The kids will sleep soundly after having fun in the sun at Playa de Faneroque. Look for crabs and other little critters, stick a toe in the water or toss a Frisbee around!
You're spoiled for sightseeing choice in Agaete. Playa de Faneroque is an ideal place to kick off here, but there are loads of other worthwhile sights to discover. Agaete Natural Pools, Agaete Botanical Gardens, and Playa La Caleta are close to the stretch of coastline and will round out your day nicely.
