The city of Cleveland has plenty of parks, plenty of playgrounds. Lakewood Park is by far my favorite. It has a baseball diamond, volleyball court, basketball and tennis courts. Their pool is amazing. A great playground for the children and even a Pavillion for families to throw parties. The greatest gem? The solstice steps that overlook Lake Erie.
If you love silence, and water. The solstice steps will be your second home. My family and I literally go weekly and watch the sunsets. Lakewood Park truly has everything, they even have the women's Pavillion if you want to throw indoor parties. The indoor Pavillion even has a full kitchen and men's/women's bathrooms. The city also hosts neighborhood movies in the park which is very nice if you want to mingle with neighbors and others in the city. Also. One final key addition? Lakewood Park has about 8 pokestops, and even a gym to do battle. If that doesn't truly make it great, I don't know what can.
