Grassy Head Beach is generally suitable for swimming, though conditions vary with weather and swell. The beach is unpatrolled, so swimmers should exercise caution and stay within their abilities. The southern end near the headland typically offers calmer conditions, while the northern stretch can experience stronger currents and surf. Always check local conditions before entering the water, avoid swimming alone, and be particularly careful during high tide or after storms. The beach is popular with surfers, so be aware of board riders in the water.

Grassy Head Beach is enjoyable year-round, with each season offering different appeals. Summer (December-February) brings warm weather ideal for swimming and water activities, though it's busier. Autumn and spring offer mild temperatures, fewer crowds, and excellent conditions for walking and surfing. Winter (June-August) sees cooler weather but can provide spectacular whale-watching opportunities and dramatic coastal scenery. The beach faces east, making it perfect for sunrise viewing any time of year. Generally, weekdays are quieter than weekends regardless of season.

Grassy Head Beach is located approximately 8 kilometres north of Stuarts Point. From the Pacific Highway, take the Stuarts Point exit and follow signposted roads through Grassy Head village. The main access is via Grassy Head Road, which leads to a parking area near the beach. Parking is free and generally adequate, though spaces can fill during peak holiday periods and summer weekends. The beach access involves a short walk from the car park. The roads are sealed and suitable for conventional vehicles.

Grassy Head village is small and has limited facilities. Basic supplies and takeaway food can be found at the general store, but for broader shopping and dining options, nearby Stuarts Point (8km south) or Macksville (20km) offer more choices. Accommodation options include holiday houses, camping at local caravan parks, and rental properties, though booking ahead is essential during school holidays. The beach itself has no kiosks or facilities, so bring your own food, water, and supplies for the day.

The Grassy Head headland walk offers spectacular elevated coastal views and is one of the area's highlights. The walking track leads to the rocky headland providing panoramic ocean vistas, opportunities to spot dolphins and migrating whales (June-November), and dramatic scenery of the coastline. The walk is relatively easy and suitable for most fitness levels. The headland's unique vantage point makes it popular for photography, particularly at sunrise and sunset. The combination of beach access and headland walking in one location makes Grassy Head particularly appealing to visitors.
