Do not go beyond this sign” is a prohibition. “End of maintained trail! Trail beyond this sign is not maintained” means maintenance ends and the route may demand greater navigation and backcountry skill. “End of Trail! Do not go beyond this sign—please turn back” is an instruction to reverse direction.
A barricade, fence, rope or closure sign marks the boundary. Stop at it, do not walk around it, and find the signed alternate route or the land manager’s current closure map. Closures can protect visitors, rescuers, wildlife habitat, eroding slopes and newly built trail surfaces. Treat the status as changeable and check the responsible agency immediately before leaving.

Read the exact wording before interpreting the symbol
Trail signs are often designed to be understood quickly, but similar-looking notices can require very different decisions. Start at the top of the sign and read every line, including dates, permitted-user icons and arrows. Do not infer that a route is open merely because a tread is visible or because other people have continued past the notice.

“Area Closed! Do not go beyond this sign”
This is a direct prohibition. The sign identifies a closed area, and the boundary begins at the sign or barrier. Do not proceed on foot, by bicycle, on horseback or with a vehicle unless the notice explicitly permits your user type. Look for a detour or return to the last signed junction.

“End of maintained trail! Trail beyond this sign is not maintained”
This wording does not necessarily say that every step beyond the marker is legally closed. It tells you that the managing agency no longer maintains the route. Expect fallen limbs, washed-out tread, missing signs, unstable surfaces or dense vegetation. Continuing is appropriate only when the agency’s information confirms that the route is open for your activity and you have the navigation, terrain and emergency skills it requires. A maintained trail ending is not permission to ignore a separate closure farther ahead.
“End of Trail! Do not go beyond this sign—please turn back”
This is an end point, not a suggestion to explore. Turn around at the sign. A visible continuation, social path or old map line does not override the instruction.
Why words outrank colors and shapes
Color conventions and pictograms can vary between parks, counties and trail systems. The written instruction states what the manager wants you to do at that location. Read the legend on the associated map to interpret symbols, then use the sign’s text and dates to make the immediate decision.
| Message on sign | What it tells you | Immediate action |
|---|---|---|
| Area Closed! Do not go beyond this sign | The area past the boundary is prohibited. | Stop and use an authorized detour or turn back. |
| End of maintained trail! Trail beyond this sign is not maintained | Routine maintenance ends; conditions and navigation may be significantly harder. | Confirm the route’s legal status and your capability before proceeding; obey any additional closure. |
| End of Trail! Do not go beyond this sign—please turn back | The designated trail ends at the marker. | Turn around; do not follow an unofficial continuation. |
A barricade is a boundary, not an obstacle to solve
When a closure sign is accompanied by a gate, fence, rope, cones or other barricade, the physical barrier confirms the boundary. Never squeeze through a gap, climb over, move or unlock it. A barrier may protect you from rockfall, unstable construction, wildlife-management work or a drop that is not obvious from the approach.
Do not create a parallel footpath around the obstacle. Walking around a gate widens the disturbed area, tramples vegetation and can start an erosion channel. Cutting a switchback is particularly damaging: it concentrates water on a steep shortcut, loosens soil and creates a fall hazard. Los Angeles County warns that shortcuts and cut switchbacks can cause erosion, create hazards and lead to further closures.

Why a trail may be closed
Closure notices are issued for more than one reason, and the reason affects how long conditions may last. Point Reyes National Seashore identifies visitor safety, endangered-species protection, erosion prevention and allowing newly built trail sections to harden. Boulder notes that some closures are emergent, responding to immediate risks to visitors, wildlife or natural resources.

- Visitor safety: Rockfall, fire effects, flooding, unstable bridges, dangerous trees or other hazards may make a route unsafe before a permanent repair is possible.
- Wildlife and habitat: A closure can protect endangered species, nesting areas or sensitive habitat from disturbance. The restriction may apply even when the trail surface looks walkable.
- Erosion control: Saturated slopes and damaged tread can deteriorate rapidly under foot or bicycle traffic. Keeping people off allows drainage and stabilization work to succeed.
- Construction and trail hardening: Newly built or repaired tread may need time to set before use. Entering early can undo the work and extend the closure.
- Emergency or operational conditions: Managers may close a route with little notice when conditions change. An old sign, cached map or previous trip report cannot establish today’s status.
A repeatable method for reading a detour map
Use this sequence whenever a sign directs you to a map, when you are planning around a known closure, or when a navigation app conflicts with field information.
- Identify the managing agency and map date or version. Read the title block, revision date and agency name. Use the current official park or land-manager map first. A store-bought map can be useful for broad geography but may be inaccurate about closures, reroutes or newly built segments.
- Read the legend before tracing a route. National Park Service maps commonly distinguish hiking routes, trailhead information, maps, pedestrian crossings and safety or caution alerts. Learn the line styles, colors, icons and closure marks used on that particular sheet; a red line on one map is not automatically the same as a red line on another.
- Locate yourself and the intended destination. Identify the trail name, starting trailhead, junctions and endpoint before looking for the closure. This prevents accidentally treating a nearby road or spur as the official substitute.
- Find the closure marking and any dates. A red slash through a permitted-use symbol means that use is closed. Read seasonal dates printed on the sign or map. A route may be open to hikers but closed to bicycles, horses or motor vehicles, or open only during a stated season.
- Trace the detour one junction at a time. Follow the arrows or highlighted line from the closure to the next named junction, then to the destination. Confirm that the detour reconnects with your objective and never crosses into the closed segment.
- Check who may use the substitute route. Verify the permitted-user symbol and any restrictions on dogs, bicycles, horses, motor vehicles or group access. A detour for pedestrians is not automatically legal for every other user.
- Compare practical demands. Note distance, elevation gain and loss, surface, exposure, water availability shown on the map, and the stated difficulty. A short-looking reroute can add a steep climb or rough surface that changes whether your group can complete it safely.
- Confirm current conditions with the managing agency. Detour plans and signs are part of formal trail projects, and agencies such as Boulder publish closure maps and signed detours. If the map, field sign and agency notice do not agree, ask the agency which item governs before entering the area.
How to judge whether a detour is actually usable
A line that appears to go around a closure is not enough. Evaluate the alternative against every criterion that can affect legality, navigation and safety.
| Question | What to verify | Warning sign |
|---|---|---|
| Is it legally open? | The current agency notice, field signs and any seasonal dates. | An undated map, an old trip report or a line shown without an open-status symbol. |
| Does it reach the same destination? | Named junctions and a continuous connection to your planned endpoint. | The line ends at a road, viewpoint or spur before the destination. |
| How much farther is it? | Mapped distance and elevation compared with your original plan. | Contours show a steep climb, a long traverse or a descent that your group did not plan for. |
| Who may use it? | Hiking, cycling, equestrian or motorized-use symbols and any text restrictions. | Your user type is absent, slashed out or excluded by a seasonal notice. |
| What is the surface and difficulty? | Trail classification, caution symbols and the manager’s description. | A route changes from a maintained path to an unmaintained or technical section. |
| When is it available? | Opening and closing dates, daylight limitations noted by the agency and current conditions. | The date on your map has passed or the detour is marked temporary without an end date. |
| Has the agency confirmed it? | A current closure map, signed arrows on the ground or a direct agency update. | Only an unofficial app track or user-created waypoint supports the route. |
What to do when signs, apps and maps disagree
Navigation apps are useful for orientation but can display old tracks, user uploads or routes that were legal before a closure. Treat a physical closure sign and the managing agency’s current instruction as more authoritative than an app’s uninterrupted line.

When a field sign says closed but the app shows open
Stop at the sign. Do not test the route to see whether the app is “right.” Record the trail name, date and any closure reason, then follow the signed detour or leave the area. Report a persistent discrepancy to the app provider only after you have complied with the agency’s restriction.
When an app shows a closure but the field route is signed open
Look for the map’s date and the agency’s current notice. A user report may lag behind a reopening, while a small temporary closure may not yet appear in the app. If no official source resolves the conflict, choose the conservative option and ask the land manager.
When a paper map conflicts with a sign
Check whether the paper map predates the sign, covers a different edition or uses a different agency’s data. Follow the local agency’s stated priority rule. In Colorado motorized areas, Stay The Trail says the current-year Motor Vehicle Use Map takes priority when it conflicts with signs; elsewhere, follow the rule published by the responsible agency rather than assuming Colorado’s practice applies.
Understanding red slashes and permitted-use symbols
A red slash through a permitted-use symbol indicates that the depicted use is closed. The slash may apply only to hikers, cyclists, equestrians or motor vehicles, so identify the underlying icon before acting. A trail can remain open to one user group while another is restricted.
Do not treat a red slash as a universal color code without reading the legend. Some maps use a red slash to mark a closure while other red marks identify hazards, roads or administrative boundaries. The legend, the sign text and the date together establish the meaning.

Before leaving for the trail
Closure status is volatile. A practical pre-departure check should happen as close to the outing as possible, especially after storms, fires, construction notices or wildlife alerts.
- Open the responsible park, forest, county or land-manager website or information channel and confirm the trail name and closure date.
- Download or print the current official map, including its legend and revision information.
- Identify at least one agency-confirmed alternative if the planned route is closed.
- Check that every member’s activity—walking, cycling, equestrian or motorized—is permitted on the route and detour.
- Compare the detour’s distance, elevation and difficulty with your group’s time, water, daylight and emergency margins.
- Carry a waterproof map. Official guidance favors current official maps and standardized symbols, while noting that store maps may be inaccurate about current trail conditions.
- Tell someone outside the group which route and detour you intend to use, and update that person if a closure changes your plan.
On-trail decision points and common mistakes
You encounter an unsigned social path around the barrier
Do not use it. An unofficial bypass may cross unstable ground, private property, habitat or the very area the closure is protecting. Return to the last confirmed junction and locate an official detour.
The detour arrow points toward a road
Follow the map far enough to determine whether the road section is part of the authorized route and whether pedestrians are permitted. Confirm crossings, shoulders and the next trail junction before committing your group.
The route beyond an “end of maintained trail” marker looks easy
Visual ease at the marker does not describe conditions farther on. Maintenance may end because of remote access, seasonal hazards or a management decision. Proceed only when the agency identifies the continuation as open for your use and you have the skills and equipment for an unmaintained route.
A closure appears after you have started
Stop at the boundary, reassess daylight and supplies, and use the signed alternative only if it is clearly open and within your group’s capability. If no suitable detour exists, turn back rather than improvising a bypass.

You see people beyond the barrier
Other visitors do not change the rule. They may be authorized workers, unaware of the closure or taking an illegal shortcut. Do not follow them.
How closures protect people and places
Respecting a closure reduces more than your own exposure to danger. Entering a prohibited segment can force rescuers into unstable terrain, disturb endangered wildlife, crush vegetation, worsen erosion and damage newly hardened trail work. Those impacts can lengthen the closure for everyone. Staying behind the boundary and using the designated route is part of the trail-management plan, not merely a courtesy.

- Turn back if no confirmed, suitable alternative exists.
Frequently Asked Questions
How do I know if a hiking trail is closed?
Read the exact wording on signs at the trailhead and junctions, look for a barricade or closure symbol, and confirm the trail’s status on the responsible agency’s current map or notice. Check the date and the permitted-user symbol, because a closure may be seasonal or limited to one activity.

A red slash through a permitted-use symbol means that use is closed. Read the map legend to identify the symbol and check whether the restriction applies to hikers, cyclists, equestrians or motor vehicles.
Can I go around a trail barricade?
No. A barricade marks the closure boundary. Do not move, climb or bypass it, and do not create a social path or cut a switchback. Use an agency-confirmed detour or turn around.
What is the difference between a closed trail and an unmaintained trail?
A closed trail is prohibited beyond the closure boundary. An “end of maintained trail” notice says routine maintenance ends; the continuation may be open only if the managing agency confirms it and you can safely handle more difficult navigation and terrain.
Which map is correct when the sign and app disagree?
Stop at the sign and follow the responsible land manager’s current instruction. Apps can contain old or user-submitted tracks. Apply any priority rule the local agency publishes; for Colorado motorized routes, the current-year Motor Vehicle Use Map takes priority when it conflicts with signs, according to Stay The Trail.
