I'm so glad that Wendy reviewed this on Yelp! I didn't realize I could review parks (didn't think they had a specific address).
I love Sandy Beach! I say this as a cyclist. This park is on the Elbow River Pathway between Stanley Park and the Glenmore Reservoir. When cycling through this park I have a few tips for you.
#1 - Keep to the west side pathway. There are two paths that pass through the park, one of which is closer to the river. The one closer to the river is busiest with pedestrian traffic.
#2 - Dismount on the suspension bridge, especially if there is another cyclist on the bridge. It's super narrow. There are signs that say to do this.
#3 - When riding Southward there is a large steep hill at the end of the park. Go ahead and put yourself into low gear and challenge it! It's a toughy, but short and worth it! I always feel like Superman after I hit the top!
I have visited this park a few times to use the outdoor grills. I typically bring charcoal briquettes because I'm cycling or walking in which is light and more compact that bringing firewood. I'd suggest using firewood when possible if you want to cook faster or your food is very raw, like steak. I typically bring hot dogs, marshmallows and quick to heat items. There are bon fire pits as well but you need to get there in the early afternoon in peak times to secure one.
Be sure to bring your bathing suit! The beach is beside the suspension bridge which isn't particularly sandy, but a nice cool shallow dip in the Elbow River!
