How do I get there?

Ok, so I'm trying to get Master Cartographer and there's a few spots I can't get to and need some help if anyone can. I am comparing my map to others that I've found and noticed that there ar a few spots I can't reach (or jsut don't know how to). The first one is an island to the east of Sanctum Cay and just south west of the ship to travel between Balthazar/LA/Kaineng. I noticed on another map that there is a small runway on the island but I have seen no quests or missions to get to it. Any opinions? The other spot is just north east of the Henge of Denravi. A very small circular area. I've tried running inside and out of the Henge and can not get to it. Anyone know where I'm talking about and how to get to it? IF anyone knows of any other tricks or what-nots to helping me gain MC title I would greatly appreciate it!

There's a whole long thread in the Tyrian Explorer's League that talks about getting the Grandmaster's title. I'm not sure how to get that spot at Henge (don't remember - LOL), and the Island is a PvP area, I'm not sure if you need it or if it's even still in use.

old pvp arenas you can't uncovrer them

cool, thanks for the info. I'll check out that thread mentioned above before I ask any more goofy questions...thanks again.
