Columbia x Oxalis: Explore The Quang Binh Cave Expedition Map (1–6 Days)

Columbia partners with Oxalis Adventure on a journey to explore Quang Binh – the “cave capital” of Vietnam. This collaboration opens up opportunities for nature lovers, trekking and caving enthusiasts to be fully equipped with outdoor apparel, footwear and technical accessories from Columbia, while experiencing 1–6 day cave tours operated by Oxalis in Phong Nha – Ke Bang and Tu Lan – Hang Tien.

When sunlight pours down to the cave floor and the underground river echoes through the ancient forest, you will understand why Phong Nha – Ke Bang and Tu Lan – Hang Tien are always listed among the world’s top adventure destinations. Quang Tri (formerly part of Quang Binh province) is home to an extensive cave system with limestone formations, underground rivers and primary forests. Routes are designed for different fitness levels: from day trips for beginners to multi–day journeys that require trekking and cave–swimming skills. All tours are operated in small groups, with strict safety procedures and a strong focus on ecosystem conservation.

With international–standard equipment, professional guides and an approach that prioritizes safety and sustainability, each journey not only helps you conquer spectacular underground landscapes but also contributes to preserving the pristine values of this heritage region.

4 - What To Pack For A Cave Tour? Columbia’s Suggested Packing List

Packing principles: lightweight – durable – quick–drying – water/stain–repellent – good traction. Prioritize gear featuring Omni-Shield™ (stain–repellent/quick–dry), Omni-Tech™ (waterproof & breathable), and OutDry™ (waterproof for footwear).

4.1 - Outer Layer (Shell) – Rainforest Showers, Splash Zones, Cave Mouth Winds

• Omni-Tech™ waterproof/breathable jacket: ideal for prolonged movement in the rain, with fully sealed seams to keep you dry (suggestions: Hikebound™ II, Northwest Explorer™ 3L Shell).
• Omni-Shield™ wind–resistant, stain–repellent jacket: versatile, lightweight, quick–drying and easy to clean off mud and dirt (suggestion: Ascender™ Softshell).

4.2 - Mid–Layer – Stay Warm During Breaks/Overnights

• Insulated/Lightweight down or synthetic jacket: prioritize high compressibility and warmth; pair with an outer waterproof shell in drizzle or fog.
• Insulated softshell pants: models featuring Omni-Heat™ Infinity (thermal–reflective lining) + Omni-Shield™ light water/stain repellency help keep you warm, dry and mobile while moving (for example: Vast Canyon™ Softshell).

4.3 - Base–Layer – Quick–Dry and Breathable

• Short/long–sleeve tees; trekking polos/shirts with breathable construction, depending on your preference.
