Costa Rica Scuba Diving: Open Water, Discovery Dives, Best Time, Best Spots and More

As someone who spent much of her childhood in and around water and studied to be a marine biologist, I had always wanted to get my scuba diving certification. Although my dream of being a marine biologist didn’t quite pan out, I ended up living very close to the beach in Costa Rica.

I feel so grateful to be so close to the ocean and have the opportunity to enjoy the many water sports like surfing and snorkeling. And now, I’m able to add one more to my list – scuba diving!

I recently completed my PADI open water certification and if you are thinking about scuba diving in Costa Rica or getting your certification, here’s my experience and Costa Rica scuba diving review.

Snuba

My first experience with scuba diving in Costa Rica was actually a snuba tour.

Snuba is a combination of snorkeling and scuba diving. You have fins, mask and weights but instead of carrying a cylinder for air, the air comes from cylinders in a surface floating device connected by long hoses. You’re able to stay under the surface up to 6 meters/20 feet.

I absolutely loved snuba. It was my first time actually staying down in the water, I’ve only ever snorkeled before. I loved the feeling of being underwater and seeing all the marine life up close. From that moment on, I knew scuba diving was something I had to accomplish in my life.

I highly recommend snuba for anyone who wants to go beyond snorkeling. It’s a completely different experience being under the water than floating on the top. And maybe it will also inspire you to get your scuba diving certification too! It’s an excellent adventure and one of the best things to do in Costa Rica.

Scuba Diving, Costa Rica

If you ever wondered if you need to be certified to go scuba diving in Costa Rica, you do not. Many scuba diving companies in Costa Rica offer what they call a “discovery dive” which is specifically for people who don’t have their certification. Before getting my certification, I did a discovery dive to get a feel for scuba diving.

The two tank discovery dive from Flamingo was incredible. We did a one hour instruction in the pool before the two tank dive at Las Catalinas Islands. While diving, the team took great care of us, checking all our equipment and making sure we were OK. We just focused on swimming and enjoying the underwater world.

Although it was windy, the water clarity was great. We saw manta rays, sea stars, eels, octupuses, whitetip reef sharks, nudibranchs and big schools of fish. On the boat ride, we saw dolphins and humpback whales breaching!

That discovery dive lit a fire in me. Scuba diving was like entering a completely different world and I was just a quiet observer and humble guest in this foreign kingdom. I signed up for my PADI open water almost immediately afterwards!

Scuba Diving in Guanacaste, Costa Rica (My PADI Open Water Course)

I signed up to do the course with a friend and this was our itinerary. The PADI open water course consisted of 3 in person days and 1 day of theory. I completed the theory the day before the pool instruction.

• Day 1: Pool Instruction
  • This took about 3 hours. Since it was just the two of us, we had one instructor. The pool day was to get used to the equipment, learn how to put the BCDs together, how to achieve neutral buoyancy, safety stops, hand signs and more.
• Day 2: First day two tank dives at Las Catalinas Islands
  • We departed from Flamingo for the Catalinas Islands, about a 30 minute boat ride. On the boat ride there, our instructor went over what we would practice during the dives so we knew what to expect.
• Day 3: Second day of two tank dives at Las Catalinas Islands
  • The last day we did safety stops, compass and practiced a few more exercises. The very last dive was more of a fun dive and reinforced more exercises we practiced.
  • After we completed the last dive, that was it! Our instructor signed us off and we were officially PADI open water certified!
  • We went back to the office to take our picture for our certification card and I picked up my card and dive book a couple weeks later.
• Price of PADI open water certification in Costa Rica is between $400-550 USD.

Photos

Here are some photos from my dives. I didn’t take any during the course but I got a lot of photos on my discovery dive. Below you can see some of the beautiful marine life at Las Catalinas Islands.

I’m excited to scuba dive more and hopefully start working towards getting my advanced!

Best Time to Scuba Dive in Costa Rica

July and August are some of the best times to scuba dive in Costa Rica because it is the humpback whale and turtle season. I did my discovery dive in August and my course in September and we heard humpback whales singing! They were so loud, I thought they were swimming over my head! Water clarity during rainy season is also great for scuba diving.

Likewise, February is a great month to scuba dive in Costa Rica to see the giant oceanic manta rays but the water temperature is colder. Humpback whales also pass through Costa Rica in January and February so you may see or hear them, especially if you scuba dive at Caño Island down in the South Pacific.

May – November is rainy season in Costa Rica s the waves were rocky when I went in August as a tropical wave was passing through the country. Many people on the boat got seasick. Thankfully, I took anti-nausea medicine so I was fine (thank goodness). For our course in September, we didn’t have any wind for both days. It was sunny and very pleasant.

Scuba Diving, Playa Flamingo, Costa Rica

Although I actually live in Tamarindo, I did my dives out of Flamingo instead. This was because of a friend who works closely with the dive shop. When she heard that I was interested in scuba diving, she helped us with the discovery dive and schedule our course. Flamingo from Tamarindo is about a 30 minute drive one way.
