Fiona and I hiked the Grouse Grind on Wednesday. It was the first time for both of us. The Grouse Grind is about 3 kilometers of nearly vertical trail, with 2,800 feet elevation gain. It just goes up, up, up and up some more. We made it, and we're not even stiff after the hike. It sure felt sweet to get to the top! Hiking back down is not allowed, and I think it would be pretty scary even if it was allowed. We took the gondola back down. We'll definitely do this again!
