Thank you very much Provincial Tourism of Surigao del Sur.
We are grateful for the trust and opportunity to explore and gain a deeper understanding of the caves and karst of Surigao del Sur.
Our journey began with an initial cave reconnaissance in 2025, followed by another reconnaissance in 2026, which eventually led to this year's cave expedition. In just over a year since our initial reconnaissance, we successfully conducted a week-long expedition, surveying and mapping more than 3 kilometers of underground passages. The longest cave documented in Surigao del Sur currently extends to approximately 1.5 kilometers, with the underground passage continuing beyond the surveyed section.
Beyond exploration and documentation, we also conducted coordination meetings with policymakers, municipal officials, Indigenous Peoples (IP) and local leaders, community members, and other stakeholders. These engagements are essential in fostering collaboration and strengthening collective efforts toward the understanding, conservation, and responsible management of our caves and karst.
