Hi Arvon!!!
Check here:

for Xignal's excellent maps and walkthru. That should solve your problem!
Basically this puzzle consists of getting from the NW section to the SW section and the best "logic" to use is reverse logic. Xignal's walkthru will get you through in a breeze but if you want to give it a try again on your own - head in the opposite direction of where you want to be!
Hope that helps!
