Car parking is available at 68 Portmuck Road. From here, it is a short walk to the harbour wall, from where you can entre the water directly from the harbour wall (watching out for boat traffic) or climb over the rocks behind the harbour to dive in the small enclosed cove on the north east side.
Portmuck Harbour provides a slipway and public toilets. The pier is 25 metres long, 6.5 metres wide and in good condition.
- Strong northerly tidal currents
- Discarded fishing tackle (this is a popular site for anglers)
- Recreational boat traffic.
- It is worth speaking to the harbour master prior to your dive.
This site can be dived either side of the harbour wall. Bedrock extends out from the harbour wall and follows the coastline to the north east, forming a steep vertical wall, beneath which the seabed is comprised of fine sand. The area inside the harbour wall is a sheltered sandy bay, with a steep bedrock wall on the seaward side. This wall is covered in dense and diverse seaweeds and is a suitable site for training dives.
A diverse community of crustaceans, sea squirts and soft corals are found amongst a variety of alga species, including kelp, attached to the bedrock wall (at both sites either side of the harbour wall).
