With the sand below being quicksand, missing a jump can be perilous. Heading back down, enter the ruins and go right until you reach a narrow path where Bullet Bills are being shot out, and a moving platform lies beyond that can take you further. Off to the left, there’s a little robot Binoculars you can capture to get a birds-eye view of the area, including the tower, the giant inverted pyramid beyond, and a large island to the left surrounded by a chasm.
Note that there are several easy Power Moons to grab as you head through Tostarena Town, which include: There’s some more to explore in the town, but a lot of it is frozen over, so head to the other side and down the path to the ruins.
Heading through the town, be sure to talk to the residents, and check out the Crazy Cap store - they sell items for both Coins and Sand Kingdom Purple Coins (some of which are to the right of the town entrance and others on an umbrella outside the store - and even more on the roof of the building).
