Lincoln City is relatively secure for solo female travelers. The city is known for its friendly and welcoming inhabitants. However, it's always important to stay vigilant, especially during night hours or while visiting less crowded areas. Local police are typically very responsive and helpful. Highway 101 that goes through the city could get busy especially during the summer season, so pay extra attention while traversing. Overall, it's safe but keeping an eye on your surroundings is always a good practice.
