Koh Larn is a developed visitor destination, but individual shops, payment methods and beach facilities were not field-verified for this release. Pack so the day does not depend on one business being open or one payment method working.

The core checklist#

  • A practical cash reserve and a second payment method — confirm acceptance and prices rather than assuming card or ATM access.
  • Sun protection suited to you, such as a hat, protective clothing and sunscreen used according to its instructions.
  • Enough drinking water for the planned trip — do not rely on a specific beach vendor being open.
  • Any essential medication and personal medical supplies you may need before the confirmed return.
  • A dry bag or other suitable protection for your phone, documents and payment methods during the crossing and beach visit.

Add only when it fits the plan#

  • Personally fitted swimming or snorkeling equipment if you intend to use it; rental availability and condition were not field-verified.
  • Footwear suited to the route you have verified; this guide does not generalize beach surfaces or access conditions.
  • A towel and dry change of clothes if they suit your planned activities and return journey.
  • A compact personal first-aid kit in addition to essential medication; local stock and assistance were not field-verified.
  • A charged phone, downloaded route details and a power bank if you depend on the device for navigation or operator information.

Nice to have#

Optional items depend on the verified plan. Extra shade must be suitable and permitted where you intend to use it; motion-sickness medication needs appropriate medical or pharmacist advice; any food storage or insect protection should match your own needs. Do not infer beach facilities or conditions from this checklist.

What to leave behind#

Carry any identity document required by the responsible operator or authority and store originals securely; this guide does not set a universal document or deposit rule. Avoid unnecessary valuables, keep the bag within what you can manage over the route you have actually verified, and carry your own litter back out rather than leaving it on the coast.

Tip: If swimming is part of the plan, pack suitable clothing but enter only when an open marked zone, warning flags, water conditions and boat traffic are suitable. Landing on the island is not a live swimming clearance.

The verdict#

Prioritize payment backup, sun protection, drinking water, a dry bag and any personal medication. Then use the practical guide and current operator or weather notices for the parts a packing list cannot settle.
