Tu Lan 4-day expedition tour (4 Days - RT051)

Tour Code: RT-051
Duration: 4days/3nights

This skills-based caving adventure provides a highly informative insight into this unique caving region, home to the most spectacular caves and jungle of Vietnam!

On this 35 km tough jungle and cave trek there is plenty to keep your heart racing with some dark cave abseiling, bouldering,climbing and a lot of swimming through the caves. Our secluded jungle campsites are spectacular and mostly different from those visited on our shorter treks in the same region.

Our Tu Lan Expedition will take you to Hang Tien Cave, one of the largest caves in the region, and with your caving expert you’ll explore up to 2 km of this huge and impressive cave, which is certainly a highlight of the expedition!

The expedition takes off with pick up from your hotel in Phong Nha between 7:30 am and 8:00 am, before transferring to the village of Tan Hoa.

A 2 km trail leads the ways to Mango Mountain, where lunch will be served picnic-style. It’s 2 km more to Tu Lan Valley and then arrival at Tu Lan Valley campsite for swimming around the cooling waterfall before a well-earned dinner with the team.

Adventure Level

The Tu Lan Expedition is moderate-to-hard for anyone who considers themselves physically fit and who participates in regular outdoor activities, and not suitable for those without trekking experience. You will trek approximately 30 km via overgrown jungle paths and valleys, and scramble over many boulders within the caves. You should be able to swim as you’ll explore a number of wet caves, up to 1.5 km in some cases. You should also feel comfortable having to climb through some small passages, and also up/down a 15 m ladder (with safety rope). You will be abseiling inside the cave, and whilst no experience is necessary, you should be ready for a tough ad tough adventure requiring both mental and physical strength.

Never forget you are deep in the jungle and the difficulty of this tour is also very dependent on the weather. It can get very cold during December to March (8 - 15 degrees Celsius) and very hot during June to August (32 - 38 degrees Celsius), not to mention anytime it rains the jungle becomes very slippery and muddy! It will certainly add to the adventure.
