Feldip hills or whatever they're called. It's South of Castle Wars. Wear full Larupia clothing, and a Spottier Cape. Everything else doesn't matter gear-wise. Bring a full inventory (leave maybe 2-3 spots empty I guess) of box traps and start hunting. If you're botting it, you will definitely need a lot of traps if you plan to camp there for a while (it loses them every now and then). If you're doing it legit, you shouldn't need many/any extra traps.
Good luck.
