Just go to the scar, it's easy with a Griffin. I'd recommend heath brews, ghille, sleeping bags and a griffin with 10k+ health and an absolute minimum of 800 stam
I usually have someone with me on another griffin or wyvern incase you get insta killed.by a poison wyvern, have them wait out side and come in to whistle follow on the other griffen if you die
I'd say bring a couple of pteras that you don't mind losing to learn the layout before bringing in a griffin. But you will most likely be killed on a ptera unless you're a pro.
Take a Griffin, get all dragons to try and attack you, fly high up then glide down as fast as possible thus leaving all the dragons high up away from the eggs. Take whatever you like and take your time
