Near the site of Neak Pean, there are two small temples Prasat Prei and Banteay Prei which are away from the road and therefore very little visited. They even seem completely abandoned, Prasat Prei. it is just a small Gopura (entrance tower) which balances on a small mound of earth, which literally fall into ruin. . The tour lasts no more than 5 minutes as there is not much to see. Banteay Prei, the "Citadel of the Forest", is a small Buddhist temple late 12th, early 13th-century, it 's a forgotten temple of Angkor. . It was built during the reign of Jayavarman VII and is stylistically similar to nearby Preah Khan and Ta Prohm temples. The temple is not very large. justf a few tens of square meters, where vegetation has fully recovered. The perimeter gallery through which you must pass is inaccessible by places as soil and stones has accumulated inside. You must get down to your hands and knees to visit. After making your way between the stones, you come to a small square, completely hidden from outside view. There are some fragile buildings with very beautiful bas reliefs, and vegetation that grows everywhere.  This temple is probably the wildest in the whole city of Angkor, you can visit it without meeting anyone To do If you have adventurous spirit.

And as such you may skip it in favor of the other Temples in the Siam Reap Area. Even if you are there for several days or e week, there are still many more interesting attractions. The only positive side probably is that you will be completely alone there, no tourists, no pushing, no line for pictures. Just you and the nature and the Temple. So may be after all, if you're in it that could be something you'd like to do/
