Reviews of Kohtour across destinations and activities, not ratings for an individual tour.
Pig Island is Koh Madsum, also written Koh Mudsum or Koh Matsum, off the south coast of Koh Samui in Surat Thani province, Thailand. Nearby Koh Tan is the usual snorkelling stop on combined tours; this Pig Island is reached from Samui rather than by a local boat trip from Phuket or Krabi.
Look south of Koh Samui for Koh Tan and the smaller nearby Koh Madsum, using the island name as well as the nickname Pig Island. English spellings vary between maps and tour listings, so match the departure area and neighbouring island before assuming differently spelled names describe different destinations.
| Map label | Meaning |
|---|---|
| Koh Madsum / Koh Mudsum / Koh Matsum | Pig Island near Samui |
| Koh Tan / Koh Taen | Neighbouring reef destination |
| Thong Krut / Bang Kao | Samui departure areas used by tours |
| Khanom | Mainland dolphin-search area |
| Phuket / Krabi | Different coast; travel to Samui first |

Published visitor guidance gives roughly 10–20 minutes by speedboat in calm conditions and around half an hour for slower boats, depending on departure and route. These are crossing estimates, not full tour durations; hotel collection, snorkelling, beach time, meals and the drive back can take several additional hours.
Travellers staying on Koh Phangan or Koh Tao need to reach Samui and the departure pier before joining these tours. Phuket and Krabi are on Thailand’s other coast, so this is not a short local excursion from either place; allow for the inter-destination journey and avoid relying on an unconfirmed same-day connection.
