Hanoi among Asia's 8 safest places for women to travel alone

"Though it is often overlooked when discussing the best solo trips for women, Vietnam's capital is generally a safe place for travelers," the Singapore-based magazine said.

It advised tourists to visit St. Joseph's Cathedral on Nha Chung Street in Hoan Kiem District, which was built during French colonial times and which adopted a Gothic Revival style to emulate the Notre Dame de Paris.

For those curious about Vietnam's history, the Temple of Literature, an 11th-century Confucian temple dedicated to scholars, and Ngoc Son Temple, which honors three important figures in the country's history, are both worth a visit.

Hanoi is also a budget-friendly destination for solo travelers, with a night's stay at a luxury hotel costing around US$150 and meals around $10 per day, according to Tripzilla.

Other Asian safe destinations included Seoul, Tokyo, Taipei, Singapore, Bangkok, Yogyakarta and Kuala Lumpur.
