How To Access
At the time of writing this, the Coral Island wiki says you need to complete the Rare Altar unlock the Savannah, but that is not true. I've also seen claims of needing to be Rank A, but that is also not true.
It is unlocked by completing 18 offerings at the Lake Temple. I unlocked it for myself at Rank B with that many offerings and have confirmed with others that they only needed 18 offerings.
After you get the cutscene of the bridge being rebuilt, you can follow the path to the right of Paul's house up the mountain and across the bridge. There will be a teleport spot and a large flower there, and interacting with that flower will take you to the Savannah.
Map
This is a general layout map of the Savannah area. I was seeing comments from people that disliked the lack of map or were having trouble navigating it, so I hope this can help.
Entrance : This flower is the only way in and out without using a warp sesajen. There is no fast travel spots in the Savannah region.
Cave of Memories : The cave section of the Savannah. You cannot access this without reaching Rank B and progressing the Giant's questline. You'll have a dream one night of the vines blocking the cave being removed when your rank is high enough. For the Giants, once you've freed all the Giants in the Coral Island cave, you'll get a new quest telling you to Go to the Savannah which is followed by a quest telling you to go to the Cave of Memories and it will be unlocked from there.
The cave is different from the previous cave:
Each checkpoint is now set 25 floors apart so you need to have enough time and resources to power through that distance.
There is a LOT of loot drops here. Lots of high value ones. You will be overburdened by the amount of fossils, geodes, and chests you get. There is also a regularly changing "loot of the day" system that'll be displayed upon entering the cave. Different resources, decor items, giant crops, etc. These items will drop regularly. Sometimes you'll get lucky and the drop will be something like dynamite that'll make clearing the floors easier.
You will need your axe. Some floors have stumps, logs, and mushroom trees instead of rocks for you to clear.
Ranch : You can buy the new animals (Ostrich and Buffalo) here. You cannot purchase anything at the Savannah Ranch until after you've done the mural altar (unlocked at Town Rank A).
Treasure Bubbles : Loot boxes. You submit crops to it until you've reached 1000 points and it will dispense a random item reward. I've only seen decor items unique to the Savannah from this and haven't seen comment of anything else from it. These items are also sometimes part of the loot of the day drops in the Cave of Memories so I do not believe you need to rely on the Treasure Bubbles' RNG to get them. There are two of them in the Savannah, one to the far west and one to the far east.
