How to complete the Sahasra Slope Skyview Tower?

Reaching the Tower Location

  • The tower is located in West Necluda at coordinates (1344, -1170, 0166), southeast of Hyrule Field.
  • It sits on a hill overlooking Nabi Lake, making it easy to spot as you explore the region.

Talking to Bilson outside the tower

  • Bilson is the NPC guarding the tower door; he won’t let you in until you get him a mushroom from the cave directly west of the tower.
  • The cave entrance is marked on your map after you speak with him.

Finding the mushroom cave

  • Head west from the tower down the slope; the cave entrance is just below the tower.
  • Inside, you may encounter Bubbulfrogs and several common mushrooms (Hylian Shroom, etc.). No special variety is needed–any mushroom works.

Returning the mushroom to Bilson

  • Collect any mushroom and bring it back to Bilson. He will take it and open the tower door.
  • After he opens the door, you can enter the tower and use the terminal to unlock the map region.
The paradox

Some players report that the mushroom fetch is a red herring – they entered from the cave below using Ascend and opened the door from inside. If you’re stuck, try the cave-first route: break rocks with a fused weapon, stay right, then Ascend up into the tower.

The implication: this tower teaches two core Tears of the Kingdom lessons–talk to NPCs and explore every cave. Either path works, but the official solution is the simpler mushroom trade.

How do you get Bilson to open the door?

Where to find Bilson

Bilson stands directly in front of the Sahasra Slope Tower door, at the coordinates above. He’s impossible to miss–the only NPC near the tower.

What Bilson asks for

  • He asks for “a mushroom from a cave” specifically the cave to the west.
  • He won’t accept a mushroom you already have–you must pick one from that cave.

Fetching the correct item

  • Enter the cave, pick any mushroom (Hylian Shroom, Stambulb, etc.), and return to Bilson. He’ll take it and open the door.
  • No need to defeat enemies; the cave is safe and quick.
The catch

If you collect a mushroom before talking to Bilson, he still won’t open the door. You must trigger his dialogue first, then pick a fresh mushroom from the designated cave.

What this means: the game forces you to listen to NPC instructions and follow a specific path–a classic open-world tutorial disguised as a fetch quest.

What is special about the Sahasra Slope Skyview Tower?

Map reveal functionality

Activating this tower reveals the entire West Necluda region on both your surface map and sky map, including the coordinates of nearby sky islands.

Tower design and location

  • It sits on a sloping hill, hence the name “Sahasra Slope.” The tower’s base is elevated, and the door faces the slope.
  • The surrounding area includes Nabi Lake to the north and several caves and korok puzzles.

Relation to other Skyview Towers

  • One of 15 Skyview Towers in Tears of the Kingdom.
  • Unlike towers that require combat or complex traversal, Sahasra Slope’s puzzle is unique: a simple NPC interaction with no enemies required.
Why this matters

This tower sets expectations that puzzles can be solved through conversation and exploration, making it a perfect introduction for players unfamiliar with Skyview Tower mechanics.

The pattern: Sahasra Slope trades combat for conversation–a gentle onboarding that rewards paying attention to dialogue.

Where is the mushroom cave for Sahasra Slope Skyview Tower?

Cave entrance coordinates

The cave entrance is directly west of the tower, about 30 meters down the slope. After you talk to Bilson, a marker appears on your map.

Enemies inside the cave

  • You’ll find Bubbulfrogs hanging from the ceiling. They’re harmless but drop Bubbul Gems when defeated.
  • No aggressive enemies–the cave is safe even early in the game.

Items besides mushrooms

  • Common mushrooms (Hylian Shroom, Stambulb, Brightcap).
  • Brightcaps are especially useful for lighting up dark areas.
  • Some ore deposits and a chest may contain arrows or rupees.
Bottom line: Even if you don’t need the mushroom for Bilson, the cave is worth stopping by for Bubbul Gems and Brightcaps.

The trade-off: the cave is small and quick–perfect for a beginner area, but seasoned players may skip it after the first visit.

Is it worth going up the Sky Tower?

What the tower unlocks

  • Unlocks fast travel point and complete map of West Necluda, including sky islands.
  • Reveals nearby shrines and points of interest.

Time investment vs. reward

  • Total unlock time: about 5 minutes, including the mushroom fetch.
  • Reward: permanent fast travel, exploration access, and progression toward 100% completion.

Comparison with other towers

  • This is one of the least demanding towers. Others (e.g., Lindor’s Brow, Pikida Stonegrove) require temperature gear or long climbs.
  • For players early in the game, this tower provides a huge map unlock with minimal effort.
The upshot

If you’re aiming for 100% completion, every tower is mandatory. But as a casual player, Sahasra Slope offers the best payoff-per-minute ratio of any tower in the game.

For the time-starved player, the choice is clear: spend five minutes on this tower and get a massive region reveal, or skip it and miss out on a key fast travel point.

– Reddit user

The Sahasra Slope Skyview Tower may be the friendliest puzzle in Tears of the Kingdom. It rewards the most basic open-world instincts: talk to the person, go where they point, pick up what they ask for. For the completionist, it’s a five-minute detour that unlocks an entire region. For the explorer, it’s a reminder that sometimes the simplest path forward is the most rewarding.
