Koh Si Chang is the small island off Sriracha that hosts the Si Chang Scenic Trail, a run built around scenic island terrain rather than fast, flat roads. The route follows coastal paths, hills, and sea viewpoints, which makes it a draw for runners who enjoy racing in natural surroundings. Because the race starts before dawn on an island you reach by ferry, taking part means sorting out where to stay for the Si Chang Scenic Trail and spending the night before on the island.
Novotel Marina Sriracha & Koh Si Chang sits right on the island and we offer a convenient place to stay for the event. Its central location and sea views make it a comfortable choice for resting before the run and recovering after the race.

The Si Chang Scenic Trail is a trail running event set across the natural landscape of Koh Si Chang. The course takes in hills, coastal cliffs, forest paths, and sea viewpoints, so it rewards runners who enjoy island terrain over raw speed. It is organized by Road Runner Thailand and draws a field that comes for the scenery as much as the distance.

Koh Si Chang is well-suited for trail running thanks to its small size and varied natural landscape. The island covers just 18 square kilometers, yet offers many different routes and surfaces within a short distance from the mainland.
Together, these features make Koh Si Chang a rewarding location for runners who enjoy nature, scenery, and a peaceful island running experience.

The one point that shapes the whole weekend is the early start. With a 05:00 opening ceremony and a 30 to 45 minute ferry from the mainland, crossing from Sriracha before dawn on race day is impractical, so staying on the island on Saturday night is essential. For most runners, a room on the island is the best place to stay for the Koh Si Chang Scenic Trail, and because the island has limited rooms, accommodation near the Si Chang Scenic Trail books up fast on race weekend. If you are comparing hotels near the Si Chang Scenic Trail, look for a short transfer to the start, a quiet room for an early night, and an early breakfast.
At Novotel Marina Sriracha & Koh Si Chang, our rooms and pool villas sit right on the island side, overlooking the Gulf of Thailand, and we set the resort up as a calm basecamp for runners on race weekend. Our sea-view rooms and larger villas give you a quiet place to sleep before the start and to stretch out and recover afterwards, with room to spread your gear. We are within easy reach of Koh Si Chang School, where the 2027 race is based, and our team can point you to the quickest way there (please confirm the transfer time with us when you book). You can explore our Koh Si Chang accommodation to find the room that fits your group.
We build our race-weekend stays around what runners actually need:
Ferries to Koh Si Chang leave from Sriracha pier, take 30 to 45 minutes, and run regularly through the day. For race weekend, cross on the Saturday afternoon so you can collect your race pack at the school and settle in before the early start. We also run our own boat service across to the island; you can see the options on our Koh Si Chang ferry transfers page.
Once the race is done, the island rewards a slow afternoon. Relax at Tham Pang beach, visit the historical Phra Chuthathut Palace, and catch the sunset at the Chong Khao Khad viewpoint. The Asadang Bridge is a short, easy walk for a few photos. For a fuller plan of the weekend, see our 2-day 1-night Koh Si Chang itinerary.
The Si Chang Scenic Trail is a rewarding way to see Koh Si Chang on foot, across its coast, hills, and viewpoints. Staying on the island lets you rest well and reach the start without a rushed crossing, so the main thing is to secure your room early. Book your race-weekend stay with us at Novotel Koh Si Chang.
