Ohio has 76 state parks, and the famous ones get mobbed. About 30 minutes from both Dayton and Cincinnati, Warren County Armco Park in Lebanon offers a calmer alternative — a 311-acre county park that locals have called one of the county's best-kept secrets.

The land has history baked in: Native American habitation, then a 19th-century Shaker settlement, then a private employee park built in the 1960s by steel manufacturer American Rolling Mill Company (ARMCO). The county bought it in 2008 and kept the name. Today it packs in a lake, golf, trails, a waterfall and enough courts to keep a sports-mad family busy for a day — all with free entry.

Water is the main draw. Armco Park Lake covers 110 acres, and you can fish from the bank or launch your own craft for a small fee. No boat? The dock rents jon and pontoon boats, rowboats, canoes, kayaks, paddle boards and pedal boats by the hour. Expect largemouth and spotted bass, bluegill and white crappie; bass must be released, and catfish and crappie face size and quantity limits. You won't need an Ohio fishing licence here, but you do need a park fishing pass — sold at the dock from April 1 to September 30 — and shoreline catch-and-release is free from October 1 through March 31. Kids aged 5 to 15 fish free. Head to the lake's south end for the quietest water.

On dry land, golfers get an 18-hole course running along the lakeshore, open April through October, at $16 for nine holes or $24 for eighteen — a genuine bargain. There's also a free disc golf course, plus basketball, pickleball, tennis and sand volleyball courts, a four-diamond softball complex, and picnic shelters with grills and an indoor event pavilion.

Hikers have two easy options. The Woodland Trail is a shaded, roughly one-mile loop through woods along the lake's northern edge. Across the water, the Solar Pollinator Discovery Trail is a short educational walk with seven interactive stations covering monarch butterfly migration, pollinators and green energy — a nice half-hour with kids.

The park's location is the real hook for travellers: Lebanon itself has a handsome historic downtown, Dayton's museums and food scene is half an hour one way, and Cincinnati's celebrated street art is half an hour the other. Armco Park slots neatly into an afternoon between the two, or as a cheap, low-key base for a Southwestern Ohio weekend. Anglers, casual golfers and families with small boats will get the most out of it.
