Stick with Penemu (recently changed name to Piaynemo). Wayag has a better top site view, but much harder to get to the top. It has no wooden stairs all the way to the top like in Penemu.
I’m a bit of adventurous, so I like doing this easy rock climbing to the top of Wayag, but you definitely need to be very very careful. it has sharp limestone rocks that could easily cut / badly injured you if you slip & fall. You are in a remote island in the middle of no where.
Wayag underwater side is just OK. Nothing like Melissa’s Garden in Penemu. You won’t miss much for not going to Wayag IMHO.
