Liveaboards Not Operating In 2025-2026 Similan Diving Season

Unfortunately several budget Similan Islands liveaboards are not operating during the 2023-2024 Similan Islands diving season (October 2022 to May 2023)

Many Similan liveaboards were mothballed during the Covid pandemic due to lack of customers, and it’s now difficult for some boats to start back up again.
