Forgive me for yammering on about the camping, but I wanted to post some pics here to share with a friend. Here you go, M.
Miquelon- my June 2007 review, so some information is out of date.
It's clear water (salt water), shallow so great for little ones, a huge beach with nice soft sand, picnic tables right on the beach (a ways away from the water though), a big playground near the water, and there are walking trails. They do have campsites but they are not very private and all gravel, which sucks for tenting. They only have one campsite loop open at present as they are still doing renovations (I heard they are booked for the summer anyway).
It's about half an hour or so SE of Edmonton.
Playground near the lake(linked as it's a big photo). You can see the picnic tables behind the playground dotted along the beach.
Clear water!

Walking trail- there are some backcountry trails but it was too mosquito-y when we went. There is also a little store with ice cream and stuff and you can walk along the walking trails to get to it. The park usually has flush toilets and showers but they weren't functional when we went in June.

There are a couple of other small playgrounds amongst the campsites as well. Miquelon is really nice but crazy busy on a weekend, due to it's close proximity to the city. We've never overnight camped there, but it's a nice beach to visit on a weekday when it's not so busy.
Carson Pegasus- these are from 2006

Lake

Playground on beach

Swim area/beach. It's pretty small but the lake is clear and shallow. Rocky bottom in swim area, not sand.

Tip of the peninsula- you can hike up to the top, through another walk-in area. There is another hiking trail to the right of the map above but when we started on it we saw a sign warning a cougar was in the area, so we turned right around

Looks like people feed the ducks :) I wanted to too but we read a sign that feeding them peope food means they produce fewer eggs and don't gain weight fast enough, etc so I resisted.

Walking trail

Walk-in tenting site right beside the water

The lake is stocked with some kind of fish I can't remember, so there were lots of people boating and fishing. Lots of big rvs, I think I only saw one other tent! There is a store that sells ice cream, some food items, fishing supplies and a few toys.
I really liked the campsite. The service was so-so (the people in the check-in place were semi-rude when I called to book, when we got there she didn't know how far the walk-in sites were from the parking lot as she "had never been up there" and didn't know what the weather forecast was for the next day) but the campsite was clean and well-maintained. We were really happy with our site, as it was far from other campsites but close to the playground, trails and showers/bathroom. It was super-quiet being that it wasn't a weekend and it was only June so that was nice too. It was kind of a bummer to come back to the city and be surrounded by traffic and fast food joints after spending a couple days outdoors in the pretty forest by the lake.
Edited to add: firewood used to be free, but either this year or the last they started charging and it's 6$ a bundle now.
It is about 200 km north of Edmonton, almost all of it on major highway. It is easy to get to. If we didn't stop it would have taken 2.5 hours (half hour to get out of the city, 2 hours to campsite). It took us 4 hours because we stopped for coffee and lunch. Next time we plan to leave right after breakfast and pack sandwiches to eat at the site for lunch when we get there.
