Has anyone spent time at the Phong Nha Botanic Garden? I’m curious if it’s worth adding to my itinerary after cave tours. What kinds of plants and wildlife can you see there? Are there short walking trails, guided nature talks, or picnic spots? How long should I plan for a leisurely visit? Is the entrance fee reasonable compared to other attractions in the area? I’d love to see unique flora and maybe spot some butterflies or birds. Any suggestions on best times of day or nearby cafes to combine with this stop?
