  • How do I make a reservation?

  • What are the seasons like in Costa Rica?  There are two seasons that affect us in Guanacaste, The DRY season (summer) and the RAINY season (winter).  Both are great times to visit.  In the dry season many of the trees exchange their leaves for colourful flowers. During the rainy season, Guanacaste becomes a lush tropical garden. 
  • When is the best time of year to come to Costa Rica? 

    We always say, “Any time you can get here”. 

  • When is dry season and when is rainy season? 

    Dry season is November through April. The Papagayo winds blow this time of year, however mornings are usually calm.  Visibility averages from 15-40ft / 3-12m with water temperature averaging from 70-75F /21-24C with thermoclines. A 5/3mm wetsuit is recommended. Rainy season is May through October with September and October being the wettest months.  Mornings are usually sunny with afternoon rain showers, clearing in the evening for fantastic sunsets.  Visibility averages 20-60ft / 7-20m with water temperature averaging 75-85F / 24c-30C with cooler thermoclines.

  • Do you need to be certified to dive?
