Bali in Indonesia, known locally as 'the Island of the Gods', is one of the best choices if you love the thought of sun-soaked beaches, volcano trekking, and scenic countryside with terraced rice fields.

Singapore, a clean and modern city, is one of the most family-friendly destinations in Southeast Asia. It is favored by families due to its arts, fashion, food, culture, and big-name events.

Luang Prabang in Laos and Bagan in Myanmar are favored choices for couples who love charming romantic old towns, fascinatingly-designed temples, and Buddhist culture.

1) Thailand: Temples, Elephants, Beaches

Thailand is the travel hub of Southeast Asia. Within its borders are sunny beaches, ornate temples, and lush national parks and jungles. There is so much to do in Thailand, whether you want to explore and have fun with kids, or enjoy romantic moments with your significant other.

Whether traveling as a family or couple, meeting elephants in a jungle, taking a Thai cooking class, and exploring Bangkok's classic temples, amazing food, and floating markets are all must-dos.

For your choice of islands, Koh Samui is more recommended for couples due to its quiet and romantic vibe. While Phuket is more suitable for families with kids, as it's known for its abundant water sports and activities.

Yi Peng Festival in Chiang Mai is definitely not to be missed, where you can see the romantic scene of countless flying lanterns released into the sky.

For a special experience, you could spend an amazing evening with your spouse/partner (and kids) in Kanchanaburi's floating house or a tree house in Khao Sok National Park.

2) Vietnam: Outdoor Adventures, Scenic Wonders, Countryside Relaxation

Hanoi and Hoi An represent traditional Vietnam, Halong Bay represents scenic Vietnam, while Ho Chi Minh epitomizes modern Vietnam with many great museums.

Hanoi is a must because of the incredible, buzzing Old Quarter, displaying history at every turn.

A luxury Halong Bay cruise is recommended for both couples and families. Spend 1–2 nights boating around the numerous islands and admiring the karst formations rising from the sea.

There are many exciting activities in Halong Bay, like kayaking, swimming, and cycling. If your plan to celebrate a big event, we can help arrange a more private cruise only for you as a couple or just your family members.

Ho Chi Minh City is Vietnam's most fashionable city, known for its amazing food, skyscrapers, and sleepless bars. It is also a must-visit for everyone with an interest in history due to its many museums!

After 2–3 hours' driving from Ho Chi Minh, you can transit from city's dynamism to the primitive simplicity of the Mekong Delta. Get to see how the local Vietnamese keep their traditional lifestyle: trading in the floating markets, making sugar in a family workshop, living in a boat house, etc.

3) Cambodia: Culture Immersion

Angkor Wat, without a doubt, is the biggest attraction in Cambodia. It is a place where children can experience the culture's charms as well as adults. It was once the capital of the Khmer kingdom — the most powerful in Southeast Asian history. There, you can walk through the ruins of once-glorious buildings and discover their history.

For those who like all the fun close together, Bali is a one-stop enjoyment island with incredible beach resorts, beautiful beaches, water sports, yoga, a wild nightlife, friendly people, and enough shops to shop until you drop.

It is one of the most popular destinations in SE Asia, and once you get there you will instantly understand why.

There you can embrace your loved one(s) in a cruise under the sunset, relax at a spa surrounded by nature, cycle through the rice terraces, take cooking classes, go on a volcano sunrise trek...

Luang Prabang is its most popular destination as a result of the many beautiful historical sites, the unique surrounding scenery, the pure alms-giving ceremony, as well as its elephant sanctuary with well-preserved habitat.

Tour recommendation: 14-Day Vietnam, Cambodia, and Laos Tour

7) Myanmar: A Romantic Way to See Temple Relics

There's nothing more romantic in Myanmar than taking a hot air balloon ride in Bagan over 2,000 pagodas and temples to watch the sunrise from the sky.

Bagan is enthusiastically loved by photographers, couples, and people who are sympathetic to Buddhism.

Visit Bagan before it's overwhelmed by tourists!

3. Consider the Best Times to Travel

Lying within the tropics with southern areas very close to the equator, most of Southeast Asia is warm all year round.

• Generally speaking, the best time to visit most places in Southeast Asia is from November to February when the weather is dry (driest) and warm (on average). One of the busiest times is around Christmas and New Year. Hotels in popular cities/islands and flights between popular destinations are likely to be sold out in advance. Be sure to plan and make reservations in advance.
• Wet-season monsoon rains fall from June to October in most SE Asian countries (Thailand, Vietnam, Cambodia, Laos, and Myanmar). The brief, intense rain showers during the wet season are unlikely to disrupt your plans.
• April to May are the hottest months with daytime temperatures reaching 37–40°C (99–104°F).

However, Indonesia (Bali) and Singapore are exceptions.

• The dry seasons in these two countries are from April to September.
• The rainy season (usually downpours in the afternoon) falls from October to March.

The rainy season and the hottest months usually reward you with less crowding and the best deals for flights and hotels. Take your outdoor activities mainly in the morning time during the rainy season.

4. Plan Your Budget

Traveling in Southeast Asia is way cheaper than in Europe and North America. A private tour in this region becomes an affordable indulgence, promising a luxurious experience without breaking the bank.

Hotels here won't break the bank. A 3-star hotel in Thailand is around 50-70 USD, and a 4-star one is 80-100 USD. Even luxury hotels cost as much as budget ones in the UK or US. You can go fancy or save big by staying in a hostel.

Eating is super affordable, thanks to awesome street food. Street vendors and small restaurants are cheap, and even fancy international meals in good restaurants won't cost more than a regular dinner in the UK or US. Imagine paying just 10 bucks for lunch and 20 to 50 USD for a nice dinner.

Activities are a steal too. Entry fees to temples and tourist spots are generally low, and adventurous experiences such as elephant trekking, snorkeling, and boat trips seldom exceed 20 USD.

Booking a trip to Thailand with Asia Highlights is excellent value for money!
