When visiting Coral Island, be prepared for a day of outdoor activities, so pack essentials like sunscreen, a hat, and swimwear. The waters are ideal for snorkeling, but if you plan to explore the coral reefs, consider bringing your own equipment, or you can rent gear on Koh Larn. There are limited amenities on the island, so it’s a good idea to bring snacks and plenty of water. Also, as the island is relatively untouched, make sure to take care of the environment and avoid touching or disturbing the coral reefs.

Coral Island is located just a short boat ride away from Koh Larn. The easiest way to reach the island is by taking a long-tail boat from Koh Larn's main pier, which typically takes around 10-15 minutes. Boats can be rented for a round-trip or for a day’s excursion. You can also book tours that include transportation to and from the island, with activities like snorkeling or diving. If you are staying on Pattaya, it’s possible to arrange a day trip to Koh Larn, and from there, you can easily catch a boat to Coral Island.

The best time to visit Coral Island is during the dry season, which runs from November to April, when the weather is sunny and calm, perfect for water activities. During this time, the sea is clear, offering excellent visibility for snorkeling and diving. If you prefer a quieter experience, try to visit during weekdays or early in the morning to avoid crowds. During the rainy season (May to October), the weather can be unpredictable, with occasional storms, and visibility for water activities might be lower.

Coral Island is a fantastic day trip from Koh Larn, offering a day of exploration, relaxation, and adventure. After a short boat ride, you can spend your day snorkeling, swimming, or enjoying the peaceful surroundings. If you’re interested in more adventure, you can take part in water sports activities like jet-skiing or parasailing. You can also plan a visit to Koh Larn's other popular beaches, such as Tawaen Beach or Samae Beach, after your trip to Coral Island. For a complete experience, some tours offer combined packages to both islands with lunch included.
