Rainier III Nautical Stadium, Saltwater swimming stadium at Port Hercule, Monaco
The Rainier III Nautical Stadium sits within Port Hercule and contains seawater pools used for both competition and recreation. The facility houses multiple pools of different sizes, diving structures at varying heights, and transforms seasonally to serve different purposes.
The facility opened in 1986 on a harbor site that had served sporting purposes since 1949. This location became part of Monaco's broader development to establish water sports as a centerpiece of its coastal activity.
The facility holds an important place in Monaco's sports life, drawing competitive swimmers and divers from across the region. Local swimming clubs use the pools regularly, and the venue hosts events that bring the community together around water sports.
The facility opens from April through October with extended hours during summer months, so plan your visit around these seasons. In winter, part of the space converts to an ice rink, so check what's available when you visit.
The stadium includes diving platforms at multiple heights alongside a water slide for recreation. This combination makes it a place where serious training and family-friendly fun happen side by side.
