Las Grutas and the San Antonio towns are reached primarily by road. Municipal tourism lists RN3 as the principal north/south approach, with RN251 and RP2 as other regional approaches. Viedma's Gobernador Edgardo Castello Airport (VDM) is the nearest documented scheduled-air entry point, with Argentine tourism describing an onward road connection of about 193 km to Las Grutas. In August 2026 Rio Negro confirmed Aerolineas Argentinas flights between Buenos Aires Aeroparque and Viedma six times weekly, but flight times and availability must be rechecked. Reserve a car, authorized transfer or verified bus connection before arrival; a flight is not a transfer to the dive dock.
Choose Las Grutas for an easy town and dive-provider base, San Antonio Oeste for town services and heritage, or San Antonio Este for port-side wildlife boats and beaches. Municipal tourism places them on the same regional road network, but boat boarding points are not interchangeable.
