Well I'd suggest a forest instead but anyway depends how you get there :

• look up online how? there might be now a path on a server to your target destination
• disconnect phone in a pattern that's usually not how you use it? more surveillance
• public transport tracking, plate tracking until you leave the city
• rough estimation on your direction then follow up with drones tracking you, if it's 100m high it's hard to notice

... anyway, ending the paranoia comment ;)
