ADVENTURE LEVEL

Hang En Cave Ultimate Adventure is easy-to-moderate for anyone who considers themselves physically fit and who participates in regular outdoor activities, and moderate-to-hard for anyone with limited trekking experience. Be prepared to spend a majority of the day trekking (10 km each day), and you must be able to hike comfortably at an incline for an hour and a half (gaining over 500 m in elevation). Swimming skills are not necessary for this tour.

Never forget you are deep in the Phong Nha Ke Bang National Park 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!

Safety is absolutely paramount on all trips operated by Oxalis Adventure Tours, and along with having the best caving equipment, you’ll be led by one of our expert adventure guides. No children below 16 years of age permitted.

Start your ultimate adventure with a pickup from your hotel in Phong Nha between 8:00 am and 8:30 am and short transfer to Oxalis Headquarters.

Learn all about safety and collect your gear before driving 45 mins through the National Park to reach the trailhead. A steep jungle hill starts the adventure, with a refreshing river at the bottom. Hike through rich jungle to reach the Ban Doong minority village, where a hot cup of tea welcomes you.

Lunch takes place shortly after near the river, and then it’s back into the jungle, through river streams,and across the river valley until Hang En lays on the horizon. Enter the cave around 3 PM, and enjoy your afternoon swimming, before a sizzling BBQ dinner is served, complete with rice wine and beautiful øocks of swifts overhead.

Awake for breakfast early and explore the breathtaking exit, and then trek through the dry passage to the viewpoint high above camp, where 300 million year old fossils can be witnessed. In the late morning, trek back through the mountainous river valley, through jungle and across streams, until reaching Doong village again. Enjoy a picnic lunch by the stream and then prepare for the biggest challenge ahead, climbing the treacherous hill up to the Ho Chi Minh Road. Watch out for leeches and push ahead to the road, where cold drinks are waiting. Return by vehicle to Phong Nha by 5:00 pm.
