Kailua (Kailua Village) is a small town in the Kona area, close to the sea, it is a very good place to visit. On the embankment on the harbor, tourists are in a daze with the sea breeze, and locals stand on the shore to throw poles and fish. Everything is so relaxed and casual. This is what life should have been like. The town is full of people, and there are open-top classic cars passing by. Kona is the hall of the triathlon. Each year, dozens of countries on seven continents hold separate station events, and only if they win the station rankings, they have the opportunity to travel to Hawaii to participate in the Kona Triathlon World Championships, which is open to about 2,000 participants worldwide every year. So many people think that only completing the world championships in Hawaii's Kona is a real Iron Man. The shops and cafes on the street are popular with tourists, and they spend two hours wandering around. Passing by a small shop, the ice cream sold in the order is very delicious, remember to choose the coffee taste. There is no sense of oppression in the big city, there is only a slight tide of air and a free life.
