The Neal Smith Trail: the paved lakeside ride through Johnston to Big Creek.

The Neal Smith Trail is the paved backbone of central Iowa's trail system: about 26 car-free miles running from Des Moines up the Des Moines River, along Saylorville Lake, to Big Creek State Park. It runs right through Johnston, with a local trailhead near the Saylorville dam. Here's where it goes, what you'll see, and how to ride it from town.

The quick answer

The Neal Smith Trail is a roughly 26-mile paved trail running from Des Moines north along the Des Moines River and Saylorville Lake to Big Creek State Park. It's paved the whole way, good for biking, running, skating, and walking year-round.

The route

Where does the Neal Smith Trail go?

The trail runs north-south along the Des Moines River. At its south end it connects to the John Pat Dorrian Trail, giving a safe, scenic route from downtown Des Moines out to the lake. Heading north, it passes through Johnston, hugs Saylorville Lake and ends at Big Creek State Park, with the Saylorville Lake Visitor Center, near the dam in Johnston, a popular rest stop along the way.

The scenery

What will you see on the Neal Smith Trail?

For a metro trail, the Neal Smith is scenic, moving through river bottomland, shaded forest, oak uplands, and prairie, often with the lake in view. It's paved and generally friendly for road bikes, hybrids, strollers, and inline skates, though the stretches along the lake are genuinely hilly, so it isn't all flat. In winter it's used for snowshoeing and cross-country skiing.

From Johnston

How does the Neal Smith Trail connect to Johnston?

The Neal Smith Trail has a Johnston trailhead near the Saylorville dam, so from town you can link onto it and reach Saylorville and Big Creek to the north, or ride south toward Des Moines. It ties in with Johnston's own network, the Beaver Creek Greenbelt, Johnston Interurban, and Trestle to Trestle trails, so you can string together a longer car-free ride. See our Johnston trails guide for the full map, and the Saylorville Lake guide for the beaches, ramps, and campgrounds along the way.

Plan it

Trailheads and tips

You can hop on at multiple points, including the Johnston trailhead near the dam, spots near Saylorville and Big Creek to the north, and along the river toward Des Moines. Bring water for the longer stretches, plan an out-and-back that matches your legs (it's a long trail with real hills near the lake), and check the Army Corps for any closures near the lake, since water levels and construction can affect access. For a nearby marquee ride, pair it with the High Trestle bridge out by Madrid.
