Hiking Soon on a Saturday? (Beijing)

Dear all,

Is there any place you'd like to go hiking around Beijing?

As our local hiking group - Internations Beijing Hiking, explore China might change into an acitivity group, it would be good if we can organize a hiking trip soon to somewhere you prefer to go. And I'd like to hear any opinions about it. So let me know^^

I'm currently travelling outside of China but would be back soon and plan something for a Saturday. So will look forward to it very much and hearing from you guys^^
