We have been twice - back in the day when it was known as Radium Hot Springs. It used to be a place where you went after a day of skiing/mountain biking/hiking etc. Now it been spruced up to be a destination in and of itself (see

I haven't seen the renos so I can't say how well the zip line works! My advice? Plan to spend 2 hour and bring along towels, a lock, flip flops and snacks for the kids. All of these cost extra (of course). For our last visit (2017) parking was free. Hopefully that has not changed?
