Going up D trail to sand lake is easily doable, have a bit to eat at restaurant there. Can head out check out the ice caves and ride back via d. If d's in good shape it's nice easy ride.
Plan b could trailer to info centre at 518 and do easy ride to ice caves and some of scenic d123 trail to Burks falls. That one is one of my favourite for stunning views. I would avoid big hill if you don't have studs though. I think if you take al300 it avoids hill but I can't remember exactly where it is. It's a stunning hill if you can navigate it. I am pretty sure it is between 300 and d north. I have had a few oh crap moments on that hill but never ended up in reburb. Lots of riders wipe out on it, if it's icey it's a tough go 🤡
