+### S3 Cross-Region Access
+
+S3 Cross-Region bucket access can be turned on by setting catalog property `s3.cross-region-access-enabled` to `true`. 
+This is turned off by default to avoid first S3 API call increased latency.
+
+For example, to enable S3 Cross-Region bucket access with Spark 3.3, you can start the Spark SQL shell with:
+```
+spark-sql --conf spark.sql.catalog.my_catalog=org.apache.iceberg.spark.SparkCatalog \
+    --conf spark.sql.catalog.my_catalog.warehouse=s3://my-bucket2/my/key/prefix \
+    --conf spark.sql.catalog.my_catalog.type=glue \
+    --conf spark.sql.catalog.my_catalog.io-impl=org.apache.iceberg.aws.s3.S3FileIO \
+    --conf spark.sql.catalog.my_catalog.s3.cross-region-access-enabled=true
+```
+
+For more details, please refer to [Cross-Region access for Amazon S3](https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/s3-cross-region.html).
+
 ### S3 Acceleration
 
 [S3 Acceleration](https://aws.amazon.com/s3/transfer-acceleration/) can be used to speed up transfers to and from Amazon S3 by as much as 50-500% for long-distance transfer of larger objects.
