Castlehill to Murkle is a unique surf spot that often flies under the radar. It's a rarely surfed stretch of heavy reefs that caters mainly to experienced surfers looking for a challenge. The waves here have a reputation for being grunty and shallow, so if you decide to check it out, make sure you're up for it. Originally known as Nothing Left, the spot has a local history tied to Andrew Manson, a long-time surfer in the area.
The surf here works best with north-west swell, but you can score decent waves with west and north swells too. It can handle swell sizes of around 3ft (approximately 1 meter). The waves usually break over rock ledges, offering left-hand reef waves that can provide some good rides for those who have the skills. Mid to high tides are preferable for the best conditions, especially with south winds, making those sessions more enjoyable. Just remember, this spot is definitely for experts—so be prepared and respect the ocean.
If you're planning to visit, you can park at Castlehill and take a walk west to explore the area. While you're at it, check out other nearby spots like Silos and The Pole, which also serve up some thick, ledgey lefts. Overall, it's a good idea to scope the place out and see what suits your surfing style best.
