Alicante's beaches are safe for swimming. They have lifeguards in season and good water quality. The most real risk is theft of belongings while you swim: don't leave anything valuable alone on the sand.

Postiguet Beach

Alicante's most central beach, right below the Castle. Fine sand, calm waters, promenade with beach bars. Very popular with tourists and locals, especially in summer.

  • Advantages: easy access from downtown, elevator to Castle, facilities (showers, toilets, rentals)
  • Disadvantages: gets very crowded in July-August, less space than San Juan
  • Watch out: more pickpocketing than San Juan due to tourist traffic

San Juan Beach

7 kilometers of golden sand, wide promenade, family atmosphere. It's the preferred beach for residents and families. More space, less stress, better for spending the whole day.

Protecting your belongings

Golden rule

  • NEVER leave valuables alone on the sand while swimming
  • Use a waterproof pouch to take phone/wallet into the water
  • Take turns watching with your group: someone always stays with the stuff
  • If alone, bring only essentials (ID copy, little cash)
  • Avoid expensive backpacks or flashy bags: simple cloth bags go unnoticed
  • Towel over the backpack doesn't fool anyone: it's the most known technique
  • Some beach bars offer storage service (ask)

Water safety

  • Respect the flags: green (OK), yellow (caution), red (swimming prohibited)
  • On yellow flag days there are currents: don't go far from shore
  • Lifeguards are on duty 10:30-19:30 in high season
  • With small children, keep visual contact: water is calm but they can get scared

The promenade: day and night

Both Postiguet and San Juan have wide, safe promenades. During the day it's full of walkers, runners and cyclists; at night the lighting is good and terraces stay open late.

  • At night the promenade is safe, but avoid unlit remote areas
  • Don't leave bags on chair backs at terraces (pickpocketing)
  • Skaters and bikes have their own lane: watch when crossing

Conclusion

Alicante's beaches are safe and well-equipped. The biggest risk is theft of belongings: never leave them alone. Postiguet is more central but crowded; San Juan has more space and is ideal for families. Enjoy the sun, but use your head.
