There are 2 easy ways, either you go at Taverly the druid village and follow the mountain from the very south to the very north of the village, you will eventually find an path into the mountain. Just follow it and dont get lost too much, it will lead you to the other side. Watch out for wolves. The other way is simply taking the boat, take a boat in port sarim to karamja and walk to brimjaven (use a world map to help you) and there take the boat to ardougne, or you can simply use the charter boat from port sarim to ardougne but its costier Hope this helps =) And welcome to Tip.It forums :D
