I usually spend up to 2 weeks each camping season at St.Malo over the past few years. In fact I just did a 2 week stint there and just got back.
For those of you unfamiliar with the area, I will try to fill you in.
The lake at St.Malo does not allow gas powered boats. Only electric/wind or human powered, so it's quite.
The town of St.Malo is just on the other side of the hiway, so a two minute drive from the sites. There are two Grocery/General stores in town, so if you forget a few things, don't worry. There is also a laundry mat and a bar/vendor if anyone wants to pick up some frosty ales.
Almost everyone in town takes Credit card and interact/debit.
Firewood can be bought at the campground for $6 a bundle of 4 bundles for $20. It is cash only and is right beside the campground check in office. Firewood can also be bought in town from the local residents selling it from their driveways. Usually $5 a bundle.
The campground has two beaches, The beach by the rally site(east beach) is less desirable. It is rocky and gets deep fast. The other beach (west beach) has better sand is much longer and doesn't get deep as fast. The west beach can be seen from the east beach and is only a short walk.
At the end of the west beach you can rent a few different 2 seater peddle boats for $15 an hour to tour the lake.
By the west beach is an ice Cream parlor called Holy Cow. They serve soft and hard ice cream as well as other cold treats, beverages and burgers n fries. It's a bit pricey, but the Oreo Cookie Sundae is amazing!! 6 oreo cookies, ice creame, whip cream and a few cherries. Best shared with two people!
For those of you with kids, St.Malo is the place for you. Along with the two beaches, there are a lot of bike trails and several newly updated play ground structures located at both beaches.
There are fish in the lake, but fishing is not the greatest. There are a lot of reeds along the shorelines, so shore fishing is not all that good. If you had a canoe or a little boat, then jigging a little bit out is your best bet.
There are a few groomed walking trails through the forest.
On the south west corner of the campground is the dam/spill way. It is very scenic at the bottom as the water runs down the spillway. Photo Op
There is a par 3 golf course just east outside of the park.
There are 3 shower stations in the park, one is located by the rally and the other two are located in the 1-10 bays area.
There are several water running washrooms scattered in the park, including one near the rally as well as a few out houses.
One of the only negative things about the park is the poison ivy. Where the rally is being held is the open area of the campground, so none is around, but right at the bush line, it's everywhere. If you dont go bush crashing in shorts, you'll be fine.
Hope this helps a few out.
See ya there!
