Agencies revealed that registrations for summer tours have increased by nearly 80 percent compared to those in other seasons, with a focus on sea tours.

Vietravel, one of the largest travel companies in Vietnam, has opened more than 20 new routes to serve the increasing demand of holidaymakers.

It introduced new tours to the sea and island paradises of Co To Island in northern Quang Ninh province, Ly Son island in central Quang Ngai, and Tuy Hoa beach in central Phu Yen province, whose natural beauty remains untouched.

The company is also offering discounts up to 57 percent on several tours to the Mekong Delta and central regions, as well as applying preferential prices in outbound tours to the US and the UK.

The company expects to serve 180,000 tourists during this summer, up 30 percent from the same period last year.

Along with new tours to beautiful beaches, Vietrantour and HanoiRedtours have also strengthened cooperation with airlines, including national flag carrier Vietnam Airlines and Jetstar Pacific, to diversify their products.
