Write a Trip Plan Someone Can Use

A trip plan is a short, practical note that helps someone outside your group understand where you intend to go and when to expect you back. It is not a guarantee that every detail will unfold as expected. It gives your contact a clear starting point if you do not return or check in on time. Before leaving, agree on who will hold the plan, how you will check in, and what that person should do if they cannot reach you. Local emergency procedures differ, so use the guidance of the area you are visiting.

Choose a reliable contact

Select someone who is not joining the trip, understands the plan, and will be available during the time you are outdoors. Tell them directly that they are your check-in contact and confirm they agree. Avoid sending a note to several people without deciding who is responsible; that can leave everyone assuming someone else will act. If the trip is long, remote, or involves multiple days, arrange a contact who can follow the schedule and knows how to reach local authorities.

Give the contact a realistic return time and a clear overdue threshold. For example, you might say that you expect to check in by a certain time and that if you have not done so after an agreed interval, they should first try your group and then follow the local emergency process. Do not use a vague instruction such as “call if worried.” The contact needs to know when to act and what information to provide. Never ask them to search for you themselves if they are not trained and equipped to do so.

Include the details that make the route identifiable

Write the destination, trailhead, route name, direction of travel, planned stops, and expected return. If the route is a loop or out-and-back, say so. For a point-to-point route, include the exit point and how your group will travel between trailheads. Identify the map or official route page you used, and note a backup destination. Include permit or reservation details if they affect where and when you may enter. A route name alone may be insufficient when several trails share similar names.

Add departure and return times, vehicle location or transport plan, and a description of the group that would help someone identify you. Share only the details that are useful for safety. You do not need to disclose unrelated personal information. For an overnight trip, include each planned campsite or stop, the nights you expect to be there, and the route between them. Explain what part of the itinerary is fixed and what may change if conditions require an alternate plan.

Include a practical summary of your equipment and communication plan. Note whether you expect phone coverage, whether you will use a satellite communicator or other device, and how the contact should interpret a missed message. Do not imply that an app or location-sharing feature will work in every place. If your group carries an emergency communication device, explain who has it and how it is intended to be used. The contact should understand that the device complements a plan; it does not replace one.

Make the plan easy to use

Use plain language and organize the note so someone can scan it quickly. Put the route, return deadline, and contact instructions near the top. Spell out place names and avoid abbreviations that only your group understands. A simple printed sheet, calendar entry, or message can work. If you use an online trip-plan tool, make sure the person can actually open the information and knows where to find it. A link that requires a sign-in they do not have is not a useful handoff.

Share the plan before departure and confirm that your contact has received it. If the route, start time, or return estimate changes, send an update while you still have a reliable connection. Tell the contact if you switch to the backup plan, and check in when the trip is over. If you cannot send an update, follow the pre-agreed plan as closely as possible. The outside contact should not have to guess whether your silence means a change of plan, a dead battery, or a problem.

Build a backup into the itinerary

Choose a backup that matches the reason you may need to change plans. It might be a shorter route, a lower elevation option, an alternate campsite, or postponing the outing. Record where the backup begins and ends and how you will return to transport. Set a latest start time and a turnaround time so the group does not have to make a high-pressure decision when tired or rushed. If a closure or hazard affects the original route, verify that the backup is outside the same affected area.

Discuss decision points with the group before leaving. Agree that anyone can ask to pause, turn around, or use the backup without being blamed. A trip plan is useful only if the group is willing to adjust it. Weather, trail conditions, injury, late transport, fatigue, or a missing essential can make the original itinerary unsuitable. The choice to change a route is part of good planning, not evidence that the plan failed.
