For a safe family beach in Penzance, then Long Rock is worth a visit as it is the most accessible sandy beach in the town, handy for a soothing walk, then perhaps a pasty.
Popular with locals, windsurfers, kayakers and paddleboarders, it is also a safe swimming beach as it is gently shelving with small wave, so it takes a while to get out of your depth.
Some say it does not feel like a Cornish beach for that reason, but it is flat, about a mile long for easy walking with beautiful views of St Michael’s Mount, rather than a sunbathing beach, though children will love the shallow water and building sandcastles.
You can easily walk along the coastal path to Marazion or central Penzance from here, and it is a wonderful spot to get away from the crowds. Sea defences were improved here in 2019 to safeguard the area from winter storm waves.
With sand and pebbles (shingle when the tide is in) it is also dog-friendly, so if you want to avoid dogs, try the Marazion end.
The car park is a little hidden but well worth finding as it charges only £1 for 24 hours, a price almost unheard of in Cornwall. The Great Western Railway passes by, for train enthusiasts.
