Vietnam Off the Radar:
Secret Islands, Mountain Retreats, and a Wild, Crowd-Free Coastline Automatic translate

The standard resorts of the south and center of the country have long been living by their own inertia — the coastlines are lined with high-rise hotels, the wide beaches welcome tens of thousands of people daily, and the tourist service increasingly resembles a conveyor belt. Experienced travelers are reacting predictably: they’re moving off the beaten path to places where nature hasn’t yet become a backdrop.

The hotel industry is gradually adapting to this demand. Small, isolated eco-resorts are being built with minimal environmental impact — bamboo and local stone instead of concrete, autonomous solar panels instead of diesel generators, preserved wild vegetation instead of manicured lawns. Tourists consider the extra hours of travel worthwhile: what unfolds at the other end of the serpentine road is incomparable to a package tour.

The Asian region is slowly but surely transitioning to a sustainable tourism model. Government agencies are restricting permits for large-scale capital development in protected forest and coastal areas. Water quality in freshwater bodies is improving, and noise pollution levels are declining. Nature is getting a real chance to recover after decades of commercial exploitation.

Lan Ha Bay: A Quiet Alternative to Ha Long

Ha Long Bay is one of Vietnam’s most famous natural landmarks and also one of its most congested. Hundreds of diesel-powered pleasure boats ply its waters daily, creating a floating metropolis on the horizon. Further south, Lan Ha Bay boasts the same vertical limestone karst islands, but without the traffic — it’s quiet, almost deserted, and has exceptionally clear water year-round.

For an overnight stay, a wooden boat with a spacious open deck is rented here. Sometimes small themed agencies can help find a suitable vessel — for example, those specializing in Vietnam for 99 euros often offer such unique options alongside standard packages. The floating base is anchored in a sheltered bay, and for the next few hours, the horizon consists solely of water, rocks, and sky.

Tourists rent lightweight fiberglass boats and navigate through narrow stone tunnels to hidden internal lagoons. Inside the caves, the water is completely still — no wind penetrates. Sunlight filters through vertical cracks in the stone vaults, illuminating the stalactites below. Scattered along the shore are narrow, wild beaches several dozen meters wide, accessible only by sea. A few kilometers to the east are the floating wooden houses of fishermen who have been breeding bivalve mollusks on underwater farms for generations.

Pu Luong Nature Reserve: Rice Terraces Without the Fuss

In the popular imagination, the northern mountainous regions are reduced to Sapa. The problem is that Sapa itself has long ceased to be a mountain village — souvenir stalls, multi-story concrete buildings, and endless organized tour groups have supplanted what people originally came for. Pu Luong National Park, located southwest of Hanoi, offers a similar landscape — steep slopes, stepped rice fields, dense pine forests — but without the tourist trappings.

The gravity irrigation system in Pu Luong is powered by bamboo water wheels up to 5 meters in diameter, which continuously lift water from the rivers to the upper agricultural levels. This centuries-old system still operates without electricity.

The drive from Hanoi takes about four and a half hours along a serpentine mountain road. A few guesthouses on stilts are carefully integrated into the sloping terrain, without disturbing it. Some have infinity pools with direct views of the river valley, heated by the sun without electric heaters. Evening temperatures drop to around 18 degrees Celsius — the mountain climate is noticeably different from the coastal one. Trekking routes to the waterfalls are well-marked, with elevation changes ranging from 100 to 800 meters, and the dense canopy of trees provides shade almost all day.

Con Dao Archipelago: A Reluctant Nature Reserve

The Con Dao group of islands, far out in the South China Sea, owes its preservation not to environmental policy — at least not initially. It owes its long-standing isolation from transport and a peculiar past: in the 20th century, it housed state-run prisons. Today, the archipelago is designated a national park with strict protection. Commercial fishing in the coastal zone is completely prohibited, as is the issuance of permits for capital construction.

The result is pristine reef systems at depths ranging from 5 to 30 meters, home to hundreds of species of tropical fish and benthic invertebrates. The water is clear: there are no inflowing rivers, no turbid sediment, and underwater visibility reaches 20–25 meters. Green sea turtles regularly lay their eggs on the archipelago’s long beaches — the entire process is monitored by national park biologists. Tourists can obtain a one-time permit and watch the hatchlings under the supervision of security guards.

The island’s hotel inventory is artificially limited. The available accommodations are low-rise villas made of teak and natural stone, located at the edge of the forest and the shore. The rooms are cooled by the evening ocean breeze, not air conditioning. This isn’t a marketing ploy — it’s simply an architectural solution that works in this climate.

Basalt cliffs of Phu Yen Province

Phu Yen is a central eastern coastline that’s virtually absent from English-language guidebooks. Foreign tourists rarely make it here: there are no direct international flights, and the region itself doesn’t engage in aggressive tourism marketing. Domestic tourism here is developing naturally, without targeting foreign markets — and this is evident in prices, the atmosphere, and how locals react to visitors.

The main attraction of the coastline is the Gan Da Dia cliffs, formed by the rapid cooling of lava flows by seawater. The molten rock has cracked into perfect hexagonal black columns that descend vertically in wide steps. Waves constantly crash against them with a distinctive roar. Professional photographers come here at dawn — in the early hours, the shore is almost deserted, and the light is just right.

The province’s fishermen still set out to sea in round wicker boats coated with tree resin for waterproofing. The morning catch goes directly to family-run cafes, without middlemen or tourist markups.

The province’s coastline stretches for almost 200 kilometers — most of this distance is taken up by empty beaches without a single building on the horizon. Prices for fresh fish and seafood here are significantly lower than in Nha Trang or Da Nang, precisely because the tourist infrastructure doesn’t put pressure on the local economy.

How to plan an unconventional route

The logistics of traveling to remote locations require advance planning — this is the main difference from a standard package tour. Domestic flights connect Hanoi and Ho Chi Minh City with provincial airports, while small 70-seat turboprops fly to remote islands. Weather plays a role — during stormy season, the schedule changes regularly.

Land travel is best done in a rented car with a driver. Public transportation simply doesn’t reach the isolated eco-lodges in the mountains, and the quality of mountain roads after monsoon rains is unpredictable. The best month to travel depends strictly on the region: the mountainous north is comfortable from September to November, when the rice is ripening, temperatures drop, and there is little rain. The southern islands are best visited from February to May, when the seawater is calm and clear.

High-quality, remote eco-lodges typically offer several dozen rooms. Individual villas and boat cabins are booked five to six months in advance — spontaneous trips to such places rarely succeed for the simple reason that they’re full.
