Let's Vote:Caves Exploring in Stones Foreist? (Guangzhou)

Thinking about co-hosting a hiking event on May 2nd. But not sure how many people would be interested in join. I will post activity details later if there are more than 10 people interested.
Up for some adventures outside of the big city?
Yingxi Fenglin, 2 hours and a half from GZ. A valley surrounded by mountains , karst landforms, natural landscape like Guilin. A nice trail explored by native hikers. You get to hike outside of the city among Rice Fields and actually go into the biggest caves in South China to explore.
Date: May 2nd, Fee: 129rmb/person.
Leave at 7:45am , Come back to GZ at 20:00.
Leave comments if you are interested.
