The days are longer, providing ample daylight for sightseeing and enjoying the natural beauty of the Warmian-Masurian region.For those who appreciate comfortable weather for walking and exploring the Sanctuary of Gietrzwald and its surroundings, July and August are particularly good. The fields are green, and the local flora is in full bloom. This period is superb for couples or solo travellers looking for a peaceful retreat with good weather.If you prefer slightly fewer crowds and cooler, yet still pleasant, temperatures, late May, June, or September are excellent choices. The landscape is still beautiful, and you can enjoy the serenity of the area without the peak summer bustle.
