Okay, first off I'm not a west-sider so finding the place put me at a distinct disadvantage. I was persistent and did find it, but for newbies the signage could definitely use an upgrade.
The park itself has a large fenced in gravel space - great for big dogs who love to run in a pack like my husky- endless back and forth sprints to and fro with new found friends make a happy dog and a tired, mellow friend in the evening! For small dogs- the space set aside is a bit on the depressing / high functional end. I'd choose Canine Meadows in Kirtland which has more grassy romping room for the little ones.
Here at Tremont, there are some benches that afford a bit of shade for the owners who prefer to observe sitting down.
Power plant adjacent is a little too industrial if you're looking for a semblance of pastoral quiet. But what the hell, still a great park with friendly dogs.
