Ok, coming from teh EC and facing the fp gate go to the wall on your left, follow the wall down to where there is a corner and go around the wall and in a spot you go through it. From there on its pretty easy, a bit dark though, and u will need a light source if you dont wanna get lost. You follw the LEFT side when going to NFP, you will go down and there will ber a slainted upwards hill, go up it and go LEFT and just follow the wall and whenever you can make a turn left take it. this will bring you to nfp. OOH and in a big circle room go strait through.
I thought this was all common knoledge, but decided to post it incase this could help you.
have fun.
