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 treasure finds tucked hidden in its vast expanse, like Luna in the province of Apayao.
Looking back, it has been more than a decade since the last time I set foot in the province. I was surprised to see a lot of positive developments and the roads are much better than other provinces in Luzon and despite being one of the lesser-known tourist destinations in the region.

To me, it was an impressive feat how local officials have been pushing their tourism promotion efforts to help the livelihood of its local 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 nature frontier because its people still maintain their peaceful coexistence with the natural environment.
Nestled in its northernmost part of Apayao is the municipality of Luna, where the Lussok Crystal Cave and Underground River is emerging as an eco-tourism hotspot.

Our Media group and the rest of the Grand North Luzon Caravan participants have just visited the St. Philomene Church in the town of Alcala 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 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 cultural group of the Provincial Government of Apayao, 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 were about to take part of.
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 reflection of light, thus its other name, the Crystal Caves.
TRIVIA: Lussok means a hole in the Ilocano language. The cave was named as such due to a whole that provides light inside the cave.

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


The cave is a 20-minute drive away from Marag Valley. From the visitor’s center, a short walk 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 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 that were 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.
