Tasman Arch

Tasman Arch is a natural coastal rock arch located in Tasman National Park near Eaglehawk Neck on the Tasman Peninsula, Tasmania. Formed by coastal erosion of Permian mudstone and sandstone, it spans a narrow isthmus with the sea visible through its opening. Notable for its dramatic cliff-top setting, accessible viewing platforms, and proximity to Devils Kitchen and the Blowhole, it is a key stop on the Tasman Peninsula scenic drive south of Hobart.

Visitors can expect a large natural rock arch spanning a coastal headland with the ocean visible beneath it, viewed from fenced cliff-top viewing platforms. The site is set within coastal heath and dramatic dolerite cliffs of Tasman National Park. A short paved walk from the car park leads to upper and lower lookouts over the arch and coastline. There are interpretive signs, no beach access, and views of the Tasman Sea and surrounding cliffs.

Tasman Arch is a geological feature formed by the erosion of Permian mudstone and sandstone and the collapse of a sea cave roof, creating a natural bridge. It illustrates coastal geomorphology of the Tasman Peninsula and has been a documented scenic landmark since the early 20th century within what is now Tasman National Park, established in 1999.

As part of Tasman National Park on the Tasman Peninsula, the arch is a significant natural landmark and scenic attraction that contributes to the region's nature-based tourism and appreciation of Tasmania's coastal landscape.
