We planned and made the Bike Tour Manito 2020, just to visit this place. I was expecting more of the place, and its not what it is described in google map. though its still a good spot for swimming and any outdoor activities.. I didnt tried swimming due to time constraints, and because of that i cannot give a full review.
The spot is about 3km from the central town of Manito. Road is concrete and it goes up an down, so its a bit tiring. 
once you reach the marker on the road, you have to walk down the wet slippery small path about 400meters.
