Freedive Northern Ireland, Johannes Windisch

Located in Portrush, Freedive NI operates along the dramatic Causeway Coast, a stretch of Northern Ireland known for its volcanic rock formations and deep kelp forests. The centre provides a gateway to some of the most striking coastal scenery in Ireland, from the chalk cliffs of Whiterocks to the sheltered bays of Portballintrae.

Since its establishment in 2019, the centre has focused on connecting people with the coastline through specialised disciplines. Rather than standard recreational diving, the emphasis here is on freediving, snorkelling, and paddleboarding, allowing for a closer, more intimate connection with the underwater environment.

The centre is run by Johannes Windisch, also known as Hanno Windisch, who provides expert guidance for all levels of experience. The team focuses on small group sessions to ensure personalised attention and a high standard of safety in the open water.

The instruction covers a range of skills, from introductory courses for beginners to advanced training for those seeking more technical challenges. Their approach is built on local knowledge, specifically regarding how the coastal conditions of the Causeway Coast behave.

The training programme is centred on freediving, offering everything from a Freediving Intro Course to more advanced sessions. For those looking to build a foundation in water confidence, the centre also provides training in Breathwork, Water Safety, and Surf Survival.

Beyond formal freediving certifications, the centre offers specialised vouchers for diverse activities. These include Cave Snorkel sessions, Cave SUP and Snorkel tours, and dedicated Seal Snorkel boat tours, allowing divers to apply their skills in varied coastal settings.

The marine life around the Causeway Coast is diverse, particularly within the kelp forests of the Skerries Islands. You will frequently encounter various fish species and crabs navigating the underwater terrain.

In the more open or sheltered coastal areas, it is common to see seals, which are a highlight for many snorkelers and freedivers. The rocky habitats also support sea anemones and starfish.

Macro life and smaller inhabitants are present throughout the region, including various crabs and other crustaceans that inhabit the crevices of the volcanic rocks and kelp canopy.

The coastal environment is highly dynamic, with tides playing a significant role in access and depth. Some entry points are easily managed at high water but can become difficult or expose slippery rock shelves during low tide.

Swell is a major factor for all activities. Even on clear days, a lingering swell can drive waves into coves, create surge inside sea caves, and stir up sand, which can impact visibility and movement.
