Mervil getting ready for Taiwan Rechao at First Cave, Long Dong

Name: Mervil Patigdas

Hometown: Cebu, Philippines

Guiding/Climbing Experience:
When Mervil transitioned to college, he discovered running. He was not sure if he was running
towards a goal or running away from something. He just ran and he loved it. Then he discovered climbing. For whatever reasons, few years prior to discovering climbing, he signed up for a mountaineering club in his university.

It may have seemed like serendipity. But it was simple probability. He put himself in the path of good things and good things did happen. He spent the first few years of his climbing life learning the ropes. And quickdraws, and belay devices, etc. He forgot to ration his passion.

One day, Mervil just ended up as a climbing guide in Cat Ba, Vietnam. After working with Asia Outdoors for half a year, he hopped on a plane that brought him to Asia Pacific Adventures in Hong Kong. It marked the start of him working seasonal jobs and splitting his time between multiple countries in Southeast Asia and the Philippines. The technical and climbing skills he learned, he brought back to his local climbing community.

The teaching skills learned as a mentor for his local community, Mervil brought into his guiding and teaching jobs. It was a positive loop that accelerated his maturity as a climber and a climbing guide. As he went through peaks and valleys, he found himself staring at another peak: Becoming an AMGA Single Pitch Instructor. Being an AMGA instructor brought him to a new mental state. He learned a lot and discovered that there is so much more that he wants to learn. It is this guided curiosity that defines his path as a freelance outdoor professional.

Mervil is also the author of Cebu Philippines Rock Climbing Guidebook.
