Chocobo Dungeon

[<Sephiroth>]

Can someone give me a full guide how to enter the chocobo dungeon? I've been trying and trying with 3 level 1,2,3,4 and 5 chocobos, but I can't find the dungeon..:confused:

Did you talk to Clasko during chapter 1 or 2? Apparently, the Chocobo Ranch is inaccessible if you miss that.

I talked to Clasko in chapter 1 and 2. I also have access to the ranch, but i can¨t figure out how to get into the dungeon beneath..

1. You need to send out 3 lv 1, 2, 3, 4 and 5 Chocobos to find treasure and have them all come back.
2. You need to have 4 lv 5 Chocobo Runners.
3. After you've done the above, you have to leave and come back, and then there will be a scene with Clasko.

I'm not entirely sure if send a Chocobo out to find some of the dungeons in other areas classifies as sending it out, but I think it does.
