Among the Bakun Trio mountains, Mt. Tenglawan is the most difficult to hike because of its long terrain and an assault, although its trail class and technicalities can be placed at a moderate level. This mountain might be a challenge for some hikers, yet it has an amazing shape from afar. Not only that, the trails are covered with luscious green, colorful ornamental plants, trees, and, more importantly, the birds were singing like they were part of a musical orchestra.
