Just a night at the Coquitlam Base5 climbing gym, formerly known as Coquitlam cliffhanger.

I'll be there around 6pm with my sister, climb for an hour or two. 

I can lead belay and I'd be more than happy to do some lead climbing if you can belay. But you're also welcome to show up if you never climbed before. It's $15 or so for entry and gear rental if you don't have a pass, less if you have your own gear BCMC members get 10% off. You won't be able to belay anybody until you either take their $60 course (which you have to book), or show you already know how. Don't let that deter you though, there is plenty of Bouldering, 4 or 5 autobelays, and we can belay you a bit.

Be advised, this is not a climbing course, and we cannot teach you how to belay or lead climb or anything like that. You'll have to sign up for an actual course with the gym for that.
