Bucas Grande (Sohoton Cove) is a group of islands and islets in Socorro, Surigao del Norte declared as a National Park due to its natural attractions and cultural heritage which include white sand beaches, limestone islets and cliffs, hidden coves, waterfalls, mangroves, inland lakes and colorful underwater scenery. But apart from these, the group of islands also offers spelunking on two of its caves that meet on the same opening – the Crystal and Bolitas Caves.
Crystal Cave is an open-ended cave. The name was derived due to its shining stalactites, stalagmites, columns and formations that seem to be dotted with crystals. With its big chamber and pathway, it is definitely an easy trek.
This close-ended cave is named as Bolitas, a Filipino term for pellets, due to abundance of small pellet-like stones inside. This rounded stones are droplets from tiny stalactites and believed to be formed thousand years ago.
Bolitas Cave is home to balinsasayaw, a rare bird that produces a very expensive bird’s nest that is a popular soup ingredient in Chinese restaurants.
The trek to this cave is harder than the Crystal Cave due to its small chamber and very narrow passage that can fit only a person at a time. One needs to slide, glide or crawl to get inside.
Bucas Grande is two hours by boat from General Luna, Siargao and thirty minutes boat ride from the Port of Hayanggabon, Socorro, Surigao del Norte.
