Quick answer: A river valley seed puts a river within ~256 blocks of spawn with high ground — Y 110 or above — within ~512. This finder searches for both; verified seeds for Java 26.3 and Large Biomes are listed below, each with how far the river is and a one-click map.
| Criteria | A river within ~256 blocks of spawn and ground at Y 110 or higher within ~512 blocks |
|---|---|
| Editions | Java and Large Biomes — measured Bedrock river accuracy is below our publishing bar |
| Versions | Java 26.3 |
| Verified seeds ready | 12 per edition (Java and Large Biomes, listed above) |
This page loads the finder pre-set to a river within ~256 blocks of spawn and high ground within ~512. The seeds below already match — copy one and open it on the map, or press Search for a fresh batch.
A river gives you water, clay, sugar cane and a boat route from the first day, and the high ground beside it gives you a view and a safe place to build.
Every result states how far the river is from spawn, in blocks, and marks it on the map. You can change the distance in the Terrain group.
Not yet — river search is Java and Large Biomes only. We measured Bedrock river accuracy and it came in below the bar we publish, so we do not offer it rather than ship a figure we do not trust.
