Calculate your Koh Larn trip cost
Start with the operator-posted public-ferry fare, then enter the quotes and spending limits that apply to your own trip. The calculator does not present unverified island prices as current facts.
Enter a per-person plan
The public ferry was posted at 40฿ each way when checked on 23 August 2026, so a 80฿ return is pre-filled. Food, island transport, rooms, rentals and activities vary by operator and date; those fields start at zero for you to replace with a current quote or personal limit.
