Arrival date in Phong Nha
After arriving in Dong Hoi City by plane/bus/train, you can transfer to Chay Lap Farmstay by Oxalis Adventure's shuttle bus free of charge or by taxi (see Arrival Departure Guide here). If you transfer with our shuttle bus, departures are at 6:30 and 14:00 daily. You will reach Oxalis Adventure’s office in Phong Nha first, then Chay Lap's transport will bring you to the resort. Don't miss the opportunity to cycle along the rustic countryside, kayak on the Chay River, or experience an herbal sauna to enjoy your relaxing time at Chay Lap Farmstay. At night, you can enjoy local dishes at Expedition Restaurant (at your own expense) and rest early for a long journey awaits tomorrow.
Day 1: Chay Lap Farmstay - Nuoc Nut Cave - Hang Va Jungle Campsite
After 8:00 on departure day, our tour bus will pick you up from Chay Lap Farmstay for the drive to the Oxalis office. Here you will have a tour safety briefing, sign the release form, and receive the required equipment for the tour.
The route starts with a short steep drop down from the road to the valley floor.
A nice easy half-hour trek in the forest brings you to a dry rocky stream. Follow the rocky path carefully to climb down over boulders to the 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 water-filled passage. Take the passage connecting to Hang Va on the return and join in activities such as scramble through narrow passages, admiring unique stalactites, or take a plunge into the natural pool lies beneath the ground. Another 100m of swimming with a lifejacket and guideline leads to a climbing point. Harnesses will be used to climb out of the entrance to the camp. If water levels are high, head back to Nuoc Nut entrance. A short steep rocky hill and descent will then bring you to the campsite. Enjoy dinner served by your team, and the experience of a night deep in the jungle.
Day 2: 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 the 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 as 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 at around 17:00. You will be transferred to your hotel in Phong Nha, or you can stay at Oxalis Home to take a hot shower and get change before your next destinations.
