Where To Find Dive In Emerald: Locations, Requirements, and What to Expect

Pokémon Emerald's Dive move opens up entire sections of the game world that are otherwise completely inaccessible. But tracking down the HM and figuring out exactly where you can use it isn't always straightforward — especially if you're playing for the first time or returning after a long break. Here's a clear breakdown of where to find Dive, what you need before you can use it, and how the move factors into your Hoenn adventure.

What Is Dive in Pokémon Emerald?

Dive is both a battle move and a field HM (Hidden Machine) in Pokémon Emerald. Outside of battle, it allows your Pokémon to submerge underwater in designated deep-sea tiles, opening up underwater routes, hidden items, and story-critical locations. In battle, it functions as a two-turn Water-type move — the user submerges on the first turn and attacks on the second.

Unlike regular TMs (Technical Machines), HMs cannot be discarded, and the moves they teach cannot be forgotten without visiting the Move Deleter in Lilycove City. This matters for team-building decisions, which we'll come back to later.

Where To Find HM08 Dive in Pokémon Emerald

In Pokémon Emerald, Dive is HM08, and you receive it from Steven Stone in Mossdeep City. 🌊

Here's the exact sequence:

1. Reach Mossdeep City — This is on the far eastern side of the Hoenn region, accessible by surfing across open water routes.
2. Defeat the Mossdeep Gym — Tate and Liza, the twin Gym Leaders, use Psychic-type Pokémon. Beating them earns you the Mind Badge.
3. Visit Steven Stone's house — Steven's house is located in the northeast corner of Mossdeep City. After you defeat the Gym, speak to Steven and he will give you HM08 Dive.

There is no other legitimate way to obtain Dive in a standard playthrough of Emerald. It's a single, story-gated acquisition tied directly to Mossdeep Gym progress.

What You Need Before You Can Use Dive

Receiving the HM is only part of the equation. To use Dive outside of battle, you need:

• The Mind Badge from Mossdeep Gym (which you'll already have by the time you get Dive)
• A Pokémon in your party that can learn Dive

Not every Pokémon can learn Dive. It's restricted to Pokémon that are Water-type or have a compatible move pool. Common Emerald-accessible options include Tentacool, Wailmer, Sharpedo, Relicanth, and Pelipper, among others.

If none of your current party members can learn the move, you'll need to either swap in a compatible Pokémon or catch one before you can access underwater areas.

Where Can You Actually Use Dive?

Once you have the move and the badge, Dive can be used on dark water tiles — these appear as noticeably darker patches of deep ocean, distinct from regular Surf water. They're found primarily on:

• Route 124 — The main Dive corridor, leading to key underwater sections
• Route 126 — Contains underwater areas connected to the Seafloor Cavern, which is essential for the main story
• Route 128, 129, 130 — Additional Dive spots with items and rare Pokémon encounters

Seafloor Cavern is the most story-critical Dive destination. Reaching it requires surfing and diving through Route 126, and it's where the main plot involving Kyogre (or Rayquaza's resolution in Emerald) advances. You cannot complete Pokémon Emerald's primary storyline without using Dive.

Underwater — What You'll Find

Diving doesn't just open a shortcut. Underwater routes in Emerald contain:

• Wild Pokémon encounters — Including Relicanth, which is necessary for a specific in-game puzzle related to legendary Pokémon, and Chinchou in certain spots
• Hidden items — Scattered across the seafloor, often requiring the Itemfinder (Dowsing Machine) to locate all of them
• Underwater passages — Some areas connect to cave entrances only accessible from below the surface

The Relicanth Factor 🐟

One nuance worth knowing: Relicanth — found exclusively in underwater grass patches — is required for the Regi trio puzzle in Pokémon Emerald. If unlocking Regirock, Regice, and Registeel is on your to-do list, catching Relicanth underwater is a mandatory step.

This also means the order in which you pursue optional content matters. Diving early (immediately after Mossdeep) gives you access to Relicanth before it becomes urgent later in the game.

Teaching Dive Without Disrupting Your Main Team

A practical consideration many players run into: HMs occupy moveslots permanently until the Move Deleter removes them. If you teach Dive to a core battle Pokémon, you may find yourself losing a valuable attack slot.

A common approach is to maintain a dedicated HM Pokémon — a Water-type party member used primarily for field moves like Surf, Waterfall, and Dive — that doesn't need an optimized competitive moveset. What makes sense for your party depends heavily on which Pokémon you're already using and how far into the game you are when you reach Mossdeep.

The relationship between your current roster, your team-building goals, and how you want to handle HM coverage is ultimately the variable that shapes how disruptive — or seamless — adding Dive to your playthrough turns out to be.
