Actually, we had no guide when we went there and a guide is not needed. The trail to the summit is easy to follow. All you’ve got to remember is the jump-off point, which is the block before the DENR Station. Then at the assault (few meters before the camping ground), you’ll encounter a big rock, the way is on the left. And if ever, there are a lot of hikers in the area. You won’t get lost :)
