About Bat Cave
Bat Cave es un divertido reef break escondido en el archipiélago de las Mentawai, con olas potentes y huecas que premian a los surfistas capaces de leer los fondos de arrecife. Funciona mejor con un swell sólido, generando secciones cortas y poderosas ideales para practicar el barrel riding y los giros rápidos. Los surfistas de nivel intermedio encontrarán en él un salto satisfactorio respecto a los beach breaks suaves, aunque el arrecife exige respeto y calzado adecuado fuera del agua. El pico suele estar menos concurrido que los spots más famosos de las Mentawai.
Local knowledge
El arrecife es poco profundo, afilado y está cubierto de coral vivo — una caída en una ola de serie puede provocar cortes serios o algo peor, por lo que se recomienda encarecidamente casco y reef booties. Vigila los erizos de mar en las zonas más someras cerca del canal de entrada, y ten cuidado con las corrientes que pueden arrastrarte a lo largo del borde del arrecife cuando el swell está activo. El tráfico de embarcaciones —barcos charter y taxis acuáticos— puede sorprenderte en el canal, así que mantente alerta.
Bat Cave es un spot al que solo se puede acceder en barco dentro de las Mentawai — llegarás en un barco charter o en una lancha rápida de excursión de día desde Padang o desde alguna de las bases insulares cercanas (zona de Macaronis Resort). Fondea en el canal, evalúa el arrecife desde la embarcación antes de remar hacia fuera, y utiliza el canal de aguas más profundas para entrar y salir con seguridad en lugar de intentar cruzar el arrecife seco.
Una shortboard versátil de entre 6'0" y 6'4" con algo de volumen extra maneja bien las secciones potentes y huecas la mayoría de los días; trae una step-up (6'4"–6'8") si hay un swell sólido de 4–6 pies para mantener el control en las paredes más pesadas y rápidas. Olvídate de la fish o el longboard — el carácter rápido y ledging del arrecife premia las tablas con rocker y agarre.
mellow — relaxed vibe.

Surfing in Mentawai
Full Mentawai surf guide →If there's one name that makes surfers go quiet and start saving, it's the Mentawai. This remote archipelago of more than 70 islands sits off the west coast of Sumatra, fully exposed to raw Indian Ocean swell, and it has earned its reputation as one of the most concentrated, high-quality wave zones on Earth.
✈️Getting there
All routes run through Padang, the port city in West Sumatra. Fly into Padang's Minangkabau International Airport (PDG), usually via Jakarta, or via Kuala Lumpur or Singapore on regional carriers.
🛵Getting around
The Mentawai are about boats, not roads. Once you arrive, your daily transport to the waves is by boat — either the liveaboard itself or the resort's tenders and speedboats running surfers out to the breaks.
🌤️Climate & season
The Mentawai are equatorial, hot and humid year-round, with water warm enough for boardshorts or a thin top (roughly 27–29°C). There's no real winter — just wetter and drier patterns.
