If you have the Ragnarok, just get out like you usually do. Make sure you're near the ground or it won't let you out. I don't think you have to do anything special before to go on the island, but I don't know cuz I went to them later on in the game. But everyone else is right, they are hard. ONLY if you're not on a good level though. I find the Island Closest to Heaven is easier, but the hell island has better items to get from the ememies, BUT WATCH OUT FOR MARBOROS!!! They're on BOTH islands. Oh and the draw points are invisable. They have really good spells like Meteor, Ultima, Aura ect, so just run around the coastline of the whole island and keep clicking. Good luck!!!
