Dragon's Pass is an area, but running the seven coloured dragons (for hides and/or a DCoL) is often referred to as running Dragon's Pass, so I've listed it as both.
Follow the directions to Dragon's Pass ( 6s, ne, 2s, se, 2e, s, 2sw, s, 5sw, nw, 5n, ne, n, e, 2se ), you will arrive in the room shown to the southeast of the tan-coloured room. Be mindful that several of the rooms between the dragons' caves are tunneled, as well as the caves themselves. In the caves, however, you can kill the young dragons and fit more players in. I've listed how many people can fit in each, along with the number of young dragons in the cave.
Each of these dragons drop a piece of dragonhide and, with the exception of Black Rose, a dragon claw. If you collect all seven claws you can make a Dragon Claw of Legend. Each hide, along with a little gold, can be made into a piece of equipment by the four mobs in the town that I've pointed out. Just give the hide to its specific crafter and they will remove the necessary gold from your person and give you the equipment.

Note: beware of the Lost Mountain Troll that wanders around the dragon caves, he will join in fights and steal your weapon.
