Castlepoint Beach is a long, sandy bay on the Wairarapa coast, approximately an hour's drive from Masterton. The primary access for paddlers is from the beach itself, with a large carpark located at the road end. The carry distance from the carpark to the water's edge is short. This is a shared-use area where vehicles, including those towing boats, are permitted on the beach, so paddlers must remain alert for other users when launching or landing. The beach faces the open ocean and receives solid swell, making it exposed to wind and waves. Conditions can change rapidly, with large, dangerous swells occurring. There is no lifeguard service on the main beach. A significant geographical feature is the long sandspit, which creates a sheltered lagoon with calmer water suitable for swimming, paddleboarding, and kayaking. This lagoon offers a protected alternative to the open surf. The reef and sea conditions around the point are extremely dangerous and unpredictable, with risks from tidal and rogue waves; paddlers should avoid this hazardous area. Notable sights from the water include the historic Castlepoint Lighthouse perched on a rocky headland and the distinctive 162-meter-high Castle Rock sea stack. The area is part of the Castlepoint Scenic Reserve, frequented by several species of dolphin, New Zealand fur seals, and occasionally small whales. Seabirds are abundant. Facilities at the beachfront include a store, tearooms, public toilets, and a shower. The Castlepoint Holiday Park at the northern end of the beach offers accommodation and campsites with direct beach access. The overall character is that of a raw, scenic coastline with a mix of exposed surf beach and sheltered lagoon pockets, popular for a variety of watersports but requiring caution due to its exposed nature and shared use with vehicles.
