One great place was right next to the resort. It had a lovely deep pool on the Tarra River for dogs to swim, and a rocky waterfall where humans could sit with their feet in the water. However, one kilometre down the road was a spot I liked even better, and Penny adored - also on the Tarra.
We also drove about thirty kilometres to Port Albert, where there is a calm bay (no waves at all on the two occasions Penny swam there) and a lovely walk along the shore. The dogs jumped into the water beside the path at one stage and cooled off among the mangroves, but in general we just walked along the path.
