Day 1: Start exploring the Tu Lan Cave System

At around 8:00-8:30, the adventure starts from your hotel in Phong Nha by a transfer to Tan Hoa village, located 70km away. After a safety briefing and gear check, the trek begins with a 2.5 km march across fields of peanut crops, giant water buffaloes, towering corn stalks, and down to the Rao Nan River. Crossing the river and you will take a 30m ascent up a rocky hill to a small jungle and then 100m descent to reach the Hung Ton Valley.
You take a stop for lunch at Hung Ton Cave’s dry entrance, enjoying the fresh wind coming out from inside and an outstanding view of the valley below.
Leaving the Hung Ton Cave you take a hard trek over Mango Mountain to Tu Lan Valley (3 km). By mid afternoon, you arrive at Tu Lan campsite, which locates next to a small beautiful waterfall, just outside of Ken Cave. You may enjoy a shower under the waterfall, before exploring and swimming through Ken Cave. Back to the campsite you will enjoy well prepared BBQ dinner. It is perfect time to taste some local rice wine, chat with your guide and porters about their rural way of life, play funny card games or retire to your comfortable hammocks for an easy sleep under a sky of thousand stars.

Day 2: Trekking and swimming through hidden caves. Back to Phong Nha

You are waked up early by the sound of nature and enjoy a hearty breakfast in the sunrise.
In the morning you will explore the Tu Lan Cave, both wet and dry sections. The magnificence of the caves is almost indescribable. The river cave, as Tu Lan wet cave, is about 3 million years old, while the dry cave is much older, around 5 million years old. A walk through dense forest will bring you back to the campsite.
After having lunch at the campsite, you are ready for more adventure. A well combination of swimming (450m) and trekking (500m) brings you through Hang Kim to To Mo Valley and then through Hung Ton wet cave back to the cave’s dry entrance, where you had lunch yesterday. After trekking through the Hung Ton Valley, you take a climb up over a small rocky mountain to get to Rat Cave, which is about 300 m in depth. You then take a descent to Rao Nan River and cross the picturesque buffalos fields to get back to Tan Hoa village.
It is time to have a cool shower and enjoy cold beers celebrating the excellent days of adventure. You then have a transfer to Phong Nha, arriving at around 17:30. (B/L/-)
