Long Beach (Oneroa Bay) is one of Russell's safest swimming beaches, offering sheltered, calm waters ideal for families with children. The beach is protected from prevailing winds and large swells, creating gentle conditions most of the time. There are no lifeguard patrols, so parents should supervise children closely. The sandy bottom slopes gradually, making it comfortable for paddling and swimming. Water quality is generally very good. The beach's proximity to town means help is nearby if needed, adding to its family-friendly appeal.

The best time to visit Long Beach is during New Zealand's summer months from December through March, when weather is warmest and water temperatures are most comfortable for swimming. The beach is pleasant year-round due to its sheltered position, though winter can be cooler. For fewer crowds while maintaining good weather, visit during November or April. The beach is accessible anytime and offers beautiful sunrises. Consider visiting during weekdays in peak season to avoid the busiest periods when cruise ships visit Russell.

Long Beach is easily accessible from Russell's town center via a pleasant 10-15 minute walk along the waterfront. Head north from the main wharf area along The Strand, which becomes Oneroa Road, leading directly to the beach. The walk is flat and scenic, suitable for all fitness levels. Limited parking is available near the beach for those driving. Russell itself is reached by passenger ferry from Paihia (12 minutes) or vehicle ferry from Opua, or by road via Whakapara. The beach's proximity to town makes it very convenient for visitors.

Long Beach is within easy walking distance of Russell's town center, which offers a range of accommodation from luxury lodges and boutique hotels to holiday homes and backpackers. Several properties provide beachfront or near-beach locations. Russell township features numerous cafes, restaurants, and a general store for supplies, all within 10-15 minutes' walk. Options range from casual fish and chips to fine dining featuring local seafood. The Duke of Marlborough Hotel is New Zealand's oldest licensed hotel and offers both accommodation and dining near the waterfront.

Long Beach stands out as Russell's main swimming beach, combining sheltered swimming conditions with immediate proximity to a historic town rich in New Zealand's colonial heritage. Unlike many Bay of Islands beaches requiring boat access, Long Beach offers easy walking access from cafes, shops, and accommodations. The beach provides a more relaxed, local atmosphere compared to busier Paihia Beach across the bay. Its position makes it ideal for visitors who want beach time combined with exploring Russell's museums, historic buildings, and waterfront restaurants without needing to drive.
