Vienna, Rio, Ecuador and Mexico are all top destinations for those planning solo trips abroad, according to travel website IgoUgo.com.
The Austrian capital was named as the top travel spot for lone travellers due to its "mind-boggling array of concerts and operas".
Florence was in the number three position, with one contributor to the list calling it the perfect size city for a solo woman to conquer.
The historic Italian city is the capital of Tuscany and has around half a million residents. It is located in the famous Chianti wine region, a top destination for wine lovers the world over.
Ayampe in Ecuador was also noted for its tranquil beach resorts, offering both isolation and a "chance to mingle with the locals and really relax".
Those looking for a little adventure are advised to head to Puerto Vallerta, Mexico, where a great number of lone travellers congregate, away from the honeymooning couples in places like Cancun, the website asserts.
