Archford

Archford is a tropical, overgrown plant region in PMU 7. One must use HM Surf from the Exbel Penninsula and beat Crescent Islet (excluding its depths) near the South Outpost Island to access it.

As it's the last region that can be unlocked, it is considered the overall hardest of the four available regions, with many late-game dungeons. Unlike other regions, Archford has its main island along with two other separate islands.

You can fly to Archford from southwest of the sky.

The main island has 11 dungeons. Archford has 17 dungeons overall.

Greenport Town
Greenport Town is the main town in Archford.

Southeastern Village
The Southeastern Village is, as the name suggests, a village on a small island southeast of Archford.

Southwestern Isle
The Southwestern Isle is a big island southeast of Archford.

Underwater
In Archford, using any of the dive spots in its sea will take you to its unique underwater subworld. Wild Water-types accompany it, and you can return back to a given dive spot by stepping on any of the landing tiles via first using Dive. Its main purpose is to hold the entrance to Seafloor Ruins.

The dive spot near Mt. Moon leads to a separate underwater map that connects to Crescent Islet's dive spot.

Abandoned Bunker
The Abandoned Bunker is an area found when entering an underground staircase located southeast on the main island, close to the Southeastern Island. The Abandoned Bunker serves no purpose beyond being a hidden place for players to wound up in.

Mudkipz Party
The Mudkipz party is an easter egg joke area ("so i herd u leik mudkipz!!11!!1" being the map name) found south of Archford, near a Mudkip doll.
