On RuneScape how do you get to Crandor

There are a few ways to go there. One is through the boat which you repair (one time two way) as well as by taking a boat to karamaja and walking down a "tunnel" where you meet (in order) skeleton, red spider, lesser demon, skeleton, and if you want elvarg you will find it there. I cant remember which direction it is but it is just after an area with monkeys and snakes if you walk from general store. The entrance is at the top of the crater.
