Traveling solo as a woman can be one of the most empowering experiences — but it’s also something I approach with intention, preparation, and a healthy dose of systems thinking. As an engineer, I’ve learned to analyze risk, optimize for efficiency, and prototype solutions for everyday challenges — and I apply that same mindset to the way I travel.
Here are my top 10 safety hacks every solo traveler (especially my fellow STEMinists 💻💪) should know:
1. Have a Redundant Itinerary System
Don’t just share your travel details — systematize it. I create a quick travel PDF with flight numbers, hotel addresses, emergency contacts, and key reservation info and send it to a family member and store it offline on my phone and in my email.
✅ Bonus Tip: Use a cloud-based tool like Notion or Google Docs for real-time updates.
2. Run a “What-If” Risk Simulation
Before every trip, I literally ask:
- What if my phone dies?
- What if I lose my passport?
- What if I miss my train?
Then I build a mini response plan for each. This helps me feel more confident and calm before anything goes wrong.
3. Carry a Doorstop Alarm or Portable Lock
This tiny, engineer-approved gadget has saved my peace of mind in budget hotels and Airbnb stays. A doorstop alarm wedges under the door and sounds off if someone tries to enter. Lightweight and cheap — high ROI!

4. Use Dual Wallet Systems
Keep a decoy wallet with expired cards and a small amount of cash, and hide your real valuables elsewhere (I recommend a hidden pocket inside your bra or waistband).

✅ Bonus Tip: I always have my cross-body when I am traveling. However, I always have the strap hidden under layers; This reduces the chance of my purse straps being cut.
5. Fake a Phone Call When Necessary
If someone is making you uncomfortable, pretend to take a call from a friend or partner. I even pre-recorded a voice memo of “Hey babe, I’m walking back now” to play in a pinch. Judge me — but it works.
6. Reverse-Engineer Your Transit Routes
When booking lodging, I always check how I’ll get there after dark. I trace the route both on Google Maps and public transport apps and look up neighborhood safety reviews.
🔍 Engineer’s mindset: Look at time of day, lighting, walkability, and backup ride options.
7. Choose Lodging with 24/7 Staff
When solo, I opt for places with front desks or on-site hosts over self check-in. It’s not just for comfort — it’s a safety redundancy. If something goes wrong, you’ll want someone available.
8. Avoid Being Predictable
Change up your walking routes when staying in the same city for more than 2 days. I vary my breakfast spot, cross streets randomly, and don’t always post my location in real time.
9. Use Airplane Mode + Maps.me Offline Navigation
Download the Maps.me app for offline navigation. It’s more accurate than some GPS tools and doesn’t need data or WiFi — meaning you’re not relying on sketchy public signals in unfamiliar places.
10. Practice Boundary Scripts Before You Travel
I script and rehearse phrases like:
- “I’m meeting someone in five minutes.”
- “No, thank you.”
- “Please stop. That’s not okay.”
It sounds silly, but rehearsing helps your nervous system respond more clearly in real moments.
Final Thought
Solo travel isn’t about fear — it’s about freedom with foresight. With a bit of strategy and self-trust, it’s one of the most powerful ways to reconnect with yourself and the world around you.
