Sahasra Slope Skyview Tower Guide: Unlock & Cave

You’re standing at the base of a tall stone spire in West Necluda, ready to unlock the Skyview Tower—but a nervous-looking NPC named Billson won’t let you near the door. He’s not asking for a sword or a rare gem; he wants a common Hylian Shroom from the cave just downhill. What seems like a trivial errand actually opens up one of the most scenic viewing points in The Legend of Zelda: Tears of the Kingdom, revealing hidden shrines, a bubbulfrog-filled cavern, and the entire West Necluda map. This guide walks you through every step—from the mushroom fetch to the tower terminal—so you can sky-dive into the region with full intel.

Region: West Necluda ·
Tower Purpose: Reveals West Necluda surface and sky map ·
Required Item: Hylian Shroom ·
Key NPC: Billson ·
Nearby Cave: Sahasra Slope Cave

The snapshot above distills the entire unlock loop: four steps, one cave, and a single mushroom stand between you and the West Necluda map.

Eight key facts, one pattern: almost everything you need—the cave, the mushroom, and the NPC—is within a two-minute walk from the tower base. The coordination data from thespike.gg confirms that the cave entrance sits roughly 150 meters southeast, placing the entire unlock loop in a tight, beginner-friendly radius.

How to unlock Sahasra Slope Skyview Tower in Tears of the Kingdom?

Step 1: Find Billson outside the tower

• Travel to the tower at coordinates (1344, -1170, 0166) in West Necluda (thespike.gg (tier2)). Billson is standing near the entrance, blocking the door.
• He refuses to let you inside until you bring him a Hylian Shroom from the nearby cave. According to multiple video sources, his dialogue explicitly mentions the mushroom (Nintendo Life walkthrough (tier3)).

The implication: Nintendo designed this as an early-game teaching moment—forage before you climb.

Step 2: Retrieve a Hylian Shroom from Sahasra Slope Cave

• The cave entrance is just downhill from the tower, on the left as you descend (YouTube – Adam Conner guide (tier3)). Coordinates: (1473, -1258, 0125).
• Inside, you’ll find scattered Hylian Shrooms—usually one or two are enough. The cave also contains Horriblins and a Bubbulfrog (YouTube – Nintendo Life (tier3)).

What this means: the cave serves double duty—it supplies the quest item and offers a bonus enemy encounter for players willing to explore.

Step 3: Deliver the mushroom to Billson

• Return to the tower entrance and give Billson the Hylian Shroom. He will step aside and open the door.
• Some guides report that you can also bypass this step by entering the cave below, breaking rocks, and using Ascend to reach the tower interior from below (thespike.gg (tier2)). However, the intended path is the mushroom exchange.

Step 4: Activate the tower

• Once inside, interact with the terminal to register the Skyview Tower. This reveals the entire West Necluda map on both the surface and the sky layers (thespike.gg (tier2)).
• Fast travel to the tower becomes available immediately after activation.

What is special about Sahasra Slope Skyview Tower?

Scenic view of Nabi Lake and West Necluda

• The tower sits on a hill overlooking Nabi Lake, offering a panoramic vista of the region (thespike.gg (tier2)). From the top, you can spot several shrine locations.

Unlocks both surface and sky map for the region

• Unlike some towers that only expose the ground map, activating Sahasra Slope Skyview Tower fills in the sky layer as well—crucial for locating sky islands and Zonai devices (thespike.gg (tier2)).

Gateway to nearby shrines and caves

• After unlocking, you’ll see shrines such as Jochi-iu Shrine and others pop up on the map. The area is dense with foraging spots and side quests.

Why this matters: this tower is not just a fast-travel point—it’s the central hub for exploring the eastern edge of Necluda.

Where is the Sahasra Slope Cave and what does it contain?

Sahasra Slope Cave location

• Coordinates (1473, -1258, 0125), directly southeast of the tower (thespike.gg (tier2)). The entrance is a small fissure in the hillside, partially hidden by grass.

Mushrooms and bubbulfrog in the cave

• The cave holds multiple patches of Hylian Shrooms. A Bubbulfrog roams the deeper section; defeating it drops a Bubbul Gem, which can be traded for armor pieces (YouTube – Nintendo Life (tier3)).

Cave layout and tips

• Stick to the right wall after entering, breakable rocks block the path—use Bomb Flowers or a stone-fused weapon (thespike.gg (tier2)). The inner chamber is small but contains the Bubbulfrog and the Ascend exit spot.

The catch: if you’re only after the mushroom, you don’t need to break all the rocks—the Shrooms are near the entrance.

What shrines can you find near Sahasra Slope Skyview Tower?

Jochi-iu Shrine

• A puzzle-based shrine located north of the tower. After activation, its coordinates appear on your map. The challenge involves manipulating water flows.
• Source: thespike.gg map overlay shows its relative position (thespike.gg (tier2)).

Other shrines visible after tower activation

• Several other shrines in West Necluda become marked after the tower syncs, including combat and traversal trials.

The pattern: unlocking this tower is effectively the key to the entire western Necluda shrine network—skip it and you’re exploring blind.

Is it worth going up the Sky Tower?

Benefits of activating the tower

• Full map visibility for West Necluda, fast travel, and discovery of shrines, caves, and korok seeds (thespike.gg (tier2)).

What you miss if you skip it

• Without this tower, you cannot efficiently navigate the region. Key quests—including the nearby “A Forgotten Stone” quest—are hidden until the map loads.

The verdict: for any player aiming to complete Tears of the Kingdom’s sky and surface chart, this tower is not optional—it’s the spine of West Necluda exploration.

“I need a Hylian Shroom from the cave down there. Can’t let you in without one—boss’s orders.”

— Billson (in-game dialogue, as reported by Nintendo Life (tier3))

“After activating the tower, the West Necluda map fills in instantly, revealing shrines you couldn’t see before.”

— thespike.gg guide (tier2 editorial source)

For players completing their Hyrule map, the choice is simple: fetch a mushroom, unlock the tower, and gain a full view of West Necluda—or wander blind. The cave holds a bonus reward that makes the detour doubly worthwhile.
