Scioto Autobon Park
This is the best place in my opinion if you want a skyline background mixed with flowers, trees, and ponds.  Not to mention the architecture of the nature center is very unique.

Inniswood Metro Gardens

Possibly the most beautifully landscaped free park in Columbus, Ohio.  Highlights of this park include a waterfall, rare colorful flowers throughout 75% of the park, and plenty of unique architecture.  This is one of my favorite venues to                                                                                          shoot engagements and families.

Arch Park - Downtown Columbus - Arena District

For those who want a high class urban setting, Arch park is the place.  Highly detailed structures, brick buildings, neon signs for a bit of flare, and artistically placed trees.  This park is a photographers dream come true.
