In mid-June, we decided to try our luck at Lily Lake, west of town near Darwell. Lily Lake is not easy to get into, requiring a 800m (2500-foot) carry, but I was keen to give it a whirl. Access is from the north off of Township Road 550 through the JBJ McDonald Conservation Area. I always see deer on this road (and we saw two today) so mind the ditches.
The conservation area is operated by the Edmonton and Area Land Trust (EALT). The EALT publishes rules about appropriate usage (you can find online) and this site bars wheeled vehicles. That means no carts and you need to carry your boats in. As you'll see, carts would also simply be unworkable after the halfway point. Note that 800m is a long distance to carry a hard-shell boat.
There is a good map at the car park (and good signage throughout). The parking lot holds maybe four cars and I've never seen more than one there. There are no washroom facilities--I'd guess the closest would be at the gas station in Darwell or the Darwell Launch on Lac Ste Anne (maybe a 20 minute drive).
Looking at the image below, you park at the red arrow at the top. Walk south on the yellow line, take the first SE spur and eventually access the lake at the Esther Lookout. We decided to walk in without boats to see what it looked like (which was a good decision).
Not every trip is a success, especially to a new lake. Overall, I'd be game to try this again, but probably by myself. I'd bring a lighter boat (that I can carry overhead--no way to carry two boats abreast for much of the trail)) and my waterproof hiking boots. Early spring or late fall would likely be a better time (water would have fewer lilies and the ground would be drier). I'd also bring bear spray again (there are bears, moose, and cougars in the area).
