What titles can you come up with where children travel to another world through a particular means?

Can you name who went where and how did they do it in what book?

For example:
Dorothy went to Oz via a twister carrying her in The Wonderful Wizard of Oz
The Pevensie Siblings went to Narnia through a wardrobe in The Lion, the Witch, and the Wardrobe
Wendy, John, and Michael are flown to Neverland by Peter Pan in Peter Pan
Alice went to Wonderland through a rabbit hole and to the Looking-glass world through a mirror in Alice's Adventures in Wonderland & Through the Looking-Glass
Milo drives to the Kingdom of Wisdom through the Phantom Tollbooth in The Phantom Tollbooth

TIA

Harry went through the barrier at Platform 9-3/4 in King's Cross Station / alternatively, he also went through the Leaky Cauldron -- to reach the wizarding world in Harry Potter and the Sorcerer's Stone

Karou went to Eretz via Brimstone's shop in Daughter of Smoke & Bone

Lex first reached Croak on the back of her uncle's motorcycle.

September was carried by the wind to Fairyland in The Girl Who Circumnavigated Fairyland in a Ship of Her Own Making

Thomas Hunter was transported through his dreams to an alternate reality in The Complete Circle Series by Ted Dekker.

(he's not a child, hope that's alright!)

A board game is the portal to 'another place and reality' in Jumanji by Chris Van Allsburg in the 1981 classic. It would be retold in the 1995 movie of the same name starring Robin Williams.

The Mist is the way children get to the land of the alternate Peter Pan in The Child Thief by Brom. This is a very dark and deeply flawed retelling or alternative to the Peter Pan that most know.

Cole Randolph and all of his friends were transported to the Outskirts - in book one by going through a haunted house in Sky Raiders by Brandon Mull. Jason Walker was transported to Lyrian through the mouth of a hippo in A World Without Heroes also by Brandon Mull. Andy Smithson goes to Oomaldee while washing dishes in Blast of the Dragon's Fury by LRW Lee.
