Phu Lan Ka is a must-visit during the late rain and early winter season. The natural beauty is breathtaking, especially when you can see the mist in the morning. It is a refreshing experience to wake up and take a deep breath of fresh air. This destination is perfect for adventure enthusiasts and nature lovers alike. While hiking along the trail, you'll encounter the stunning blooms of the Dipterocarp trees, adding vibrant colors to your journey. In addition, there is a hiking route that follows the cliffs, allowing you to pass through various sites such as the jagged rock field and the orchid cliff. If you're short on time, don’t miss the chance to visit the "Stone Castle Forest," where large boulders await you to climb and take in the sweeping views. From this vantage point, you can clearly see the Dipterocarp forest and the rolling grassy plains cascading down the mountainside.
