The best time to go to Costache Negri is during the late spring (May to June) and early autumn (September to October) months.
During these periods, the weather is pleasantly mild, with comfortable temperatures that are ideal for exploring the natural beauty of the region and engaging in outdoor activities. You'll avoid the intense heat of mid-summer and the colder, sometimes unpredictable weather of winter.
For those who enjoy outdoor activities like hiking or birdwatching, May and June offer lush greenery and active wildlife. The days are long, allowing for extended exploration of the surrounding countryside and the nearby Prut River.
September and October are great for travellers who appreciate cooler temperatures and the beauty of autumn foliage.
