St. Louis isn’t just about baseball and toasted ravioli — it’s also a surprisingly great hiking hub. Within 30 minutes of the Gateway Arch you can climb bluff-top lookouts, wander shady riverside bottoms, and tackle rocky Ozark-style terrain. Whether you’re a local looking for a new weekend loop or a visitor who wants a nature fix between museums and BBQ, use this guide to four standout hikes around the metro. Each section includes real-world tips drawn from recent trail write-ups and reviews, plus a live map so you can drop the pin and go.
Castlewood State Park — River Scene Trail (Ballwin)
Why go: If you only have time for one St. Louis hike, make it the River Scene Trail at Castlewood State Park. This classic loop climbs to bluff overlooks of the Meramec River, then drops to a peaceful riverside path through bottomland forest. Expect broad views, limestone outcrops, and a tangible sense of the area’s 1920s resort era — you’ll pass remnants like the “Grand Staircase” and old foundations along the way.
The experience: Missouri State Parks describes River Scene as a loop with “the park’s most spectacular views” as it traces the top of the bluffs for roughly a mile before connecting to the lower floodplain section. Plan on a moderate workout with stairs and some steep grades, especially on the climb from the valley up to the ridge (or vice versa). Trail mileage is posted at about 3.25–3.4 miles depending on entry point and connectors.
- Distance/Elevation: ~3.25–3.4 miles; moderate, with stairs and short steep pitches.
- Good for: First-time visitors, sunrise/sunset photo stops, families with hiking experience.
- Watch for: Seasonal flooding on the lower section; wooden stairway can be slick after rain.
What hikers say (clickable): “Best year-round bluff views I’ve hiked in Missouri” reads one local thread. AllTrails users routinely rate it highly for scenery and variation; see the River Scene Trail page for recent conditions.
Pro tip: Come mid-October for fiery foliage from the bluffs, or launch just after dawn on clear days for soft light on the Meramec. Weekends can be busy — start early or try weekdays.
Cliff Cave County Park — River Bluff & Mississippi Trail (South County)
Why go: For big-river scenery minutes from the city, Cliff Cave County Park strings together paved greenway, forested single-track, and bluff-edge views over the Mississippi. It’s one of St. Louis County’s designated Heritage Parks and anchors a section of the Mississippi River Greenway, with wildlife viewing that ramps up during spring and fall migrations.
The experience: Mix and match the River Bluff, Spring Valley, and Mississippi trails for your preferred distance. Families often start on the paved greenway portion for an easy out-and-back, while hikers seeking elevation head for the River Bluff segment. Facilities include year-round restrooms and a reservable shelter near the trailheads — convenient for group meetups.
- Distance/Elevation: 2–5+ miles depending on loop; mostly easy to moderate, short climbs to the bluffs.
- Good for: Stroller-friendly paved miles, birding, sunset river overlooks.
- Watch for: Active train track crossings and occasional closures around the namesake cave (tours are seasonal).
What hikers say (clickable): One reviewer calls it “a great outdoor area in South County… we go there quite often to walk the 5.1-mile loop” on Yelp. On TripAdvisor, visitors highlight clean restrooms and a pavilion with plenty of tables; see recent comments on the Cliff Cave County Park page. For official details and maps, check St. Louis County Parks’ park page and trail map.
Pro tip: Bring binoculars — the greenway here is known for herons and migrating raptors along the flyway. After heavy rain, stick to the paved sections and skip low riverside spurs that can collect mud.
Rockwoods Reservation — Lime Kiln Trail (Wildwood)
Why go: Want a taste of Ozark hills without the long drive? Head to Rockwoods Reservation, a Missouri Department of Conservation site with caves, springs, and rugged singletrack. The Lime Kiln Trail is a signature loop that threads past a 19th-century stone kiln and through shady hollows with seasonal water.
The experience: This 3.1–3.2-mile loop starts near the main lot and immediately climbs into rocky, rooty terrain before easing through cool, wooded valleys. It’s a stout workout for a short distance, and a solid alternative when Castlewood is crowded. Keep your eyes peeled for interpretive signs and the massive limestone kiln near the end of the loop.
- Distance/Elevation: ~3.2 miles; moderate to moderately strenuous with short steep grades and uneven footing.
- Good for: Hikers who want a wilder feel, history buffs, trail-running practice on technical surface.
- Watch for: Slippery leaves and rocks after rain; some sections can be busy on fall weekends.
What hikers say (clickable): “Excellent… a challenging option” notes one TripAdvisor review of the Lime Kiln loop at Rockwoods here. AllTrails reviewers call the route “rugged in the beginning and end” and “an awesome workout” — browse recent reports on the Lime Kiln Trail page. For official background, MDC’s site outlines the area’s caves, overlooks, and total trail mileage: see the Rockwoods Reservation page.
Pro tip: The conservation area hosts occasional guided hikes from the Lime Kiln trailhead — a low-stress way to explore if you’re new to the terrain. Check the events calendar before you go.
Forest Park — Wheels & Heels Path and Nature Loops (City of St. Louis)
Why go: Need a car-free option inside city limits? Forest Park’s multi-use paths and dirt connectors offer easy mileage near the zoo, art museum, and boathouse. It’s perfect for travelers staying downtown who want a leg-stretch without leaving the urban core.
The experience: The popular Wheels & Heels Path forms a broad loop that links lawns, lakes, and woodlots, with spurs into quieter pockets for birding. Pair a lake circuit with short woodland connectors for 3–5 miles at a conversational pace. Expect runners, strollers, and cyclists; etiquette is key on fair-weather weekends.
- Distance/Elevation: Choose your own loop; the Wheels & Heels route is commonly done in the 4–6-mile range; mostly flat.
- Good for: First-morning shakeout walks, families, anyone combining museums with outdoor time.
- Watch for: Crowds near the boathouse and cultural institutions; mind bikes and keep right.
What walkers say (clickable): AllTrails users rate Forest Park’s loops highly for easy access and scenery; see top options on the Forest Park page and the best walking trails list.
Pro tip: Sunrise or the golden hour before sunset gives you calmer paths and photogenic light across the Grand Basin. Add a museum visit post-walk for a perfect city-nature combo.
When to Go, What to Bring, and Local Etiquette
- Best seasons: October–early November for color at Castlewood and Rockwoods; April–May for wildflowers. Summer is beautiful but humid — start early and hydrate.
- Footing: Expect roots, rocks, and stairs on bluffs and at Rockwoods. The paved sections at Cliff Cave and Forest Park are great after heavy rain.
- Safety: Stay back from bluff edges, especially with kids or dogs. Floodplain segments can hold water; check recent reports on the linked trail pages.
- Etiquette: On shared paths, keep right and announce passes. On natural-surface trails, yield to uphill hikers; mountain bikers yield to hikers and equestrians.
- Facilities: Year-round restrooms at Cliff Cave; seasonal at other parks. Always pack out trash and stay on signed routes.
