Travel Guide: Lussok Cave and Underground River
Luna, Apayao, Philippines — Somewhere between the mountains and the sea of the great Cordillera Administrative Region are quaint, quiet towns—little treasures tucked away in its vast expanse, like Luna in the province of Apayao.

Road trip to Apayao from Cagayan Valley
Looking back, it has been more than a decade since I last set foot in the province. I was surprised to see many positive developments, and the roads are much better than those in other provinces in Luzon, despite being one of the region’s lesser-known tourist destinations.
To me, it was impressive how local officials have been pushing their tourism promotion efforts to help the livelihoods of their community.
A landlocked area in the Philippines that borders Cagayan to the north and east, Abra and Ilocos Norte to the west, and Kalinga to the south, Apayao is naturally traversed by rivers and is home to several natural attractions frequented mostly by local backpackers. It is considered Cordillera’s last natural frontier because its people still maintain their peaceful coexistence with the natural environment.
Nestled in the northernmost part of Apayao is the municipality of Luna, where the Lussok Crystal Cave and Underground River are emerging as an eco-tourism hotspot.

Our Media group and the rest of the Grand North Luzon Caravan participants have just visited St. Philomene Church in Alcala, a town in the northern province of Cagayan. Our next stop was strategically the nearby municipality of Luna in Apayao. It was almost sundown when we arrived in the area, and we proceeded to the Lussok Cave Visitors Center for a late lunch and activity orientation.



Upon arrival at the area, we were welcomed by the Provincial Tourism Officer, Ms. Rebecca Mamba, and Apayao Board Member, Ms. Kyle Bulut. We were also welcomed by the Provincial Government of Apayao cultural group, who performed their traditional dance [taddo’] and even invited some of us to dance with them.

Unknown to most of us, their performance is just the beginning of a one-of-a-kind journey we are about to embark on.
About Lussok Underground River and Crystal Cave
On the rocky slope of Barangay Dagupan, one will find this multi-chamber cave with centuries-old stalactites and stalagmites, embedded with crystals that dance and shine with the tiniest reflections of light, hence its other name, the Crystal Caves.
TRIVIA: Lussok means a hole in the Ilocano language. The cave was named as such due to a hole that provides light inside the cave.

Accessible via an underground river system, you can navigate the calm, placid river and reach the picturesque maze by boat without outriggers (or katig).


The cave is a 20-minute drive away from Marag Valley. A short walk from the visitor’s center leads to the river cruise jump-off point. The tour starts with a brief 200-meter boat ride on the enchanting azure waters.



During the 10-15-minute river cruise, we were in awe of the lush vegetation, crystal-clear waters, and the overall serenity of the place. Glimmering limestone formations reflected the light seeping through the formation and welcomed us just before we reached the mouth of the cave.



Inside, you will see various formations of stalactites and stalagmites, much like the ones in Puerto Princesa in Palawan. There are formations depicting the Blessed Virgin Mary, vegetables, fruits, and faces, all pointed out to us by our trained boatmen guides.


For thrill-seekers, you can also go on a one-hour guided spelunking activity up to its vertical cave.
