Where We Dive - The Jewels Of The North Pacific
Diving in Guanacaste, Costa Rica
We operate in the North Pacific of Costa Rica, an area known for volcanic formations, strong currents, and large marine life. Our main dive areas include:
-
Catalina Islands – seasonal manta rays, eagle rays, turtles, white tip reef sharks, large schools of fish and many more.
-
Murcielago "Bat" Islands (seasonal) – advanced dives with pelagic encounters, well known for diving with bull sharks, manta ray encounters and large schools of fish
Conditions vary throughout the year, which allows us to match dive sites to diver experience and comfort level, making private guiding especially valuable in this region.
Diving Style - How Our Private Diving Works
Personalized Diving, Not Mass Tourism
Every dive with Uncharted Diving Expeditions is planned individually. We take into account:
-
Certification level and experience
-
Recent diving history
-
Comfort in currents and depth
-
Personal interests (marine life, photography, relaxed dives)
This approach allows us to slow things down for newer divers or step things up for more experienced ones, always prioritizing safety and enjoyment.
Who We Dive With - An Experience For All Levels
From first-time divers to experienced explorers
This is a great fit if you are:
-
A certified diver looking for personal attention
-
A couple, family, or small group traveling together
-
A newer diver who prefers a calm, unrushed experience
-
An experienced diver who values flexibility and site selection
This may not be the right fit if you are:
-
Looking for large group diving
-
Focused only on the lowest price
-
Expecting a resort-style, high-volume operation
Our focus is quality, safety, and personalized service, not volume.
