Located about 340 miles off the Pacific coast, Cocos Island is a UNESCO World Heritage Site that’s often referred to as the “Mecca of Scuba Diving”.

This cluster of rocky islets is one of the best places to spot giant manta rays. Located just off the Flamingo and Tamarindo beaches on the Pacific coast, the Catalina Islands offer excellent conditions for experienced divers. Visibility here is superb year-round, making it a sought-after spot for underwater photography.

Tips for First-Time Divers and Snorkelers

If you’re new to snorkeling or scuba diving, don’t worry—Costa Rica has something to offer for every experience level. Here are a few tips to help you make the most of your underwater venture:

  • Get the Right Gear: Invest in a high-quality snorkel and mask to avoid leaks. For first-time divers, reliable operators typically provide all necessary equipment, including wetsuits and oxygen tanks.
  • Take a Lesson: Many of Costa Rica’s top spots offer beginner-friendly tours. If you’re new to scuba, consider a Discover Scuba Diving course, which lets you practice essential skills in shallow water.
  • Choose a Reputable Tour Operator: Seek operators that are certified by organizations like PADI or SSI. Not only are they safer, but they also follow eco-friendly practices.
  • Stay Relaxed: It’s natural to feel a little nervous at first, but try to stay calm and enjoy the moment—it’s worth every second.

The Best Time to Scuba Dive and Snorkel in Costa Rica

Timing matters when planning your underwater adventures, as Costa Rica’s seasons can impact marine visibility and wildlife sightings.

  • Best Time for the Pacific Coast: December to April offers calmer seas and perfect visibility, whereas May to November attracts larger marine species due to the nutrient-rich water.
  • Best Time for Cocos Island: The dry season (December-May) is ideal for spotting schools of hammerhead sharks and other large pelagic species.
  • Best Time for the Caribbean Coast: September and October are known for warm, clear waters, perfect for snorkeling.

Whenever you choose to visit, Costa Rica’s marine life will never disappoint.

Sustainable Practices and Conservation Efforts

Costa Rica is a global leader in eco-friendly tourism, and you can support this effort while exploring its underwater world.

  • Practice “Leave No Trace” Diving: Don’t touch marine animals or coral as they are delicate ecosystems.
  • Use Reef-Safe Sunscreen: Regular sunscreens can harm coral reefs, so be sure to use eco-friendly products.
  • Choose Responsible Tour Operators: Many tour companies support conservation initiatives, like beach clean-ups and marine protection programs.
