Pental Island is an inland island bound by the Murray River and the anabranch Little Murray River. Little Murray River is on the southern side of the island, with the New South Wales and Victoria border along the Murray River on the north side, making Pental Island part of Victoria.
An anabranch is when a river branches and then later both flow back into the same river. Little Murray River, sometimes referred to as Marraboor River, splits from the Murray River east of Fish Point.
The Little Murray River flows northwest and rejoins with the Murray River at Swan Hill after 46kms. Along the way, the Loddon River joins Little Murray River, and it has been argued Little Murray River is a continuation of Loddon River.
The Aboriginal people from the area called the river Parnimilli, which means little river. That’s four different names for the same river (Little Murray, Marraboor, Loddon, and Parnimilli), but Little Murray River seems to be used the most often.
Pental Island is predominately farmland and is accessed from one of two bridges, both across the Little Murray River, with no crossings from New South Wales. The crossing at Swan Hill is at the southern end of the town on Pental Island Rd. The other crossing is nearly 8km along Fish Point Rd from Murray Valley Hwy, which is 3km south-east of Lake Boga.
There doesn’t really seem there is much to do on Pental Island, other than go to Loddon Floodway 
where there is a free camp on the Murray River, and there is a spot along the river about 4kms from the bridge at Swan Hill where you can access the banks of the Little Murray River, or visit the caravan park on the island.
