The picturesque Gambier (Mount Gambier) is a small town built on the volcanic site. It arrived here at sunset. Taking advantage of the sunset, I just went to visit the beautiful Blue Lake. The blue lake will turn iron gray in winter, and the sky is blue in summer. It was clear and beautiful. Get out of the car and overlook the lake with a blue color that is hard to describe in words, and perhaps the ocean heart of the Titanic is just that. After a day in the car, we started the mountaineering trip before dinner, stretching our waists and breathing the sweet Gambler wind in the evening, and returning to the hotel we stayed tonight until the sunset was completely gone, and the parking lot in the yard was full of a large number of Harley motorcycles. Nearly 20 drivers, aged around 50, were drinking beer and chatting on motorcycles, and later learned that they were travelers driving from Melbourne on the Great Ocean Road, and Dad couldn't help but lament that people were really smart.
