Understanding Trail Access Information

Trail access information describes conditions an organization measured on a trail or an assessed part of it. Use these details alongside current alerts and the information you need for your own visit.

Find the Assessment

1. Open a trail from the map, search, or a saved place.
2. Tap Info.
3. Find Trail Access. On Android, it appears as Trail Access Information under Visitor Information; tap it to expand.
4. Read which trail, section, or trail segment was assessed.
5. Check the assessment date, source, and any coverage warning before using the measurements. They appear first, ahead of the measurements.

Availability varies by trail and organization. When no assessment is recorded or saved on your device, the trail access section does not appear. A missing assessment does not mean a trail is suitable or unsuitable for you.

Understand the Measurements

• Assessed Length describes the distance covered by the assessment. It can be shorter than the full trail.
• Typical Grade and Maximum Grade describe the slope along the trail. A short, steep pitch can differ substantially from the typical slope.
• Typical Cross Slope and Maximum Cross Slope describe the slope across the trail.
• Typical Tread Width and Minimum Tread Width describe the recorded clear tread width, in centimeters or inches. Obstacles can create additional limitations.

Expand Assessment Details for surfaces, obstacles, the assessment method, source units, reporting limits, and any profile references.

• Surface identifies recorded surfaces and may include how much of the trail each covers, along with quality, firmness, or stability.

Measurements follow your unit preferences where applicable. Source Units explains the original units when supplied. Recorded obstacle magnitudes retain their supplied units.

Not Recorded means a measurement is unavailable. A value of zero is a recorded zero; it is different from missing information. A partially completed assessment can still contain useful measurements.

Read Obstacles and Reporting Limits Together

Recorded obstacles show their type and size first, then the supplied location, the distance from the assessment start, and notes. A profile or official reference may provide more detail.

Check Reporting Limits and the assessment method. An assessment may record obstacles only above a particular size, or exclude temporary obstacles. A statement that no obstacles were observed or reported applies only within those reporting limits and the assessed extent. It is not a guarantee that nothing will obstruct your visit.

Check the Assessed Extent and Date

Each assessment names the part of the route it covers: the full trail, a section, or a trail segment. An assessment of a section or segment applies only to that part of the route. Do not apply its measurements to the remainder of the trail or a different outing.

A coverage warning means the route changed or the relationship between the recorded assessment and the current route needs review. The values still describe their original assessed extent.

Tap View Assessed Extent to see the recorded assessment on a map. The highlighted line shows the original assessed extent, which can differ from the current trail. On iOS, the map opens in its own screen; expand Extent Description below it for the supplied description and the start and end coordinates of each mapped line. On Android, the map appears in place; tap Hide Map to close it.

The assessment date tells you when conditions were measured. Conditions may change afterward. Current alerts and closures remain relevant even when an assessment is available.

Distinguish Statements From Measurements

An Organization Statement is attributed to its source and original assessed extent. It is separate from the physical measurements. Recreational difficulty describes a different aspect of the route and is not calculated from these measurements.

Trail access information does not certify that a route meets an accessibility law or that it will meet every visitor’s needs. Contact the publishing organization when you need information that is missing or unclear.

Use Saved Information Carefully

Saved or downloaded assessments remain available where supported. A line above the trail access information shows when the location's information was checked. If a refresh fails, the line says so and shows when the saved information was checked; on Android, tap Try Again to retry. The assessment date remains the date the trail was measured.

If no trail access information appears, it may not be recorded, or it may not be saved on your device. Connect to check again. While offline, check the displayed dates and do not treat saved information as a live check of alerts, closures, or trail conditions.

Report a Change

Use the organization’s contact information on the place page to ask about missing information or report conditions that differ from the assessment. Include the trail or section and what changed. For urgent hazards, follow the organization’s posted safety guidance.
