The longer daylight hours also allow for extended time exploring the surrounding trails and enjoying nature. This is an excellent time for families looking for a relaxing lakeside vacation with plenty of opportunities for outdoor fun.Early autumn, specifically September, also offers a wonderful experience with cooler temperatures and fewer crowds. The fall foliage around the lake provides a beautiful backdrop for hiking and photography.
