The coastline around Altea is one of the most breathtaking stretches of the Costa Blanca, dramatic cliffs, turquoise water, marine reserves, and secret bays that you can only reach by boat. At Enjoy Boats we know you’re looking for a truly unforgettable adventure and these seven hidden coves are the crown jewels of the area.
Each one offers something unique: crystal-clear water for snorkeling, peaceful corners for sunbathing, dramatic rock formations, or untouched nature that feels worlds away from the Costa Blanca’s busier beaches.
1. Cala del Soio (Mascarat)
A peaceful, narrow cove tucked beneath towering cliffs. The water here is startlingly clear, perfect for swimming and snorkeling.
Expect tranquility, deep blue water, and the feeling that you’ve discovered your own private corner of paradise.
Best for: snorkeling, couples, quiet mornings
Why go by boat: far fewer people, and the views of the cliffs from the water are breathtaking.
2. Racó del Corb (the “Forbidden Cove”)
