The Grand Line cuts across the ocean and is enclosed on either side by the Calm Belts. The Red Line forms another major barrier along its course 225.
Reverse Mountain carries ships into the Grand Line on an uphill current; ships descending the other side reach Twin Cape 414 571.
Weather and currents can change abruptly. Voyagers encounter storms, hail, reversing currents, reefs, and Sea Kings; navigation also requires accounting for the route indicated by a Log Pose 414 568.
The New World is more hazardous than the first half: its weather, currents, magnetic fields, and routes are less predictable 136 573.

Location or route	Significance
Twin Cape	First stop after Reverse Mountain; Laboon waits there for a crew that promised to return 571.
Jaya Island and the sky current	Jaya is associated with black markets, underground intelligence, and rumored routes to the sky. An upward-flowing current carries the Oro Jackson to the White Sea 187.
Sabaody Archipelago	Ships can be coated here for the descent toward Fish-Man Island, 10,000 meters beneath the sea 572.
Fish-Man Island	A passage on the way to the New World; the Going Merry emerges into New World waters after traveling through it 572 573.
Laugh Tale	The final island reached by the Roger Pirates, completing their Grand Line voyage 207 208.

The Roger Pirates complete a voyage to the Grand Line’s end, an achievement that brings Roger the title Pirate King 208.
Rock promotes Adventure Groups as a way to explore and travel without becoming pirates. Their growth reduces new pirate recruitment, while Marine pressure pushes pirate activity increasingly toward the New World 225 342 420.
The Sunshine Adventure Group enters through Reverse Mountain, takes rescue and exploration missions in the first half, and later crosses into the New World 571 572 573.
