Does anyone know how the walking trail distance? Mile or 1/2 or what plz.

There's a trail map with distances for West Lake Park on the Generation Park website: https://www.generationpark.com/parks-trails It ranges from 0.61 mi. to 0.96 mi. depending on the route you take.

I'm not sure but i would give it somewhere bt 1.5-2 miles, that is the loop around the lake if that's what you mean.
