How to Leave a Trip Plan Before You Hike

To leave a trip plan, tell a reliable person your exact route, planned camps, start and end dates, vehicle description, who's with you, and a specific overdue time, after which they should call for help. This single habit is the biggest factor in how fast search and rescue can find you if something goes wrong, and it costs nothing but a few minutes before you leave.
A vague 'I'll be hiking around the mountains this weekend' text tells rescuers almost nothing. A real trip plan gives them a starting point, a search area, and a deadline.
What a trip plan actually needs to contain
- Exact route: trailhead, trail names or route, direction of travel, and any planned side trips or alternates
- Planned camps: where you intend to sleep each night, ideally with mileage between them
- Dates and times: start date, planned finish date, and your expected return time on the last day
- Vehicle description: make, model, color, and license plate, and where it will be parked
- Party details: names and number of people, plus any relevant medical conditions worth knowing about
- A specific overdue time: the exact point at which your contact should treat you as overdue and call for help, not a vague 'if you don't hear from me'
The overdue time is the detail people skip most often, and it's the one that actually triggers a response. 'Call the ranger station if I haven't texted you by 8 p.m. Sunday' is something your contact can act on; 'I'll probably be back Sunday' isn't.
Who to leave it with, and how
Pick someone reliable who will actually notice if you don't check in, not just whoever you happen to text last. Ideally give the same information to two people in case one is unreachable. Ranger stations or permit offices sometimes collect trip plan details as part of a permit, which is useful but isn't a substitute for a personal contact who's actively watching for your check-in.
Make the plan specific enough that your contact could hand it directly to search and rescue with no clarification needed. If your route or dates change after you've already left the plan, that's a real gap, so treat the plan as fixed once you're on trail unless you have a way to update your contact.
The check-in protocol
Agree on exactly what counts as checking in (a text, a call, a specific satellite messenger message) and exactly when it needs to happen. Build in a little buffer for normal trail delays, but keep the overdue time firm rather than open-ended, an overdue time that keeps sliding defeats the purpose.
Tell your contact explicitly what to do if you don't check in: who to call first (usually the local sheriff's office or the land management agency for the area, not 911 directly in most regions, though this varies), and that they should share your full trip plan with them immediately rather than waiting to see if you turn up.
Why this shortens search and rescue time
Search and rescue operations start by defining a search area, and every detail in your trip plan narrows that area dramatically. A known trailhead, direction of travel, and planned camps let searchers work outward from your most likely location instead of searching an entire mountain range. This is the same reason the STOP protocol tells lost hikers to stay near their last known point rather than wander, it keeps you inside the area your trip plan already defined.
A digital option works well here too: RidgeSync's public share links show your planned route and camps on a map, so instead of describing your route in a text message, you can send a link your contact can actually look at and reference if they need to call for help.
Frequently asked questions
What should a hiking trip plan include?
Your exact route, planned camps, start and end dates, vehicle description, who's with you, and a specific overdue time after which your contact should call for help. Vague plans give rescuers almost nothing to work with.
Who should I leave my trip plan with?
A reliable person who will actually notice if you don't check in, ideally two people in case one is unreachable. A permit office trip plan is useful but isn't a substitute for a personal contact actively watching for you.
What is an overdue time and why does it matter?
It's the specific time your contact should treat you as overdue and call for help, rather than a vague sense of when you'll be back. It's the detail that actually triggers a rescue response, so make it exact.
How does a trip plan help search and rescue?
It narrows the search area to your known trailhead, route, direction of travel, and planned camps, letting rescuers work outward from your most likely location instead of searching a much larger area blind.
Can I share a digital trip plan instead of writing it out?
Yes. A share link showing your planned route and camps, like the ones RidgeSync generates, lets your contact see exactly where you intended to be, which is easier to reference than a text description if they need to call for help.
