Santa Teresa is primarily a surf town; formal scuba operations are limited locally and mostly concentrated in the adjacent Montezuma/Cabuya area of the same peninsula (within the broader Mal Pais–Santa Teresa–Montezuma corridor).

Good to know
Good to Know
- Diving here is boat-day-trip diving out of small, locally-run operators — there's no shore diving and no Santa Teresa-based liveaboard; don't confuse this with Costa Rica's famous liveaboard-only Cocos Island diving, which is a separate multi-day trip from a different part of the country entirely.
- Conditions can be genuinely unpredictable — expect operators to sometimes change sites or cancel/reschedule dives if visibility or current isn't safe, rather than push through poor conditions.
- If you want classic clear-water, coral-heavy diving, this isn't it — expect volcanic rock/pinnacle terrain with real shark, ray and pelagic encounters rather than a colorful coral reef.
- Dry season (roughly Dec–April/May) is the more reliable window for visibility; green season trades some visibility for richer marine life activity.
- If diving is a priority, treat Santa Teresa as a base for day trips rather than expecting a full-service dive center in town — confirm directly with any operator that they are currently running Open Water courses before planning around it.
- Visibility and conditions on this stretch of coast are generally more current- and swell-affected than Costa Rica's more sheltered dive destinations (like Golfo Dulce or Caño Island), so this area is not typically marketed as a premier dive destination.
Dive Sites And Conditions
- Access Type
- Boat-based day diving, NOT shore diving and NOT liveaboard-dependent. Local operators (based in Malpaís/Santa Teresa) run their own small boats out to nearby sites; there is no shore-entry diving here and no liveaboard operation based in Santa Teresa itself.
- Reef Vs Wreck Vs Wall
- This is a rock-reef/pinnacle diving destination on Costa Rica's Pacific coast — true coral reef coverage is limited (sources describe it as having 'only few reefs and corals present' compared to Caribbean diving), with volcanic rock formations doing most of the ecological heavy lifting. No named wreck dives were found for this immediate area.
- Visibility And Conditions
- Visibility is genuinely variable and conditions can be more challenging than tropical Caribbean diving: sources range from a low of roughly 2–7 meters (one Tortuga Island trip operator) up to 18–30 meters (60–100 feet) in dry season per another local source. Current can be strong enough that operators sometimes abort or relocate dives — a real customer review described a booked two-tank dive being called off entirely due to low visibility and strong current, with a refund offered rather than diving in unsafe conditions.
Named Sites
Isla Tortuga (Tortuga Island) Sites
- Type
- Rocky/volcanic reef over a mixed sandy-rock bottom, generally shallow and calm
- Best Season
- Dry season (mid-December to April) for best visibility
- Marine Life
- Large schools of yellowtail, spotted eagle rays, stingrays, angelfish, parrotfish, seahorses, octopus, needlefish, moray eels, white tip sharks, sea turtles, dolphins, and occasional whale sharks reported by guides.
- Notes
- Regarded as one of the calmer, more beginner-friendly sites in the region since current is minimal around the island; often combined with a snorkeling/beach day rather than run as a pure dive-only trip.
Cabo Blanco 'Spill-over' Sites (Malpaís/Cabuya Outer Waters)
- Type
- Rocky reef and pinnacle formations
- Best Season
- Dry season (December–May) for clearer water; green season for richer nutrient-driven marine activity
- Marine Life
- White tip reef sharks, blacktip reef sharks, nurse sharks, manta and eagle rays, schools of tuna and jacks, moray eels, angelfish, and other reef fish.
- Notes
- These are not inside the protected Cabo Blanco Absolute Natural Reserve itself (diving is not permitted inside the reserve boundary), but sites just outside it benefit from a documented 'spill-over' effect from the reserve's marine protection. Exact site locations/names are largely proprietary GPS marks kept by individual operators rather than being publicly documented sites.
Isla Cabuya Area
- Type
- Reef with a notable fan coral formation
- Best Season
- Not specifically documented; general regional dry-season visibility guidance applies
- Marine Life
- Abundant tropical reef fish; described by local divers as one of the richer fish-density spots on this stretch of coast due to proximity to the Cabo Blanco reserve.
- Notes
- Primarily referenced as a snorkeling/diving area rather than a single named dive site with a fixed profile.
Playa Los Suecos / Punta Murciélago
- Type
- Shallow reef and tide-pool area
- Best Season
- Year-round, tide-dependent
- Marine Life
- Stingrays, sea turtles, and typical shallow reef fish.
- Notes
- This is a snorkeling and shallow tide-pool spot rather than a true scuba site — included here because it's commonly listed alongside the area's dive offerings, but it is not where boat-based scuba trips are run.
Generic 'Rocky Pinnacle and Reef' and 'Underwater Wall' Sites
- Type
- Rocky pinnacles / reef systems / deeper walls
- Best Season
- Dry season for visibility; described as suited to more advanced divers when run as wall/deeper dives
- Marine Life
- Diverse reef fish, sharks, rays, and pelagics per operator descriptions
- Notes
- Referenced by at least one local tour operator as distinct site types on offer, but specific names/locations were not publicly documented in available sources — these appear to be unnamed or operator-proprietary sites rather than sites with established public names.
Seasonality
- Dry Season
- Roughly December to April/May — generally calmer seas and better visibility, considered more beginner-friendly.
- Green Season
- Roughly May to November — lower visibility but nutrient-rich water that increases overall marine activity and sightings.
Access Notes
- Dive boats launch from the fishing dock (Pescadería) in Malpaís for a short run to sites — one operator describes it as a "scenic 20-minute ride to the sites."
- Trips to Isla Tortuga are longer boat rides (commonly organized as a combined snorkel/dive + island day trip), on the order of 45 minutes each way from the Malpaís/Santa Teresa/Montezuma area.
- Cocos Island — Costa Rica's world-famous liveaboard-only site (sharks, pelagics) — is NOT reachable from Santa Teresa as a day trip; it requires a separate multi-day liveaboard departing from the Puntarenas area, and is a distinct trip from anything bookable locally in Santa Teresa.
- One older source claimed Malpaís/Santa Teresa had no local dive shop at all and that divers had to go to Montezuma, Tambor, or Curú instead; this appears outdated, since at least two dive centers (Iguana Divers, established 2014, and Ananda Dive N' Flow) currently operate directly out of Santa Teresa/Malpaís with active, recent customer reviews.
Courses And Operators
- Operator Density
- Dive operator density in Santa Teresa itself is low — this is a surf-first town, and the handful of dive/snorkel operators serving the area tend to be based in or shared with nearby Montezuma and Mal Pais rather than clustered in central Santa Teresa.
- Freediving Crossover
- No verified evidence of dive shops in Santa Teresa commonly offering structured freediving certification courses (e.g. AIDA/SSI) as a standard add-on. Freediving/spearfishing is culturally present on this coast informally (surfers and locals free-diving for fish), but this is not confirmed as an organized course offering tied to the scuba shops here.
- Typical Cost Open Water
- CRC 250,000
- Certification Availability
- Full PADI-style certification progression (Discover Scuba / Open Water / Advanced) is not a strong, established local specialty of Santa Teresa itself the way it is in Costa Rica's Pacific dive hubs (e.g. the Gulf of Papagayo or Caño Island area). Operators serving the Santa Teresa/Mal Pais/Montezuma stretch have historically offered PADI Open Water Diver courses and guided fun dives out to sites like the Cabo Blanco reserve waters and Isla Cabuya, but course availability, staffing, and even which shops are currently operating can change season to season.
- Advanced Or Divemaster Availability
- Advanced Open Water and Divemaster-level training is not reliably documented as a standing local offering in Santa Teresa proper; nomads wanting those levels more commonly travel to larger dive centers elsewhere on the Nicoya Peninsula or Pacific coast.
Typical Levels Offered
- Discover Scuba (intro/try-dive)
- PADI Open Water Diver
