major cruise terminal, while the Gulf lights guide the enormous tanker and container traffic serving the port of Bangkok and the oil terminals of the eastern seaboard. Thailand was never colonised, and its lighthouse service developed independently, drawing on European maritime technology without the colonial infrastructure of neighbouring Burma and Malaya. Thai lighthouses tend toward functional modern structures, but several heritage towers and strategically significant positions make the circuit rewarding.
1. Phromthep Cape Lighthouse, Phuket
The Phromthep Cape Lighthouse at the southern tip of Phuket Island is the most celebrated maritime landmark in Thailand, set on a dramatic headland of pink granite above one of Asia's most photographed sunset vistas. The white conical tower was built in the 1990s to mark the rocky southern extremity of Phuket and to guide vessels entering the Andaman Sea approaches from the south. The cape lighthouse stands about 18 metres tall and displays a flashing white light with a range of around 15 nautical miles, warning of the shallow ledges extending south from the cape into the passage between Phuket and the Phi Phi Islands. An elephant shrine and viewing pavilion now surround the lighthouse, and thousands of visitors gather here each evening for the sunset. Despite its tourist surroundings, the lighthouse performs a genuine navigational function for the Phuket area's heavy yachting and dive-boat traffic.
2. Laem Phra Chedi Lighthouse, Ranong / Phang Nga Province
The lighthouse at Laem Phra Chedi, on the cape between Ranong and Phang Nga provinces on Thailand's upper Andaman coast, marks one of the narrowest and most navigationally complex stretches of the Thai coast — where the numerous islands, reefs and tidal channels of the Mergui-adjacent archipelago begin. This part of the Andaman coast sees heavy fishing vessel traffic and is a major transit route for traditional wooden fishing boats working between Thai ports and the offshore fishing grounds near the maritime boundary with Myanmar. The lighthouse is maintained by the Royal Thai Navy's Hydrographic Department and is not generally open to casual tourism, but the cape offers dramatic views of the island-studded seascape that extends northward into the Kawthaung area of Myanmar.
3. Koh Lanta Lighthouse, Krabi Province
At the southern end of Ko Lanta Yai, the main island of the Ko Lanta archipelago in Krabi Province, a lighthouse marks the southern exit of the Ko Lanta Channel — the passage between the island and Ko Lanta Noi that separates the open Andaman Sea from the sheltered inshore route between Krabi and Trang. The lighthouse is a slender white tower of modern construction, standing on a steep headland above the sea at the island's forested tip. The surrounding Ko Lanta Marine National Park protects the waters around the southern islands, and the lighthouse headland has a small viewpoint accessible on foot from the nearest village. Ko Lanta's southern lighthouse is a pleasant excursion for visitors based on the island, reached by a scenic drive through the national park.
4. Sichang Island Lighthouse, Chonburi Province
Ko Si Chang in the upper Gulf of Thailand, just off the coast of Chonburi Province east of Bangkok, is a small rocky island with a lighthouse of considerable strategic importance. The island sits at the approach to the shipping channel leading into Bangkok and the Laem Chabang container terminal — Thailand's primary container port — and the Si Chang lighthouse guides the enormous cargo ships and tankers that must navigate the shallow, buoyed channel through the upper Gulf. Ko Si Chang was historically important as a royal retreat and trading anchorage, and King Chulalongkorn (Rama V) maintained a summer palace on the island; the lighthouse dates from the same reforming era in which Thailand modernised its maritime infrastructure. The island is accessible by ferry from Si Racha and offers cycling and a glimpse of an island barely touched by mass tourism.
5. Ko Samui Lighthouse, Surat Thani Province
Ko Samui, Thailand's second-largest island and a major tourist destination in the Gulf of Thailand, has a lighthouse at its northern tip that marks the approach to Nathon Pier and the ferry routes between Samui and the mainland ports of Surat Thani and Don Sak. The northern tip of Samui is a headland of considerable navigational significance because it marks the entry to the Ko Samui/Ko Pha Ngan channel system, where the tidal currents and ferry traffic create a genuinely complex small-craft environment. The lighthouse is a modern tower and primarily functional in character, but its position above the rocky northern cape gives it a scenic setting typical of Samui's landscape of palm-covered hills above turquoise water.
6. Koh Tao Lighthouse, Surat Thani Province
The remote northern island of Ko Tao, renowned as one of the world's most popular scuba diving destinations, has a lighthouse at its northern tip that guides liveaboard dive vessels and inter-island ferries through the passage between Ko Tao and the larger Ko Pha Ngan to the south. Ko Tao's waters contain extensive coral formations and the lighthouse marks the safe approach for vessels anchoring off the island's northern dive sites. The island is accessible only by overnight ferry or high-speed catamaran from Surat Thani, Chumphon or Ko Samui, and the lighthouse is visible from the boats as they approach. The northern tip of Ko Tao offers a short hike to the lighthouse headland with panoramic views of the surrounding Gulf islands.
7. Pattaya Harbour Light, Chonburi Province
The resort city of Pattaya on the eastern Gulf of Thailand coast has a harbour light marking the entrance to the commercial fishing pier and the speedboat piers that serve the offshore islands popular with day-trippers. While Pattaya is best known as a beach resort rather than a traditional maritime town, the harbour handles a large volume of tourist boat traffic to Ko Lan and other offshore islands, as well as fishing vessels and occasional small cargo traffic. The harbour light is a functional modern structure, entirely pragmatic in character, but it reflects the enormous growth in coastal recreational boating that has accompanied Thailand's tourist boom over the past four decades.
8. Songkhla Lighthouse, Songkhla Province
Songkhla, on the narrow isthmus between the Gulf of Thailand and the large brackish Lake Songkhla, is the southernmost significant port on Thailand's Gulf coast. A lighthouse at the entrance to Songkhla Harbour guides fishing vessels and cargo ships through the channel between the sandy spit and the rocky headland that frames the port entrance. Songkhla is one of Thailand's oldest port towns, with a history of Chinese, Malay and Portuguese influences visible in its architecture, and its lighthouse has served the long-established fishing fleet that operates across the Gulf. The town's old quarter, museums and lakeside setting make it one of the more atmospheric stops on the southern Gulf coast.
9. Prachuap Khiri Khan Light, Prachuap Khiri Khan Province
The narrow coastal plain at Prachuap Khiri Khan, where the Gulf of Thailand coastline pinches close to the Burmese border, has a lighthouse associated with the small port at the base of the dramatic limestone outcrop of Khao Chong Krachok ('Mirror Mountain'). The light guides fishing vessels and occasional cargo craft into the shallow bay and marks the coast for vessels navigating the narrow passage between the Thai mainland and the offshore banks. Prachuap Khiri Khan is a quiet Thai provincial town that sees relatively few international tourists and retains a relaxed fishing-town character, with excellent seafood and a famous monkey-inhabited limestone hill. The lighthouse adds a maritime note to a town whose identity is shaped by the sea.
10. Hat Yai / Pak Bara Light, Satun Province
The Pak Bara ferry terminal in Satun Province serves the islands of the Tarutao Marine National Park — Ko Tarutao, Ko Lipe and the surrounding protected archipelago — and a lighthouse near the terminal mouth guides the ferries that link these islands to the mainland. Ko Tarutao has its own dark history as a political prison island during World War II and subsequently as a pirate base before the national park was established in 1974. The light at Pak Bara marks the beginning of one of the most beautiful seascape routes in Southeast Asia, with the limestone islands of southern Thailand and northern Malaysia rising from a shallow emerald sea.
Practical Information
Thailand's lighthouse circuit is best divided by coast: the Andaman coast lights (Phromthep, Ko Lanta) are best visited in the dry season between November and April, when the southwest monsoon has ceased and sea conditions allow easy access to the headlands and offshore islands. The Gulf coast (Si Chang, Ko Samui, Ko Tao) has its own monsoon rhythm running roughly opposite to the Andaman side, with the peak tourism season from December to March. The Royal Thai Navy's Hydrographic Department maintains navigational information for Thai waters; for foreign visitors, the most practically useful overview of where lights and hazards are located is the interactive chart available through Open the map, which plots all charted aids to navigation on both the Andaman and Gulf coasts.
