Great Journey vacation
From Halopedia, the Halo wiki
The Great Journey Vacation is similar to the Delta Halo Vacation. It allows the player to walk all over and around the Control Room island and in the water surrounding the island.
How to Get There
Before you go into the control chamber, you must fly down and hijack a wraith tank. Then drive it over through the water and to the sides of the mountain, it is a little hard to climb but not with the use of a few boosts!
What to do
Without a wraith, you can go on the right side and back of the mountain, but with a wraith you can explore the whole thing, and go the the top to get a great view.
