When I went for vacation in the Phillipines..we visit the place called Callao Cave.. Callao Cave is one of the limestone caves located in the municipality of Peñablanca, Cagayan province, most popular caves in the Philippines and the best known tourist attraction. Thats why my entry name called Callao Cabin..when I saw this place I was amazed for the greenest and calm of the environment it was amazing beautiful.. While we were in the area we tried also the the boat which made by wood and witness the scenic rocky cliffs, with clean greenish water ideal for swimming. It was co incident while browsing the internet I saw this Cabin Challenge..and the very first came into my mind is the callao cave and I was thinking that time what if I will make a beautiful cabin in this place..
