The Canary Islands are situated in the middle of the Atlantic Ocean, where the waves are strong and relentless. Many beaches are located along coasts that are dangerous for swimming, so seeking natural pools is a way to stay safe and enjoy the salt water. You’ll find over a dozen of these pools in Gran Canaria in all corners of the island. One of the loveliest is Las Salinas which was once used for salt production in the harbor town of Agaete, where the ferry runs to Tenerife Island. 
To get to the pools you can drive down the rural dirt road to find the parking lot, or take a short walk from the port town. There are three pools here with different sizes and depths, connected by submarine volcanic lava tubes.
As the tide changes the water is renewed keeping it perpetually clean, and also traps sea life for a time, making the pools a favorite spot for snorkelers. Be aware that during low tide the water is protected for swimming, and in high tide the turbulence can create a hazardous situation even in this sheltered area.
