Itinerary

BRIEFING: PHONG NHA - OXALIS OFFICE

Our tour bus will pick you up from your hotel in Phong Nha between 08:00 - 08:30 AM, for the drive to the Oxalis office. Here you will have a tour safety briefing, sign the release form and be provided with the required equipment for the tour.

PHONG NHA - NUOC NUT CAVE - HANG VA JUNGLE CAMP

The route starts with a short steep drop down from the road to the valley floor.

A nice easy half hour’s trek in the forest brings you to a dry rocky stream bed. Follow the rocky path carefully to climb down over boulders to Nuoc Nut Cave entrance. Enjoy a picnic lunch and then with your caving light and helmet enter into the darkness. Initially quite small the cave soon opens up into impressive dimensions. Plenty of stalactites and stalagmites can be seen on the way. After a rocky section you will meet the underground river. Follow this to the point it enters the sump, or water filled passage. Turn around and head back to the surface. A short steep rocky hill and descent will bring you to the campsite*. Enjoy dinner served by your team, and the experience of a night deep in the jungle.

HANG VA CAVE - PHONG NHA

The following morning you will have a safety briefing on how to use the harnesses and ropes.

You will then descend the steep rocky entrance using this equipment. Hang Va is a beautiful stream cave, where you will experience narrow passages, rocky climbs and some deep pools with very nice opportunities for photography. After exploring the river passage you will use your harnesses and traverse across to the high level passage using the ropes. Follow the path up into this large dry passage. Notice the huge gour dams you climb over to finally reach the amazing tower cone formations. As yet no one knows exactly how these have formed. Return the same way to camp for lunch. Trek out through the jungle over a rocky hill to another stream valley, and back to the road. Enjoy a cold drink. Transfer to Phong Nha arriving around 05:00 PM.
