Mikołajki is the most charming town on the Mazurian Lakes: a small settlement on a narrow strait between two large lakes, its old town preserved from the German period, and its quay so packed with sailboats in summer that the masts create a forest above the waterfront. It is the social heart of Mazurian sailing — the place where boats from across the lake system converge for the weekend, and the bars and restaurants along the water fill accordingly.
The town's architecture is a mix of Prussian brick and postwar Polish buildings, with the older German houses concentrated near the market square. There are good kayak and boat hire facilities and a small beach. The town is small enough to walk across in fifteen minutes but lively enough to feel like a proper destination. In August it becomes genuinely crowded; come in June or September for a calmer version of the same experience.
