We’re not sure what is provided for the Grand Lake St. Mary’s State Park cabins. I recommend you call the park directly to confirm: 419 394-3611
We stayed here for a week in mid June of 2019. The campground is divided up into 2 main distinctive sections. One (by the pool area) are mostly “pull-thru’s. The pull-thru’s are somewhat short, so if you have a RV unit over say 35′ there will be no room to park your toad or truck on your paved pad. And this section has no trees. The spacing between campsites was rather close. But, it is right next to the new $1.5M pool. All the sites in this section are level. There was a new shower building for this section.
The other section of campsites including some full service sites is situated on a very slight hillside. Nothing crazy, but 2/3 of these sites will include the need to block up one side of your RV’s wheels. The second negative is most of the sites in this section are 90 degree back in sites, so if it’s wet the wheels of the RV drop into the mud off the pavement. Overall spacing between sites in this section was average to larger than average. About 3/4 of the sites in this section had widely spaced large trees offering some shade. The bathrooms and one showerhouse in this section were the old block type buildings common in Ohio State Park system.
The new $1.5 pool complex with a circular slide is the star of the place. Without the pool locals say the place would only fill 50% on summer weekends, now its been full on the weekends since the pool was put in last summer (2018). Access to the lake is either by the first row of campsites or just after the pool. The lake itself had some algae bloom issues back about 4 years ago , since then it has improved, but I still would not swim in it. The water still has a green color. I did kayak in it 4 of my 7 night stay. The short hiking trail is, how should say it, in very poor condition, evident of no upkeep in the last 10 years.
Overall I gave the place a 4 star only because of the pool, otherwise a 3 would be a fair grade. Near by in St. Mary’s there is a community park (KC Geiger Park) mini golf coarse (18 holes $2 er adult) on a very professional level. During the week days ( 10am to 2:00) the local “special needs” people run it with proceeds going to their organizational. There is also a long 18 hole disc golf course there too. In the near by town of New Bremen there is the Bicycle Museum of America. Very well done exhibit ($3 per person). The whole area running north and south is where you will find the old Miami Erie Canal with many locks in the downtown city parks. It was in operation from the 1840’s to 1915 connecting the Ohio River to Lake Erie.
Was checking to see if pool is open at campground? We have reservations this weekend and have little ones so was checking since it’s going to be so hot
Hi Cindy,
According to Ohio State Parks page, the pool / splash pad are closed, but you may want to double check and call Grand Lake St. Marys State Park directly at: (419) 394-3611
Are small dogs allowed on the beach and to swim in the lake?
Hi Connie,
Not sure. You may try calling the park office to inquire: 419-394-3611
What is all included in the larger camper cabins. We have Camper Cabin 3 rented and was just double checking what all was in them. Thank you.
Hi Karrie,
The cabins at Grand Lake St. Marys State Park have electricity, lighting, a microwave, refrigerator, picnic table, fire ring, and gas BBQ grill. The maximum vehicles allowed is 2 and occupancy is 5. There are also beds, but not linens. Hope this helps!
WHAT WEEKEND IS TRICK OR TREAT AT GRAND LAKE ST. MARYS THIS YEAR 2020
Hi Gail,
We’re not sure if Grand Lake St. Marys State Park will have their annual Trick O’ Treat day this year due to Covid restrictions. I recommend calling the park directly to confirm at: 419-394-3611.
I can not find any information regarding the use of the pool at the State Park camp ground in St Marys. It is for Camper only? What is the fee? What can be carried in? Food? Coolers? Is there a concession stand?
Hi Ruthie,
Grand Lake St. Mary’s State Park does have a swimming pool at the campground. There’s also a splash pad and a water slide for kids 48″ in height and up. The swimming pool has lounge chairs, umbrellas, restrooms and outside showers. It is open 11am to 9pm and lifeguards are on duty. Not sure though if it is only available for campers. I recommend calling the main office to confirm: 419 394-3611.
