One of the unique features of Happo-One is a phenomenon known as altitudinal inversion, where alpine plants that are typically found at higher elevations grow at lower altitudes, while species usually seen in lowland areas appear at higher elevations. Happo-One is home to as many as 347 species of alpine plants, including several endemic species that carry the name "Happo" in either their scientific or common names.

As you climb, the temperature drops by about 0.6 °C every 100 meters, and wind can lower the perceived temperature by 1 °C for every 1 m/s. Dress in layers suited for both warm and cold conditions. Even in summer, long-sleeved, quick-drying base layers are recommended. Hiking can be more strenuous than expected — stay hydrated and take regular water breaks.

• Accessories

  UV rays get stronger at higher elevations. Protect yourself by wearing a hat, covering up with clothing, using sunglasses and applying sunscreen. A neck gaiter or towel is also recommended to shield your neck. Don’t forget to bring rain gear in case of sudden changes in weather.

• Shoes

  Trails can be slippery and muddy, especially after rain. Comfortable athletic shoes or hiking shoes/boots are recommended for better traction and safety.

• Insect Protection

  Happo-One is home to various creatures, including insects that may bite or sting. We recommend using bug spray to protect yourself during your hike.
