  • Travel Cagayan Chronicles Tuguegarao And Penablanca

    Tuguegarao is a city in the land-locked region of Cagayan Valley up north (not to be confused with Cagayan de Oro down south). Bordering it are the Cordillera Mountain Range in the west, the Sierra Madre in the east, the Caraballo Mountains in the south and the Luzon straight in the north.

    It was also the first stop on my recent backpacking trip. Tuguegarao became our homebase since the tourist spot I wanted to see – the Callao Cave – is actually located in a different municipality, some 30-minute "trisi" ride away in Peñablanca.

  • Going Subterranean in the Living Sierra Cave in Penablanca

    For the more adventurous type, Sierra Cave, which is a very short distance from Callao Cave offers a lot more excitement with numerous cave formations in its pitch-black environs. We had our lunch after the Callao Cave exploration and then set off for a short hike up from the road. The cave mouth is barred with gates but since we informed them ahead, Ted was able to secure the key. Sierra Cave is one of my favorite caves because it's a perfect example of a living cave which is ideal for studying various rock formations. Below I'm sharing an excerpt from an article I wrote back in 2005 for a ma ...

  • Sierra Cave spelunking and kayaking in the Pinacanauan River

    Cagayan is positioning itself as the Caving Capital of the Philippines. And it has great spelunking options for beginners and serious cave enthusiasts.
