Phong Nha is about to reach a new audience through Bollywood. With SILAA bringing Vietnam’s caves and landscapes to the big screen, moviegoers may soon find themselves wondering what these places are like beyond the frame. Here is where the film was shot, what makes the scenery distinctive, and how to plan a visit of your own.

A Bollywood Blockbuster, SILAA, Is Coming Soon

SILAA is an action-romance directed by Omung Kumar and starring Harshvardhan Rane, Sadia Khateeb, and Karanveer Mehra. According to a Times of India report published on October 25, 2026, the film is scheduled to arrive in cinemas on February 5, 2027. Its story of love and revenge unfolds across Kashmir and Vietnam, with scenes that take the cast and crew far from a conventional studio set.

Where Was SILAA Filmed in Vietnam?

The crew arrived in Quang Tri on July 30, 2025. The Quang Tri Department of Culture, Sports and Tourism lists Son Doong, Phong Nha Cave, Tan Hoa, Tu Lan, and Hang Tien among the province’s filming locations. The production also filmed in other parts of Vietnam.

Some of the behind-the-scenes images offer a glimpse of the work involved: cameras, lighting, and crew members moving through the rugged limestone landscape and into the cave environment.

Discover the Landscapes Behind SILAA

Phong Nha’s appeal lies in the contrast between its immense limestone mountains and the quiet movement of its rivers. Forest surrounds the cave entrances; underground water disappears into darkness, while the Son River winds through a landscape that feels both expansive and intimate. A film crew can use these shifts in scale and light to create a world that would be difficult to reproduce on a set.

Son Doong, where the crew reportedly spent four days filming, is an extraordinary expedition destination. The cave is not open for independent visits, and access is limited to authorized expeditions. Other locations around Phong Nha offer easier ways to appreciate the region’s caves, waterways, and forest scenery.

What Can You Experience in Phong Nha?

You do not need to join a multi-day expedition to enjoy Phong Nha. A boat ride along the Son River into Phong Nha Cave offers an easy introduction to the area’s underground waterways. Paradise Cave lets visitors walk along a constructed path beneath sweeping limestone formations, while the Chay River–Dark Cave area combines river scenery with outdoor activities. Each experience has different access conditions and activity levels, so you can choose a pace that suits your group.

If you are deciding between caves, transfers, and activities with limited time, a local itinerary can make the days easier to coordinate.

What Travelers Should Know Before Their Trip

Phong Nha is a rural destination, so plan how you will travel between Dong Hoi and the caves, and allow enough time for transfers. Check the weather and current operating conditions before setting out, especially for river-based activities.

Cave visits also vary in physical demand: popular sightseeing routes can be gentle, while expedition trips require advance planning, suitable fitness, and authorized access. If you have dietary preferences, let your accommodation or tour provider know ahead of time so they can advise what is available.
