Spring (April‑June) – The surrounding hills burst into wildflowers, and the water level is typically high, creating mirror‑like reflections. Ideal for photography and picnics.
Autumn (September‑October) – Golden foliage adds a warm palette to the landscape. Temperatures are mild, making it comfortable for walking or jogging.
