How the PEAK Daily Map Works: Reset Time, Rotation and Biomes

When the island changes

The island rotates once every 24 hours, at 17:00 UTC. The window you are playing in is named after the day it started on in UTC, which is why players in Asia see the “new” island in the early hours of their next morning.

Daylight saving shifts these by an hour in winter; the UTC time does not move. The countdown on PEAK map today always shows the time left in your own time zone.

Every expedition climbs the same six regions in the same order. Only regions two to five change from day to day:

1. Shore: always first.
2. Tropics or Roots.
3. Alpine or Mesa.
4. Caldera or Gloom.
5. The Kiln (always after the Caldera) or The Citadel (always after the Gloom).
6. The Peak: always last.

That gives eight possible lineups. In the current pool, all eight appear:

Tropics and Roots each show up on 104 days; Alpine on 105 and Mesa on 103; Caldera and Gloom each on 104. Over a full cycle the choices are essentially even. The biome rotation page lists today’s lineup and the next week.

The 208-day cycle

The developers generate island batches themselves and add them to the game for the daily rotation, rather than generating a new island on the fly each day. The current pool has 208 islands, and they play in a fixed order. A given island therefore comes back 208 days later, with the same terrain, the same luggage spots and the same Tomb status.

Two things can break the cycle:

• A patch swaps the pool. Patch 2.6.a (2 October 2026) replaced the previous 21-island batch because it was “weirdly consistent” in its biome choices. Patch 3.0.0 (October 2026) replaced that batch again, and grew the pool from 21 islands to 208. The order kept going, but each slot now holds a different island.
• A pool grows or shrinks. If the developers add more islands, the cycle length changes with it.

When either happens, this site re-captures the new islands from the game itself; a daily check of the game’s Steam build flags the patch, and the map is usually updated within a day or two.

The pool in numbers

Across the current 208 islands, a typical day holds:

Some markers are biome-specific: belltowers (7) and early worms (20) in the Gloom, beehives (1–5) in the Tropics, antlions (1 or 2) on every Mesa day, and mimic luggage in the Citadel on 71 of 208 days. The Tomb is open on every Mesa day in this pool (103 of 103).

What stays the same and what changes

This is what makes a daily map useful: once you know where today’s ancient and clown luggage sit, the knowledge holds for every attempt until the next reset.

How to use the daily map

• Plan the luggage route. The luggage locations page groups every box by biome, so you can decide which detours are worth it before you leave the Shore.
• Check the Tomb on Mesa days. In the current pool it is open on every Mesa day, and the Ancient Idol inside is the only way to earn the 24 Karat badge. See today’s Tomb status.
• Badge hunting. Days with three or more clown luggage make the Jester badge much easier, and Gloom days are the only ones with belltowers for Bellringer.
• Retry the same island. Because the island does not change until 17:00 UTC, a failed run is a free scouting trip for the next attempt.

Reading the front and side views

The front view looks up the mountain: a marker’s height on the image is roughly how far up the climb it sits. The side view shows the same markers from an angle, revealing depth, such as a box inside an Alpine cave. Only the Shore and regions two and three have one.

Tools on the full-screen map

Tap a marker to pin it, then:

• Mark found greys it out; progress is saved in your browser per map day.
• Copy link copies a URL that opens the map on that exact marker.

Filters hide whole layers (luggage, belltowers, critters, amulets, tombs) or single types, and the map-day picker browses other days in the current data, including upcoming islands.

The /today/ pages

Each today page covers one marker type or biome: a mini-map, a total (front view only, so nothing counts twice) and a table whose rows open that spot on the map. Biome pages such as today’s Alpine also say whether the biome is on today’s island and, if not, preview its next appearance.

Worked example

The 8 October 2026 island ran Tropics, Mesa, Gloom and the Citadel, with the Tomb open. A badge-hunting plan:

1. Tropics: three beehives for Honeycomb.
2. Mesa: the Tomb first, then the oasis capybaras (Yellow Winterberry) and some of its three clown luggage.
3. Gloom: ring some of the 7 belltowers for Bellringer.
4. Citadel: three more clown luggage, so Jester (two in one run) is easy.

That 8 October island was from the previous pool, which had no Mesa statue. In the current 208-island pool the Mesa has one too, so a scout lost there can revive at the Mesa statue.
