I wanted a place with great weather, interesting culture, fantastic food and friendly people — and with plenty to see in a week.

So I picked Vietnam, traveling from Ho Chi Minh City through the Mekong Delta area and on to Phu Quoc, an island in the Gulf of Thailand.

The next day, I headed out for an 8 a.m. walking tour organized via GuruWalk, which matches local guides with visitors. A group of about 12 met our guide, Thanh, by a statue of former Vietnam president Ho Chi Minh at the north end of Nguyen Hue, a striking boulevard in the central district of Ben Nghe.

Thanh pointed toward a sign on the top of the nearby Rex Hotel that read: “Five o’clock follies,” referring to the U.S. military briefings given to journalists at the hotel during the Vietnam War, which were notoriously unreliable. Its rooftop is now home to a garden bar, which I later found pleasant for an evening drink with a view.

France began its colonization of Vietnam in 1858 and a block or so away from the Rex Hotel our tour stopped opposite the late 19th-century Saigon Opera House, designed by French architect Eugene Ferret. It’s also a backdrop that proved popular for photographs — I saw two bridal couples swiftly dodge between moving traffic to pose by its steps.

Further along the street Thanh showed us the charming Central Post Office, which is also French-designed and largely unchanged since the 1880s. From there, I sent a postcard back home to the U.K. Close by is the twin-spired Notre Dame Cathedral, a red brick building sitting at one end of a square where a statue of the Virgin Mary stands.

Reminders of the 1955-1975 Vietnam War — known by many Vietnamese as the American War — are all around the city, including an army tank on the grounds of the Independence Palace that marked the end of the conflict.

North of the palace is the War Remnants Museum, where visitors can see “The Terror of War,” the photograph that became known as “Napalm Girl,” an image of Phan Thi Kim Phuc running naked down the street after a 1972 attack by the South Vietnamese air force.

For upscale accommodations, residents I spoke to recommended the five-star Caravelle Hotel, opened in the 1950s by French entrepreneurs Antonin Emery and Marius Mallein, a favorite of American journalists during the Vietnam War. Its rooftop bar, Saigon Saigon, has live bands most nights and guests can choose from three restaurants.

I stayed at the mid-range Silverland Jolie, which is within walking distance from Nguyen Hue. It has a small plunge pool and cocktail bar on its rooftop, plus attentive service.

Although I only stayed a short time, I fell in love with Ho Chi Minh City’s grand architecture, history and general buzz. The city is undoubtedly hectic, but I found the people super friendly — one time, a restaurant employee went out of his way to help me cross the road. The traffic may be eased by the city’s new metro system, set to open later this year.

Southwest of Ho Chi Minh City lies the Mekong Delta, a region of rice paddies, rivers and floating markets. There are many ways to see the area, from homestays to companies that organize more luxurious trips there.

I joined a two-night sightseeing bus and boat trip with Vietnam Adventure Tours, which was well organized and offers numerous excursions and overnight stays in the area. Our first stop was the town of My Tho to see the Vinh Trang Pagoda built in 1849. After seeing monks at prayer, several schoolchildren approached me, asking to practice their English.

Then we took to the river itself, where guides rowed our group in small wooden boats down a narrow channel lined with palms, before stopping at Con Quy island to see how coconut candy is produced.

Even though they can be crowded with tourists, the floating markets were a highlight of the Mekong Delta for me, with cone-hatted merchants selling everything from fruit to haircuts from their boats — an experience best seen early in the morning.

Our tour visited Cai Be market, just outside the city of Can Tho, where we tasted freshly cut pineapple with chili salt (surprisingly good) and strong Vietnamese coffee from a seller who moored her boat next to ours.

Tour operators in the Mekong Delta are plentiful, but some trips only run if there’s a minimum number of participants, which can be tricky for a solo traveler. Mekong Eyes is a well-reviewed operator that runs small river cruises on traditional rice barges in southern Vietnam and on to Phnom Penh in Cambodia.

After a hectic few days of traveling, I booked myself into Cassia Cottage, a beachside resort set in pretty gardens on tropical Phu Quoc Island, which is a short flight from Can Tho or Ho Chi Minh City. There, I lazed on beaches lined with palm trees, wandering into the sea when it became too hot or relaxing by one of three pools with a cucumber martini.

The resort is owned by Mark Barnett, a U.S. expat who spent more than two decades as a major exporter of cassia — or cinnamon — from Vietnam before selling his company to a Japanese firm. I often saw him speaking to guests at mealtimes.

The Spice House, the resort’s excellent restaurant, serves Italian food, alongside Vietnamese dishes like seafood spring rolls and pho.

Staying on a tropical island alone might not appeal to everyone, but I loved being able to choose exactly what I wanted to do and when — whether it was having a massage at Cassia’s small seaside pavilion or heading out to sea on a boat trip to explore more of the island.
