The 8 checkpoints of the “Discovering Robin's Nest Country Park” Hiking Challenge are distributed along the Robin's Nest Country Trail and Lin Ma Hang Country Trail. Generally, completing all 8 checkpoints in one go takes at least 5 hours and requires adequate preparation beforehand. There are no supply points at the two entrances/exits of the Robin's Nest Country Park or along the hiking trails. There are also no alternative exit routes during the hike. Participants should assess their abilities, hike in groups, carefully read the Challenge Guide, plan a suitable route to complete the checkpoints based on their physical fitness and experience, and bring sufficient drinking water, food, and hiking equipment. Before setting out, please pay attention to the weather forecast; and once on the trail, keep an eye on the weather conditions at all times.
