About Craiglockhart

Craiglockhart sits in the working farmland of the Waihopai Valley. The swim site features a wide, deep pool that remains cold even in summer, fed by the mountain catchment of the Waihopai River. A vehicle track branches off the road just past the No. 2 Bridge and descends to the gravel bar, providing easy access to both deeper water and shallower margins upstream.

The pool is a long-standing local favourite, known for its clear water and the distinctive rock formation on one bank. Steep, bush-covered hills surround the area, creating a sense of isolation. The river flows swiftly through the gorge above the site, so currents can be felt even in calmer-looking sections.

Marlborough District Council and LAWA monitor the site for recreational water quality. Visitors should always check the latest readings, particularly after rain when bacterial levels can rise due to runoff from surrounding farmland. No mobile coverage exists in parts of the valley, adding to the remote character of the spot.

Safety and Conditions

Swimmers must be confident in cold water and able to handle currents. LAWA guidance emphasises that users should be comfortable swimming at least 100 metres before entering deeper sections. There are no lifeguards or rescue equipment at this rural location.

Water quality is tested regularly for E. coli and toxic algae. Conditions can change quickly after heavy rain or during low-flow summer periods when algal mats may appear. Always consult the current LAWA status before travelling.

The site has no facilities. Visitors should bring drinking water, sun protection, and take all rubbish away. Fires are permitted only with the appropriate permit in some cases.

What Visitors Often Say

Locals describe it as a peaceful, scenic spot ideal for a quiet swim or picnic on hot days, with the deep pool as the main attraction and shallower areas suitable for paddling.

Visitors note the cold water and strong currents require caution, appreciate the lack of crowds, and stress the importance of checking water quality and leaving no trace.
