From the city take the Nepean Highway (Route 3) south approx 40 km to Frankston. Continue a further 7 to 8 km then look for the sign to turn right to Sunnyside Beach. Turn right here and drive down this road for about 800 metres to the car park at the end. In summer you may have to park well short of the car park particularly on weekends. Do be careful of driveways and No Parking signs, as the area is regularly patrolled by parking inspectors. The best time to arrive is before 10am on a hot day, which will also give you a chance to pick your spot on the sand.
From the carpark or road, walk on to Sunnyside Beach then proceed north (to the right) around the rocky point to North Sunnyside. The walk is not that long, but it does go over a little bit of rock, a little dune, and mostly sand (depending on the tide). The beach itself is golden sand with some rock â€“ watch out for rocks in the water in some places, otherwise it is a sandy bottom with little seaweed. This is a bay beach so there is not much wave motion (if any!).
The beach itself is quite long, and is bordered by a private property where a fence has been installed. This actually helps the quality of the beach, as there is little cover for hiding undesireables in the dunes like other beaches. There is generally good shelter from the wind, but there is no shelter from the sun so make sure you bring along an umbrella (and some tie-downs if there is a chance of strong wind).
In the warmer months there is a great mix of singles, couples and families, particularly from midday through to sunset. It is a very friendly beach, and you can usually find people from the various forums and social clubs in attendance.
