Loads of fun to get to, NOT! It is an annoying maze with lots of dead ends and monsters with very little else. Look for wooden 'steps' as they can be jumped on and may lead to a shortcut of some sort. Some portions of the spiked fence can be walked on plus some are broken and can be jumped through. This is how I eventually got to the node manager and paid to 'discover' Marni's Lab. Getting out is just as bad. I got to a cliff overlooking a lake and just jumped. I landed with maybe 10-15% health left. Hopefully I never have to go there again.
