This is a group for the more frequent hikers (defined as 10+ hikers) in Eye Opener HK Hiking to organize and participate in such activities as overseas travel, dinner, lunch and other social activities. Of course for the sake of courtesy you need to have a clear, solo, and forward facing profile picture.
As for money matters, the principle is nobody should make profit from organizing or attending events. Costs should be equally shared by event participants and surplus should go to charity. Details should be disclosed in the event description.
The event host/s can decide whether guests are allowed and make it clear in the event description.
