That’s where AI tools like PlaninGo.ai come in, making planning simple, safe, and tailored to you. This guide dives into the best cities for solo travelers in 2025, focusing on places that are safe, welcoming, and packed with experiences you’ll love.

From finding cozy cafes to connecting with other travelers, we’ve got you covered with practical tips and the best cities to explore.

What Makes Solo Travel Special

Solo travel is about freedom. You pick where to go, what to eat, and how long to stay. No compromises. It’s a chance to grow, push your comfort zone, and make memories that are yours alone. Social media is full of solo travel inspiration—think #solotravel with billions of views on TikTok. However, challenges like staying safe (a top concern for 65% of solo female travelers) or planning a trip that feels just right can deter people.

That’s where AI changes the game. Tools like PlaninGo.ai act like a travel buddy in your pocket, suggesting safe places to stay, fun things to do, and even group activities to meet others. They take the stress out of planning so you can focus on the adventure. Let’s explore the top cities that make solo travel a breeze in 2025.

The Best Cities for Solo Travelers in 2025

These cities are carefully selected for their safety, ease of navigation, and solo-friendly atmosphere. Each one offers something unique, from vibrant city life to serene natural surroundings. Plus, we’ll share how PlaninGo.ai can make your trip even better with personalized, AI-powered planning.

1. Tokyo, Japan

Why It’s Great:
Tokyo is a dream for solo travelers. It’s one of the safest major cities in the world, boasting a low crime rate and highly reliable trains. You can wander through bustling Shibuya, find peace at Meiji Shrine, or grab sushi at a solo-friendly conveyor belt restaurant. The mix of modern tech and ancient culture feels like stepping into a sci-fi movie and a history book at the same time.

How AI Helps:
PlaninGo.ai makes Tokyo less overwhelming by mapping out your day—think navigating the subway or finding a cozy izakaya for dinner. It can suggest safe and affordable hotels in areas like Asakusa and even warn you about crowded spots in real-time. For female travelers, AI can recommend accommodations that prioritize women's safety and security.

Safety Tips:

Keep a portable Wi-Fi device for constant navigation.

Share your plans with a friend using PlaninGo.ai’s itinerary-sharing tool.

Blend in by dressing modestly and keeping valuables low-key.

Ca n’t-Miss Moments:

Stroll through Tsukiji Market for fresh sushi.

Geek out in Akihabara’s anime and tech shops.

Take a quick train to Kyoto for temples and history.

Why It Stands Out:
Tokyo’s mix of safety and endless things to do makes it an ideal destination for first-time solo travelers. You’ll feel secure yet never bored, with AI helping you discover hidden gems like quiet tea houses or quirky themed cafes.

2. Reykjavik, Iceland

Why It’s Great:
Reykjavik feels like a small town with big adventures. Iceland is one of the safest countries, and its capital is super walkable. Locals are friendly, and the city’s cozy vibe makes it easy to feel at home. Plus, you’re steps away from jaw-dropping nature—think Northern Lights or geothermal pools.

How AI Helps:
PlaninGo.ai tailors your trip around Iceland’s tricky weather, suggesting the best times for outdoor adventures like the Golden Circle. It can book you into vetted group tours, so you’re never exploring remote areas alone. AI also finds central hotels, keeping you close to the action.

Safety Tips:

Check weather updates through AI tools before heading out.

Stick to central areas for easy access to shops and cafes.

Join group tours for far-off spots like waterfalls or glaciers.

Ca n’t-Miss Moments:

Relax in the Blue Lagoon’s warm waters.

Hunt for the Northern Lights with a guide.

Climb Hallgrímskirkja for a view of the city’s colorful rooftops.

Why It Stands Out:
Reykjavik’s small size and safe streets make it an ideal destination for solo travelers seeking a peaceful and natural experience. AI ensures you’re prepared for Iceland’s unpredictable weather, letting you focus on the magic of the moment.

3. Barcelona, Spain

Why It’s Great:
Barcelona’s sunny vibe, colorful architecture, and lively streets make it a solo traveler’s playground. Spain ranks high for safety, especially for women, and the city’s tourist-friendly buses and English-speaking locals make it easy to get around. From Gaudí’s whimsical buildings to beachside strolls, there’s something for everyone.

How AI Helps:
PlaninGo.ai crafts a Barcelona itinerary featuring safe neighborhoods like Eixample and fun activities, such as tapas tours. It can connect you with social events, such as meetups for young travelers, so you’re never alone. AI also suggests reliable taxis or buses for late-night outings.

Safety Tips:

Stay in well-lit areas, such as La Rambla, after dark.

Utilize AI to discover reliable transportation options.

Keep a close eye on your belongings in crowded areas.

Ca n’t-Miss Moments:

Marvel at Sagrada Familia’s wild architecture.

Wander Park Güell’s mosaic-filled paths.

Join a food tour to experience local flavors and connect with fellow food enthusiasts.

Why It Stands Out:
Barcelona’s welcoming energy and solo-friendly activities make it a top pick. AI helps you balance sightseeing with social moments, ensuring you feel connected without losing your independence.

4. Copenhagen, Denmark

Why It’s Great:
Copenhagen is a solo traveler’s dream—safe, bike-friendly, and full of charm. Its compact size means you can explore Nyhavn’s colorful waterfront or Tivoli Gardens’ magic without feeling lost. Danes are warm, and the city’s laid-back vibe makes it easy to relax.

How AI Helps:
PlaninGo.ai maps out bike routes and suggests solo-friendly cafes or museums. It can recommend boutique hotels with communal spaces, perfect for meeting other travelers. AI also keeps your itinerary flexible, so you can pivot if plans change.

Safety Tips:

Stick to bike lanes for safe exploring.

Share your itinerary with someone back home.

Be cautious of your belongings in busy tourist areas.

Ca n’t-Miss Moments:

Snap a photo at the Little Mermaid statue.

Ride roller coasters at Tivoli Gardens.

Bike to Christianshavn for canal-side views.

Why It Stands Out:
Copenhagen’s safety and bikeable streets make it perfect for solo explorers who want a mix of culture and ease. AI ensures you hit all the highlights without feeling rushed.

5. Queenstown, New Zealand

Why It’s Great:
Queenstown is an adventure lover’s paradise. Surrounded by mountains and lakes, it’s perfect for solo travelers who crave thrills like bungee jumping or hiking. New Zealand’s friendly culture and low crime rate make it a safe bet for solo adventures.

How AI Helps:
PlaninGo.ai books you into trusted adventure tours, like jet boating or skiing, and suggests safe trails for solo hikes. It also finds budget-friendly hostels with social vibes, so you can connect with other travelers.

Safety Tips:

Follow guides’ advice for adventure activities.

Check trail conditions with AI before heading out on a hike.

Let someone know your plans for remote outings.

Ca n’t-Miss Moments:

Bungee jump at Kawarau Bridge.

Hike Ben Lomond for epic views.

Cruise Lake Wakatipu for a relaxing day.

Why It Stands Out:
Queenstown’s mix of adrenaline and natural beauty is unbeatable for solo travelers who love action. AI keeps you safe and organized, so you can focus on the thrill.

6. Chiang Mai, Thailand

Why It’s Great:
Chiang Mai is a haven for budget-conscious solo travelers. Its temples, night markets, and affordable hostels create a welcoming vibe. The city’s backpacker scene makes it easy to meet others, and its slower pace feels less hectic than Bangkok.

How AI Helps:
PlaninGo.ai balances temple visits with relaxing activities like Thai cooking classes. It suggests vetted hostels with community events, ensuring you feel a sense of connection. AI also recommends safe tuk-tuk drivers for easy transport.

Safety Tips:

Choose well-reviewed transport options via AI.

Avoid drinking too much when alone.

Stay in hostels with strong safety ratings.

Ca n’t-Miss Moments:

Visit Wat Phra That Doi Suthep for stunning views.

Shop and eat at the Night Bazaar.

Learn to cook Thai food in a group class.

Why It Stands Out:
Chiang Mai’s affordability and community feel make it perfect for solo travelers seeking culture and connection. AI helps you avoid tourist traps and find authentic experiences.

7. Vancouver, Canada

Why It’s Great:
Vancouver blends city life with nature, offering solo travelers the best of both worlds. Its safe public transit and diverse neighborhoods, like Gastown or Kitsilano, make it easy to explore. Nearby mountains and beaches add an extra layer of adventure to your trip.

How AI Helps:
PlaninGo.ai combines city highlights with day trips, such as hiking in Whistler. It suggests safe neighborhoods for accommodations and group tours, offering a social vibe. AI also keeps you updated on transit schedules for stress-free travel.

Safety Tips:

Use buses or SkyTrain for safe travel.

Share your plans with a friend via AI tools.

Stay alert in busy areas, such as Granville Street, especially at night.

Ca n’t-Miss Moments:

Bike Stanley Park’s scenic seawall.

Explore Granville Island’s food market.

Visit Capilano Suspension Bridge for a thrill.

Why It Stands Out:
Vancouver’s safety and natural beauty make it a gem for solo travelers. AI helps you balance urban exploration with outdoor escapes, creating a trip that feels just right.
