After a short break for lunch we headed to Steelhead Falls, also in Mission. These falls are on the Reservoir Trail at Hayward Lake. There is a fair amount of info online on hiking the whole 10km length of the Reservoir trail (which includes the falls) but not that much about the most direct route to Steelhead Falls so let me help you out: You want to park at a small parking lot on Dewdney Trunk Road just east of the Blind Slough Dam (about 1.3km east of the dam, just after you go under the power lines). There’s a sign on the road for BC Hydro’s Hayward Lake Recreation Area so you should be able to find it.
From the parking lot its an easy hike down hill to join the Reservoir Trail. Head left (south) on the Reservoir Trail for about a kilometre to get to the signed spur trail for Steelhead Falls. The stairs and boardwalks down to the falls are a bit slippery and are showing their age but they still provide a couple great viewpoints of the falls. You have descended about 50m to get to the falls so your return trip will be all up hill.
