Beautiful and close park! But it's a very small one most people stay in the cars!

Mariner Park is a hidden little cove off the Detroit River/Lake St. Clair and the Detroit/Grosse Point border. It's an awesome place to be crazy close to the boats and ships passing and a new restaurant nearby to dine well at! Off Alter and Jefferson Ave. - just add water...????

Cool little Park in Marine City. First time there lighthouse hunting. Lighthouse is all and central to city. Was there briefly enjoying the view. Long enough to see a couple freighters sail by.

I had a very poor experience at this park. My car was broken into (three windows completely shattered), and security was not able to assist. Detroit Police did not respond when contacted. I would not consider this park to be safe and would not feel comfortable bringing my family here.

Nice little park, benches at the water, playground, and restrooms. However, the amount of trash on the boardwalk in the parking lot and approach is disgusting and disappointing. There are trash cans available, clean up after yourself, and keep our parks clean!
