Hm...most of the dragons in Dragon's Den are wild, so it is hard to tell. From what I can assume the oldest dragon is Ace Trainer Kobe's Dragonair, since it is the highest known leveled Pokemon in the area. Or, perhaps the oldest dragons are the level 40 Dragonairs, which are very rarely encountered when using a super rod.
-It is extremely dangerous to go into a dragons den. What were you thinking? I'm not going to tell you. I think you're highly irresponsible. -Yes, because dragons are real and everything, right? Really, you must defeat Clair of Blackthorn City. Even when you beat her, she will not give you your 8th gym badge. She will on the other hand, give you an assighment that takes place in the Dragon's Den. Because you have her permission, you can enter Dragon's Den.
After you battle with your rival at the Dragon's Den he shows up when you're climbing the stairs to battle the Pokemon League again
gym leader Clair the 8th gym leader in soulsilver gives it to you after the dragons den quiz
Surf to where the Dragon's Shrine is...when you reach it don't go in but continue foward...after you pass the shrine go back up towards the top of the screen and there will be a staircase on the right...the dragon's fang is at the top
surf to this little training house but a whirlpool is in ur way so use whirlpool to get passed it then answer some qeustions the master asks u and u will get the final badge,then later when u beat the entire game(even kanto) if u go back to dragons den u can get a free dratini!

Beat the eighth gym leader, then she will tell you to go into the dragons den before she gives you the badge.
Well there aren't probably any dragons alive today (but they have existed), so there is no such thing as dragon den's anymore. But It's probably a large cave.
