Key takeawaysSpoilers

Use this page as a preparation and navigation reference for the deepest endgame section of the Depths.

  • Expect extreme underground hazards The deepest areas are among the darkest and most treacherous parts of the Depths. Bring tools and supplies that make dark, Gloom-heavy exploration manageable before pushing farther below Hyrule Castle.
  • The area is tied to the finale The region functions as a critical endgame location where Link faces the game’s final threats. Treat the descent as a major spoiler point rather than a routine expedition.
  • Investigation leads here from several directions Josha and Robbie’s Depths investigations, as well as Master Kohga’s Yiga Clan missions, help direct attention toward the underground regions connected with the castle.
  • Exploration can produce valuable equipment Pristine weapons may appear in deep zones, but some valuable finds are guarded by formidable enemies such as Gleeoks. Decide whether the reward is worth the risk before engaging.

The Deepest Depths overviewSpoilers

The Deepest Depths is an endgame quest setting focused on the lowest and most dangerous subterranean regions beneath Hyrule Castle.

The name refers to the lowest reaches of the Depths in The Legend of Zelda: Tears of the Kingdom, particularly the vast underground area beneath Hyrule Castle. These zones are darker and more hazardous than many other parts of the Depths, making preparation for limited visibility and Gloom especially important. The area is not simply another underground route: it is tied directly to the final stage of Link’s pursuit of Ganondorf and the threats hidden below Hyrule.

Exploration of this region connects several strands of the Depths storyline. Josha and Robbie encourage Link to investigate the underground world, while Master Kohga and the Yiga Clan provide another route into the broader conflict beneath Hyrule. Their investigations help establish why the Depths matter, but the deepest area ultimately serves a more immediate purpose: guiding Link toward the confrontation far below Hyrule Castle.

The descent is a major turning point because the environment itself becomes part of the challenge. Gloom makes careless exploration dangerous, darkness can obscure routes and enemies, and formidable threats may guard valuable equipment. Pristine weapons can be found in deep regions, sometimes near powerful enemies such as Gleeoks, so exploration can be rewarding but should not be confused with a safe detour.

The deepest reaches are associated with the game’s final threats and Ganondorf’s lair. Entering this region therefore carries major story implications, and players who want to complete optional exploration or prepare equipment should consider doing so before committing to the final approach. The exact route, combat encounters, and available resources can vary according to how much of the Depths the player has already explored.

Requirements and preparation

The deepest areas require practical preparation rather than a published numerical level requirement.

  • RequiredAccess to the DepthsYou must be able to enter and travel through Hyrule’s underground region before reaching the areas beneath Hyrule Castle.
  • RecommendedGloom preparationGloom is a persistent hazard in the Depths, and the deepest reaches are particularly dangerous. Carry healing or other supplies suited to recovering from Gloom exposure.
  • RecommendedReliable light sourceDarkness is a defining hazard of the area. Brightbloom Seeds or another dependable way to illuminate the route makes navigation and enemy detection safer.
  • RecommendedCombat readinessThe endgame route leads toward Ganondorf and may pass through formidable enemies. Upgrade equipment and carry a versatile set of weapons before beginning the descent.
  • OptionalOptional exploration suppliesIf you intend to search for pristine weapons or challenge powerful guardians such as Gleeoks, bring enough resources to support a longer expedition.

WalkthroughSpoilers

  1. 01

    Prepare for the endgame descent

    Finish optional preparation before descending

    Before committing to the deepest route, complete any desired surface or Depths exploration and organize healing, light, and combat supplies. The area is tied to the game’s final threats, so returning to prepare later may be less convenient than preparing first.

    Location: Hyrule and the Depths

    TipUse the opportunity to improve your equipment and stock supplies for Gloom-heavy exploration.

  2. 02

    Begin the underground approach

    Enter the Depths and establish a safe route

    Travel through the Depths while keeping the route illuminated and watching for Gloom-covered ground. The deepest sections are among the darkest and most treacherous parts of the map, so avoid rushing into unlit areas where hazards and enemies are difficult to read.

    Location: Depths

    Watch outAllowing Gloom to accumulate while far from a safe route can leave Link vulnerable before the main confrontation.

  3. 03

    Navigate toward the castle’s underground region

    Use landmarks to maintain your bearings

    The underground terrain can make direction difficult to judge, particularly when darkness hides walls, drops, and branching passages. Mark useful discoveries and keep track of the route toward the area beneath Hyrule Castle rather than wandering into unrelated parts of the Depths.

    Location: Deepest areas of the Depths

    TipLight the area ahead before crossing unfamiliar ground so that drops and enemy silhouettes become visible.

  4. 04

    Optional: search for pristine weapons

    Decide whether to detour for equipment

    Deep zones can contain pristine weapons, but the source material notes that formidable enemies such as Gleeoks may guard valuable finds. Take the detour only if your resources and equipment support the fight; otherwise, record the location and continue toward the endgame route.

    Location: Deep zones of the Depths

    Watch outA resource detour can consume healing and weapons needed for the approach to Ganondorf.

  5. 05

    Reach the deepest approach

    Follow the route beneath Hyrule Castle

    Continue toward the lowest subterranean area beneath Hyrule Castle. This is the point at which ordinary Depths exploration gives way to a critical endgame location, so make a final check of supplies before entering the route’s most consequential section.

    Location: Beneath Hyrule Castle

    Checkpoint
  6. 06

    Approach the final threat

    Advance toward Ganondorf’s lair

    The deepest route leads toward the lair where Ganondorf is located far below the castle grounds. Expect major story spoilers from this point onward and treat the approach as a commitment to the final threats rather than as a normal treasure run.

    Location: Far below Hyrule Castle

    Watch outThe exact encounter sequence and checkpoint behavior are not specified in the supplied source material.

  7. 07

    Complete the endgame confrontation

    Confront the final threats

    At the end of the descent, Link faces the game’s final threats in the underground region. Use the preparation made before entering the Depths, and do not assume that optional exploration rewards are more important than preserving resources for the conclusion.

    Location: Ganondorf’s underground lair

Mission mechanics

The defining mechanic of this section is environmental pressure. The Depths are generally affected by Gloom, while the deepest areas add severe darkness and difficult terrain. Exploration is therefore a resource-management exercise: illuminate the route, avoid unnecessary exposure, and keep enough healing and equipment available for the journey below Hyrule Castle.

The area also rewards risk-taking. Pristine weapons can appear in the deep zones, but some are associated with formidable enemies such as Gleeoks. This creates a choice between taking a detour for better equipment and conserving resources for the final approach. The safest answer depends on Link’s current equipment and preparation, not on a fixed recommended route.

Movement abilities can help with traversal, and players have used advanced techniques such as Recall Launch to travel from the depths toward high sky islands. That technique is an optional traversal possibility rather than a required objective of The Deepest Depths, and the supplied material does not establish a specific launch point or mandatory puzzle.

What works and what does not

Strengths

  • The descent gives the Depths a strong endgame purpose rather than treating the underground map as a disconnected optional region.
  • Darkness and Gloom make route planning and resource management meaningful.
  • Exploration can lead to valuable pristine weapons and other rewards.
  • The location ties together investigations involving Josha, Robbie, and Master Kohga.

Weaknesses

  • Darkness can make navigation difficult when the player has not prepared a reliable light source.
  • Gloom increases the cost of careless exploration and can make detours risky.
  • Powerful enemies, including Gleeoks, may guard valuable finds.
  • The supplied material does not document a fixed step-by-step route, encounter count, or guaranteed drop table.

Best uses

  • Treat the area as an endgame preparation check and final approach.
  • Use optional detours to improve equipment only when enough resources remain for the main confrontation.
  • Follow the investigative thread through the Depths to understand why the underground route matters.

AftermathEnding spoilers

The descent leads into the finale

The deepest reaches of the Depths are essential to the main storyline because they lead toward Ganondorf’s lair and the game’s final threats. Once the player treats the area as an endgame approach, optional resource hunts and unfinished Depths investigations become the main reasons to delay the final advance.

Trivia

  • The phrase “deepest depths” describes the lowest subterranean areas of Hyrule, particularly the region beneath Hyrule Castle.
  • Players have used advanced movement techniques such as Recall Launch to travel from the Depths toward high sky islands, although that technique is not established as a required part of this quest.
  • The area’s value is both narrative and practical: it contains the route to the final threats and can also provide access to pristine weapons.
