California's vast geography results in diverse climates. Coastal regions, with their mild, Mediterranean climate, offer year-round hiking opportunities, though winter rains may muddy trails. In contrast, the inland valleys and desert regions are best hiked from October to April, as summer temperatures can be prohibitive.
The Sierra Nevada, famous for its mountains and forests, is popular in summer and fall. However, winter brings heavy snowfall, making trails inaccessible. Meanwhile, the pleasant climate of Southern California allows for hiking throughout the year, with cooler, wet winters and hot, dry summers.
To summarize, California's diverse climate offers year-round hiking opportunities, varying by region. Visit
