**A Learning Center for Developing Forests: Preserving Rare Plant Species for Sustainable Planting as Inspired by Royal Initiatives** For those who wish to breathe in fresh air amidst lush green mountains, the Phu Hin Rong Kla National Park in Phitsanulok Province is the perfect destination. Here, you can also explore a learning center focused on the development of forests and the nurturing of rare plant saplings—a project that aligns with the esteemed royal initiatives. The Forest Development Project at Phu Hin Rong Kla was established for the rehabilitation of forest conditions, the cultivation of saplings, and the enhancement of the quality of life for local residents. This project also features an Arabica coffee plantation and a demonstration area for pesticide-free strawberry cultivation, allowing visitors to engage closely with these initiatives. The project area is home to six significant viewpoints with rocky cliffs, including Titanic Cliff, Love Encounter Cliff, Love Declaration Cliff, Soulmate Cliff, Unforgettable Love Cliff, and Breakup Cliff. Additionally, visitors can experience stunning trails through fields of colorful paper flowers blooming along the cliffs during the winter months. **Must-See Attractions:** - **Bumpy Stone Plain:** A natural formation of stone erosion that creates a unique bumpy landscape along the cliff edge. - **Flag Hill:** One of the most beautiful spots in Thailand to witness the sunset. While there are no designated camping areas within the project, accommodations are available at Phu Hin Rong Kla National Park, located approximately 2 km away. **Unmissable Activities:** - Stroll through the flower fields at Love Encounter Cliff and admire the changing colors of maple trees at the Military Political School during the winter. - Wander along the nature study pathway from Bumpy Stone Plain to Flag Hill and Sun Crack, spanning approximately 2,460 meters.
