As Starlight Strand is one of the earlier unlockable areas, you can do so right from Rainbow Fields provided you know where to look and have some vegetables to spare. This Slime Rancher 2 guide tells you how.
How to Get to Starlight Strand
You’ll need 30 vegetables to feed the Cotton Gordo blocking your path to Starlight Strand. Those will likely be Carrots, but if you can get your hands on the Cotton Gordo’s favorite food, Water Lettuce, you’ll only need 15 to unlock the area.
Head to the spot indicated on the map below:
Some Water Lettuce can be found down the ramp and to the left from where the Cotton Gordo sits. Feed it the vegetables you brought with you, and once it’s had its fill, it will explode into several Cotton Slimes and grant passage into the cave it was covering.
Head down into the cave and interact with the switch. After the light spectacle, backtrack down to the spot marked on the map below:
Go through the cave and follow the path; where you need to go is obvious thanks to the beacon of light. Though you may want to make a hard right and head up a nearby path to get the second map for the Rainbow Fields area.
Head through the teleporting beacon, and you’ll find yourself in Starlight Strand.
Getting to Starlight Strand luckily doesn’t require a jetpack or anything but vegetables, though the same can’t be said for other areas. If you haven’t made your way to Ember Valley, check out our guide on that, and look for more Slime Rancher 2 guides here on GameSkinny.
