Hiking, Biking & Beaches
Quick reference — the whole hub on one page
The cheat sheet: a one-liner for every rule in this guide, from the bike law to the beach, so you can scan it before you head out. Each card links to the full page, and the agency that runs the trail or beach always has the final word.
In an emergency
Out here, no one is watching out for you. If someone is hurt, lost, or in the water and in trouble, call 911.
Who runs it
Find the landlord first
- State parks, the Katy Trail, and swim beaches are Missouri State Parks; conservation and natural areas are MDC; the big backcountry is Mark Twain National Forest; riverways and historic sites are the National Park Service; lake beaches and greenways belong to the Corps, cities, and metro park districts.
- The rules come from whoever runs the place — match the spot to its manager, then check that agency for hours, closures, and what's allowed. (Full table below.)
Bike law
A bike is a vehicle
- Ride with traffic, as far right as is safe (RSMo 307.190) — except when you're turning left, passing, avoiding a hazard, or in a lane too narrow to share. Obey all traffic laws, and signal your turns and stops.
- At night — from a half-hour after sunset to a half-hour before sunrise — you need a white front light visible at 500 feet and a red rear reflector or lamp visible from behind, plus side and pedal reflectors (RSMo 307.185). A rear light is the smart choice.
- No riding a bicycle on a sidewalk in a business district (RSMo 300.347). Elsewhere, local rules decide — and you must yield to people on foot and give an audible signal before you pass. No motorized bicycle on a sidewalk, anywhere.
- A driver passing you must leave a safe distance and keep that clearance until safely past (RSMo 304.678). Missouri's law does NOT set a fixed three-foot number — three feet is a good rule of thumb, not the legal figure. A violation is an infraction, or a class C misdemeanor if there's a crash.
- Missouri has no statewide helmet law for bicycles — for adults or kids — though some cities have their own. Wear one anyway: most serious bike injuries are head injuries.
E-bikes
Three classes, treated like bikes
- By law (RSMo 301.010) an e-bike has working pedals, a seat, and an electric motor of less than 750 watts. It must carry a permanent label showing its class, top assisted speed, and wattage, and the motor must cut off when you stop pedaling or hit the brakes (RSMo 307.194).
- Class 1: Pedal-assist only — the motor helps while you pedal and stops helping at 20 mph. Class 2: Has a throttle — the motor can drive the bike, and stops at 20 mph. Class 3: Pedal-assist only, stops at 28 mph. No operator under 16 (a younger child may ride as a passenger if the bike is built for it), and it must have a speedometer.
- On the Katy Trail, Missouri State Parks allows electric-assist bikes up to 20 mph.
- On national-forest dirt, e-bikes are generally treated as motorized — allowed only where motor vehicles are. Check the travel map.
- There is no statewide e-bike helmet law — none, anywhere in the statute. Wear one anyway, and check local rules, since a city, park, or event can be stricter.
The big trails
Katy, Rock Island & the Ozark Trail
- The Katy Trail is about 240 miles long — the longest developed rail-trail in the country — running from Clinton to Machens through Jefferson City on flat crushed limestone. It has around 26 trailheads and four restored depots, is mostly wheelchair-accessible, and is part of the Lewis & Clark and American Discovery trails and the Rails-to-Trails Hall of Fame. Much of its route follows the Missouri River beneath the bluffs, crossing many old railroad bridges and trestles.
- The Rock Island Trail is the Katy's sister line. Its open section runs about 47.5 miles between Windsor — where it meets the Katy — and Pleasant Hill, toward Kansas City. The undeveloped corridor east of Windsor toward Beaufort is closed to public use until it's developed. When it's complete, the Katy and Rock Island together are envisioned as a nearly 450-mile connected loop.
- The Ozark Trail is Missouri's long-distance epic — more than 430 miles built, about 393 of them a National Recreation Trail, in roughly 13 connected sections of 8 to 40 miles each. The goal is to link the St. Louis area to Arkansas; joined with Arkansas's Ozark Highlands Trail, it would run about 700 miles.
- It's managed section by section. Hiking is the baseline use; many sections allow mountain bikes or horses, but not all do, and motorized vehicles are never allowed. Always check the Ozark Trail Association and the manager of the section you want.
Etiquette
Share it kindly
- The yield triangle: bikes yield to walkers and horses, and everyone yields to horses. Slow down for a horse, step to the downhill side, and speak calmly so it knows you're a person. Uphill traffic has the right of way. Keep right, pass on the left, and call out — 'on your left!'
- The mud rule splits two ways: hikers stay on the trail and walk straight through the mud (going around it just widens the trail), while mountain bikers who are leaving ruts or mud tracks should turn around and ride another day.
- Leave No Trace: pack out everything you bring in, and stay on the marked trail — don't cut switchbacks or make new paths.
- 'No glass' isn't a blanket trail rule — it applies at beaches, swim areas, float streams, and anywhere it's posted.
- Leave what you find. On most MDC conservation areas you may take nuts, berries, fruits, edible wild greens, and mushrooms for your own table; on Missouri Natural Areas, edible greens are off-limits, but nuts, berries, fruits, and mushrooms are fine unless the area restricts them; state parks are look-don't-take — no removing plants, rocks, animals, downed wood, or artifacts without written permission. (See the Foraging hub for the full rules.)
Dogs
Leashed, and off the swim beach
- Dogs stay leashed — MDC sets a 10-foot maximum, and state parks require a leash at all times, with no dogs in park buildings or on swim beaches. Pick up and pack out the waste (in the backcountry, bury it 100 feet from water and trails).
Beaches
No lifeguard on the sand — swim at your own risk
- Missouri is landlocked, so 'beaches' means lake swim beaches and river swimming holes — and almost none have a lifeguard, so you swim at your own risk.
- Beach rules: swim at your own risk — don't assume a lifeguard is on duty (Missouri state-park beaches and natural swim areas have none; private beaches, city pools, and events differ, so you're the lifeguard for your group); no pets on swim beaches; swim in the designated area, away from marinas and ramps; no glass; and check the posted water-quality information.
- Some beaches, ramps, and Corps areas have free life-jacket loaner stations. Treat them as a backup, not your plan — bring properly fitted jackets, especially for kids, and check the specific beach.
Water safety
You're the lifeguard
- No lifeguard means you're the lifeguard. Drowning is fast and silent — it rarely looks like it does in the movies. Assign a water watcher who isn't on their phone, watch kids and weak swimmers constantly, and always swim with a buddy.
- Never dive into unknown water. Enter feet-first, every single time — lakes and rivers hide rocks, stumps, and depths that shift overnight.
- Respect the drop-off and the cold. A beach can go from ankle-deep to over your head in one step, and deep or spring-fed water stays cold enough to sap your strength fast.
- Skip the alcohol around the water, and keep a sober adult watching it.
- If someone's in trouble: Reach, Throw, Don't Go. Reach with a pole or a branch, or throw something that floats — don't swim out unless you're trained, because a panicking swimmer will pull you under. If you must go in, bring flotation. Call 911.
Hiking safety
The short list of what goes wrong
- Beat the heat: hike early, take shade breaks, wear a hat and light clothing, and carry plenty of water — and actually drink it.
- Ticks, chiggers, and mosquitoes: use repellent, wear long pants on brushy trails, and check yourself for ticks after every hike. (See the Wildlife hub for tick-borne illness, alpha-gal, and removal.)
- Snakes and poison ivy: watch where you put your hands and feet, give snakes room and never handle one (the copperhead is the most common), and remember 'leaves of three, let it be.' (See the Wildlife and Foraging hubs.)
- Don't get lost: on remote trails carry a map and compass or a GPS, follow the blazes, and don't count on cell service. Tell someone your route and when you'll be back.
- Flash floods and creek crossings: Ozark creeks and low-water crossings rise fast — don't cross fast or rising water on foot or by car. Turn Around, Don't Drown. (See the Rivers & Tubing hub.)
- Wear orange in hunting season. (See the Hunting hub.)
First, find the landlord
Who runs the trail or beach
The rules on a trail or a beach come from whoever runs it. Match the place to its manager, and you'll know where to check for hours, closures, and what's allowed.
| Where you are | Who runs it | What to know |
|---|---|---|
| State parks, the Katy Trail & swim beaches | Missouri State Parks (DNR) | No entrance fee and no lifeguards. Dogs leashed at all times — not in buildings or on swim beaches. Quiet hours around 10 p.m. |
| Conservation & natural areas | Missouri Department of Conservation (MDC) | Usually open 4 a.m.–10 p.m. (with exceptions for hunting, fishing, and camping). Pets on a 10-foot maximum leash. Bikes only where posted — Natural Areas may exclude them. Check the area map. |
| The big backcountry | Mark Twain National Forest (USFS) | The best long mountain-bike and backpacking trails, and much of the Ozark Trail. |
| Riverways & historic-site trails | National Park Service (NPS) | Ozark Riverways trails and historic sites like Wilson's Creek Battlefield. |
| Lake beaches, greenways & city trails | Corps of Engineers, cities & metro park districts | Corps lake swim areas and metro greenways (Great Rivers Greenway in St. Louis, MetroGreen in KC, Columbia's MKT). |
| The Ozark Trail | The Ozark Trail Association, with the land managers | Managed section by section — check the OTA and the manager of each section. |
E-bike access, place by place
Where you can ride an e-bike
This is the part of the law that's still settling, and it changes by manager. When in doubt, check the agency that runs the trail before you ride.
| Where | The rule |
|---|---|
| Public roads | Same rules as a bicycle — ride with traffic, far right, and obey the signals. |
| Bike & multi-use paths | Class 1 and 2 are generally allowed unless a local authority restricts them; Class 3 may be restricted on a path. |
| The Katy & Rock Island trails | Electric-assist bikes are allowed up to 20 mph (Missouri State Parks). |
| Mark Twain National Forest dirt | Treated as motorized — allowed only where motor vehicles are. Check the travel map. |
| MDC conservation areas | Only where posted — check the area page. |
| Natural-surface singletrack | Often managed as non-motorized; the e-bike law doesn't cover these, so the land manager decides. Check first. |

Before you go
Missouri Porch explains; the agency that runs the trail or beach decides.
Last checked: 2026-06-18. Trail rules, e-bike access, and beach conditions change with the season and the manager — and out here, no one is watching out for you. Check before you go, carry water, and watch the kids.
This is a plain-English summary — not the law, a medical authority, or a guarantee of safety. Trail rules, e-bike access, and beach conditions change — check the managing agency before you go. In an emergency, call 911.
Heads up: This is the short version — each card links to the full page, and the agency that runs the trail or beach decides. The passing law is a safe distance (not a fixed three feet), there's no statewide bike or e-bike helmet law (wear one anyway), and there's no lifeguard on the sand.
