Eastern Arch trip report describing wildlife and exposed surface conditions.
Eastern Arch
Arco de inmersión en mar abierto en el extremo oriental de Poor Knights.
Acerca de Eastern Arch
Eastern Arch es una inmersión avanzada en pared y arco en Poor Knights, donde una entrada occidental enmarcada por kelp conduce a paredes escarpadas cubiertas de esponjas y a una salida más expuesta hacia aguas azules en el lado exterior de las islas. El sitio se valora por su estructura dramática más que por su resguardo. Por lo general, los buceadores siguen la línea que el capitán elige para el día, observando nudibranquios, morenas, bancos de peces y rayas que pasan mientras el arco se abre hacia el océano abierto.

Local Intel For Eastern Arch
Community notes to help plan your visit.
Scuba
A wall-and-arch dive starting around 18 m and progressing to a vertical drop into 40 m+ with an open-ocean outlook.
Freedive
Not a typical freedive site. The exposed outer-island setting, boat logistics, and advanced underwater terrain make it better suited to scuba-led runs.
Snorkel
Generally unsuitable for casual snorkeling because the site is boat-only, exposed, and planned around advanced diving conditions rather than easy surface shelter.
