Updated for Java Edition 26.3 (October 2026).
A frozen river is the river biome of snowy regions: a winding channel of water with a sheet of ice on top. It runs mostly through snowy plains and snowy taiga. In our sample of 300 Java 26.3 seeds, one was within 1,000 blocks of spawn in 34% of worlds. Follow it to reach the snowy biomes where igloos and snowy villages generate.
| Dimension | Overworld |
|---|---|
| Where it generates | In place of a normal river in cold regions, mostly through snowy plains and snowy taiga |
| How common | 0.8% of the surface in our sample (about 1 block in 120) |
| Distance from spawn | Median 1,497 blocks; within 1,000 blocks in 34% of seeds, within 2,000 in 60% (our sample) |
| Mobs | Squid, salmon, the odd drowned; glow squid in underground water; the usual hostile mobs at night |
| Notable blocks | Ice over the water, snow on the banks, patches of sand, clay and gravel on the bed, bushes. No seagrass |
| Structures | Ruined portals; trial chambers and mineshafts underground |
| Climate | Temperature 0.0, downfall 0.5 (snow, not rain) |

How to find a frozen river
Look for snow. In our sample, a frozen river’s edge touched snowy plains 38% of the time, snowy taiga 33%, regular taiga 10%, snowy beach 8% and frozen ocean 3%. If you are walking along a normal river through a spruce taiga, keep following it toward the snow and it will ice over. On open snowy plains, a frozen river is the long, flat strip of ice winding between the hills.
These three Java 26.3 seeds put a frozen river close to spawn, two of them within 100 blocks. Each coordinate is inside the river, checked at block level.
| Seed | Frozen river at | From spawn | Map |
|---|---|---|---|

X -270, Z 14 | 64 blocks | Open on the map |

X -1134, Z 254 | 500 blocks | Open on the map |
With cheats on, /locate biome minecraft:frozen_river finds the nearest one, or paste your seed into the biome finder to see every snowy biome around spawn. These are Java seeds; the same number on Bedrock gives a different world. Rivers are narrow, so zoom in on the map to see them.
Frozen river vs river
A frozen river is the same kind of channel as a normal river, in a colder climate. The ice is the obvious difference, but the mobs and plants change too:
| Feature | Frozen river | River |
|---|---|---|
| Surface | Ice over the water | Open water |
| Temperature | 0.0 (snow) | 0.5 (rain) |
| Seagrass | No | Yes |
| Squid and salmon | Both | |
| Drowned | Rarely | Much more often |
| Bushes (since 1.21.5) | Both | |
| How common (our sample) | 0.8% of the surface | 6.3% of the surface |
| Median distance from spawn (our sample) | 1,497 blocks | 76 blocks |
| Within 1,000 blocks of spawn (our sample) | 34% of seeds | 98% of seeds |
So in our sample of 300 Java 26.3 seeds, a normal river was almost always right by spawn, while a frozen river was usually more than a thousand blocks away. If you want drowned for tridents, a normal river is the better place to hunt.
Mobs in a frozen river
Can squid spawn in a frozen river?
Yes. Squid spawn in the water under the ice, and so do salmon. Glow squid can turn up in dark underground water below the river. No land animals spawn in the river itself; any you see on the ice have wandered in from the biomes around it.
Hostile mobs
At night you get the usual Overworld mobs: zombies, skeletons, spiders, creepers, endermen and the occasional witch. Drowned can spawn in the water, but in a frozen river they are rare. Strays spawn on the snowy plains around it, not in the river itself.
Using the ice
The ice is the main resource. Mine it with a Silk Touch tool to keep it; without Silk Touch the block turns into water. Nine ice blocks craft into packed ice, which doesn’t melt. A boat slides much faster on ice than on water or land, so a long frozen river makes a ready-made fast road through snowy country.
To fish, break a hole in the ice and cast into the water below; fishing works the same as anywhere else. Keep torches and other bright lights a few blocks back from the river if you want the ice to stay, because strong block light melts ice.
Structures near a frozen river
Few structures generate in the river itself: ruined portals on the surface, and trial chambers and mineshafts underground. The reason to follow one is what sits beside it. Igloos generate in snowy plains, snowy taiga and snowy slopes, and snowy villages only in snowy plains, the two biomes a frozen river most often runs through.
What changed in 2025-26
Nothing changed in frozen rivers in Wilderness Bound (Java 26.3, September 2026).
In Spring to Life (Java 1.21.5, March 2025), bushes, a new decorative block, started generating in small patches in frozen rivers (and normal rivers). The frozen river was also listed as a cold biome for the new farm animal variants: pigs, cows and chickens don’t spawn here naturally, but one spawned here (with a spawn egg, for example) comes out as the cold variant.

How we measured
The numbers on this page come from our own seed map engine, running Java Edition 26.3 world generation. We generated 300 random seeds and sampled every 16th block across a 10,240 by 10,240 block square centered on each world’s spawn. “How common” is the frozen river’s share of those samples; “distance from spawn” is how far the nearest frozen river sample was. The seeds above were picked from the same run, and each coordinate was re-checked at block level.
