ABOUT YOUR DESTINATION
Phong Nha is a haven for adventure seekers. Its location in central Vietnam requires more time and effort to reach, probably why fewer travellers make their way to this town. That means you can enjoy a mostly unspoiled bit of paradise when you visit Phong Nha-Ke Bang National Park.
This UNESCO World Heritage site is known for its enormous cave system — which includes the world’s largest cave (Hang Son Doong) and the longest dry cave in Asia (Paradise Cave). Outdoor lovers will also enjoy the lush hiking trails, karst mountains, and amazing wildlife in Phong Nha.

Used the Songserm ferry from Koh Samui. Cheaper than Lomprayah but takes a bit longer. Still a perfectly fine crossing. The views approaching Koh Tao are stunning either way.

Train via Surat Thani was our pick. More scenic than Chumphon route and the Lomprayah catamaran from Tapee Pier is very comfortable. Book the special express train for the quickest ride.
The overnight bus with Montanatip was okay but not great. The bus was older and the seats didn't recline much. Ferry portion was fine though. If you're on a tight budget it works.
Took the sleeper train to Chumphon — magical! Woke up to palm trees and transferred to the Lomprayah catamaran. Whole journey felt like an adventure.
Lomprayah bus+ferry combo from Khao San Road was seamless. Departed at 6am, arrived Koh Tao by 3pm. Well organized.
Flew to Koh Samui and took Lomprayah catamaran. More expensive but saved a full day. Worth it if your holiday is short.
Most travelers base themselves near the main beach for easy access to transport, restaurants, and activities.
Thanks to the great hospitality of the family, Thao Nguyen Homestay will feel like your home. After a day of trekking, you can take a dive in the pool or sit back and relax with a Netflix movie.
The homestay is located right in front of the bus stop in the centre of Phong Nha. The rooms are bright and spacious, with some of them offering spectacular views of the mountains.
You'll probably find it slightly hard to believe that rooms also start at $16 at Phong Nha Dawn House. This place has an almost perfect rating for a reason.
Tu Tu and her family make you feel right at home in their beautiful homestay where you can enjoy a refreshing swimming pool, delicious restaurant and comfortable rooms.
Floating in an infinity pool overlooking endless rice fields, can you think of anything better? How about if on top of that, there are mountains in the background and you're staying with a beautiful Vietnamese family?
Karst Villas offer all of that plus modern room and unique bathrooms. A very memorable stay!
