Mushroom Fields coastline, giant mushrooms and a Trial Chamber beneath mycelium are verified destinations in this Java 26.2 seed. Spawn is (256, 72, 896). The mushroom-biome waypoint is about 317 blocks northwest of spawn; the chamber is farther north under the island.

Use seed 5109333777251974897 in Java 26.2 with normal world generation and structures enabled. Distances are measured in a straight line from spawn, and structure coordinates point to the structure, so look around for the entrance when you arrive.
The Mushroom Fields island area
Mushroom Fields are a short northwest trip from spawn. This waypoint reaches water at Y=62, while the mycelium coastline block below gives you a nearby land marker. The pictured open chasm has not been located, so plan your own descent to the chamber. Coordinates: (32, 62, 672). 317 blocks from spawn.
The mycelium coastline
Mycelium beside sea-level water marks a coastal terrace on the mushroom landscape. Use this block as a shore marker when approaching the island. Coordinates: (32, 66, 671). 318 blocks from spawn.
The giant red mushroom
A giant red mushroom gives you a distinct feature to find near the southern island area. This marker is a red mushroom block, useful for scouting the coast. Coordinates: (146, 66, 652). 268 blocks from spawn.
The giant brown mushroom
A giant brown mushroom stands east and north of the red-mushroom marker. Visit both surface features before heading farther north toward the chamber area. Coordinates: (187, 78, 628). 277 blocks from spawn.

The deep dripstone cave point
Pointed dripstone gives you a deep cave destination at Y=-51 near the chamber area. A connection from the pictured surface chasm to this block has not been confirmed. Coordinates: (185, -51, 77). 822 blocks from spawn.
The Trial Chamber under mycelium
A Trial Chamber gives you an underground destination at Y=-35 beneath the mushroom island. Directly above it, mycelium at (160, 71, 80) confirms the Mushroom Fields surface. This is not the closest chamber location to spawn. Plan a controlled descent; the pictured chasm has not been confirmed as an entrance. Coordinates: (160, -35, 80). 822 blocks from spawn.

Plan your route
From spawn, head northwest toward the verified coast and scout the red and brown mushroom points. Then travel mainly north across the island area toward the chamber X/Z position before planning an underground descent. The chasm image is retained, but its location and any passage from it to the chamber remain unverified; no chasm-based travel route is supplied.
For an aerial visit, switch to Creative and enable flight first. Use a command below, then descend slowly. For underground places, these commands arrive above the surface so you can plan a controlled descent.
