Co Thach Beach in Lien Huong, Vietnam

Co Thach Beach is the coastal attraction around the former Binh Thanh area of Tuy Phong, now within Lien Huong commune, Lam Dong Province after Vietnam’s recent administrative reorganization. The old Travel S Helper record routed it through Phan Thiet, but current provincial planning and 2026 tourism reporting place the Co Thach–Binh Thanh tourism area in Lien Huong. The beach is best known not for a broad resort-style swimming strip but for its multicolored pebble shore, nearby Co Thach Pagoda and a rugged coastal landscape that rewards walking and photography. Travelers expecting soft sand everywhere should adjust those expectations before arriving.

The most distinctive feature is Bai Da Ca Duoc, commonly called the Seven-Color Rock Beach. Recent Lam Dong reporting places it directly within the Co Thach coast at Lien Huong and describes more than a kilometer of small rounded pebbles in varied colors. Older geological reporting from the same provincial press gives a longer documented history of the deposit and explains that waves and currents have continually shaped and moved the stones. The result is a shore that changes visually with water, light and tide rather than presenting one fixed arrangement.

This geological character means the beach is better for observation, coastal walking and photography than for treating every section as a conventional bathing zone. Smooth pebbles can be unstable underfoot, wet stones can be slippery, and waves can wash farther up the shore than expected. Swimming may be possible at suitable sandy or calmer sections, but the strongest sources do not publish a current, universal supervised-swimming map. Visitors should choose clearly used bathing areas and follow local instructions rather than entering the sea directly from the most rocky sections.

Co Thach is also tied closely to cultural and religious tourism. The surrounding destination includes Co Thach Pagoda, an old temple complex associated with the coastal hills and caves, and the local tourism authority is actively promoting routes that combine the pagoda, the seven-color rock beach, fishing-community scenery and other Lien Huong attractions. This mix makes the area suitable for a half-day or full-day visit even when rough sea conditions reduce swimming options.

Current 2026 provincial reporting confirms that authorities are actively developing tour connections in Lien Huong and recognize Co Thach, the seven-color rock beach and related heritage sites as important tourism assets. Provincial planning documents for 2026–2030 likewise list the Co Thach–Binh Thanh tourism area under Lien Huong. These sources are useful because they remove the ambiguity created by older maps that still show Binh Thuan Province, Tuy Phong District or Phan Thiet as the primary locality.

No dependable current seven-day public opening schedule or general beach admission fee was found for the natural shore itself. Individual attractions, parking areas, religious sites or commercial services may operate on their own schedules and may charge separately. Travelers should therefore avoid assuming that a parking fee or local service charge is an entrance ticket to the entire coast. Arriving in daylight is the safest and most practical choice for walking the pebble sections.

Road access is straightforward for independent travelers. The destination is reached by the coastal and national-road network serving Lien Huong, and recent provincial reporting notes that improved regional road connections are helping tourism growth. Private car, taxi or scooter are the clearest options. Because administrative names changed after the 2025 reorganization, navigation works best with “Co Thach Beach, Lien Huong, Lam Dong” or “Bai da 7 mau Co Thach” rather than an old Phan Thiet route.

The beach’s visual condition can vary by season. Algae or moss can appear on some rocks at certain times, while wave action can cover or expose different stretches of pebble. That variability is part of the coast’s natural character but also means social-media images should not be treated as a promise of identical conditions. Strong wind or rough surf can make the rocky shoreline uncomfortable, and visitors should be willing to shift the emphasis from swimming to walking, photography or the pagoda.

Accessibility is limited by the beach surface. Pebbles, rocks, steps and irregular coastal paths are significant barriers, and no current source confirmed beach wheelchairs or a continuous step-free route along the shore. Visitors with reduced mobility may still be able to enjoy viewpoints or nearby paved areas, but should confirm the easiest access point locally before traveling.

A good visit allows three to five hours. That gives enough time for the pebble beach, the pagoda area, a meal and unhurried coastal views. Travelers should wear shoes or secure sandals with grip rather than thin flip-flops if they plan to walk on wet stones. Sun protection and drinking water are also useful because shade can be limited along open stretches of coast.

Co Thach Beach is therefore most valuable as a combined landscape and cultural destination rather than as a simple “beach day” replacement for Mũi Né or Phan Thiết. The seven-color pebble shore is the defining reason to come, while Lien Huong’s religious and fishing-coast context gives the visit more depth. The essential planning correction is to route the destination to Lien Huong in Lam Dong and to approach the shoreline with footwear and expectations suited to rock and pebble terrain.
