Scuba Diving for Certified Divers in Costa Adeje
The best part of this Costa Adeje scuba trip is the freedom to visit different local sites rather than being tied to one fixed underwater spot. Travel Sub chooses the location according to weather and sea conditions, then takes you there by speedboat with an instructor close by. That can mean good visibility, plenty of sea life, and a more comfortable session for a mixed group.
I like the small maximum group of 10, though some sessions may be much smaller, and I like that the price includes the main equipment and boat trip. The staff have also handled refresher sessions for people returning after years away, which is useful. One thing to check first: a computer, insurance, photographs, and refreshments are not included, and a refresher is obligatory if you have not been underwater for more than six months.
Key points to know before booking

- Sites change with conditions: The crew selects the location based on weather, sea state, and expected visibility.
- Speedboat access: You travel from Costa Adeje to the chosen local site by boat rather than from shore.
- Small-group attention: The maximum is 10 people, with some outings using one instructor for only two participants.
- Recognized certifications accepted: BSAC, CMAS, PADI, and other licenses are accepted.
- Refresher support: If you have not been underwater for over six months, you must arrange a refresher session.
- Bring your certification details: A computer, insurance, photos, and refreshments cost extra or are your own responsibility.
Starting at Travel Sub in Costa Adeje

Your morning or afternoon begins at the PADI 5 Travel Sub Dive Center at Calle Colón, Escuela Nautica, in Costa Adeje. The activity lasts about two and a half hours and ends back at the same meeting point, which keeps the logistics simple.
You do not need to haul a full set of equipment across Tenerife. The package includes a tank, buoyancy control device, regulator, weights, fins, and wetsuit, along with the boat trip and an instructor. Bottled water is also provided.
The center is near public transportation, and confirmation arrives when you book. Service animals are allowed, and most people can participate, but certified status matters. This is not an introductory lesson for a first-time participant. You should arrive with a recognized qualification such as PADI, BSAC, or CMAS.
I would bring proof of certification and any personal equipment you prefer to use. One participant found the supplied wetsuit wet and cold, which is normal for a suit used between sessions but can feel unpleasant. If you own a suit that fits well, bringing it may make the equipment stage more comfortable.

Choosing the site by weather and sea conditions

Travel Sub does not promise one named site every day. Its weekly program uses several local locations, with the crew making the final choice according to the weather and water conditions. That is a sensible approach in Tenerife, since the best site depends on the day rather than on a fixed marketing promise.
For you, this means flexibility is part of the experience. You may visit a place known for strong marine life, or you may use a calmer site when conditions call for it. The aim is good visibility and a safe, enjoyable underwater session, not checking off one particular point on a map.
The boat ride is part of the appeal. A speedboat gets you away from the marina quickly and gives the outing a clear sense of purpose. One participant reported about 24-degree water, good visibility, a wide range of wildlife near the fish farms, and even a dolphin crossing the route. Those sightings cannot be guaranteed, but the local waters can provide more than just a basic training session.
The tradeoff is that the exact setting remains unknown until the crew assesses the day. If you need a specific site, a particular wreck, or a guaranteed animal encounter, this flexible format may not suit you. If you care more about safe conditions and a good chance of seeing marine life, the arrangement makes sense.
What happens on the boat and underwater
After equipment is prepared, you board the boat with your group and instructor. The crew gives a briefing before entering the water, covering the plan and the practical details for the session.
You should pay close attention to the entry instructions, especially if you have not been underwater for some time. One participant returning after a 10-year break took a refresher with instructor Julia before continuing. That extra step made the outing more suitable for someone whose certification was current but whose recent practice was limited.
At the entry point, you need to inflate your BCD before getting into the water so you can remain on the surface. After entering, follow your assigned instructor and stay with the planned group. This sounds basic, but it matters. A participant became separated while adjusting buoyancy and moving toward another instructor’s group, creating confusion at the start of the session.
You may use your own computer or rent one at reception. The computer is not included in the stated price, and the instructor uses a computer for the guided session. If you are accustomed to tracking your own depth and time, I would arrange a rental before departure rather than assuming one will be supplied.
The guide brings you back to the anchor line for the safety stop, then you return to the boat. The session finishes with the ride back to Costa Adeje and return of the equipment at the center. The outing is short enough to fit into a busy holiday day, but it still includes transport, preparation, the underwater portion, and the return.
How much personal attention can you expect?

The advertised maximum is 10 participants, which is reasonable for a guided boat session. The more useful detail is that some groups are much smaller. One outing had just two participants with instructor Guillermo, while another participant worked with Julia for a refresher.
A smaller group gives the instructor more room to watch your comfort, equipment, and position. It also helps if you are rebuilding confidence or need clear explanations. The center says multilingual groups are common, and briefings can involve several languages. English is offered for this activity, and Guillermo’s briefing was given in English for one English-speaking participant.
Communication still deserves your attention. Before entering the water, confirm the maximum depth, planned bottom time, safety-stop procedure, and how the group will stay together. If English is not your first language, ask the instructor to repeat anything unclear. A guided session is safer and more relaxed when everyone understands the same plan.
The staff have generally been described as friendly, organized, and safety-focused. The strongest praise goes to the crew’s calm manner, good equipment, and lack of ego. That matters in a setting where you want professional direction without feeling rushed or intimidated.

Equipment, wetsuits, and extra costs

The package covers the core kit:
- Tank
- BCD
- Regulator
- Weights
- Fins
- Wetsuit
- Boat transport
- Instructor
- Bottled water
That makes the $66.37 price fairly attractive for a guided boat session, especially if you do not own a full set of equipment. You are paying for more than tank rental. The fee also covers the boat, staff supervision, and access to a changing and equipment center.
The kit is described as good quality, and one participant specifically praised the organization and condition of the gear. Still, equipment is shared and wetsuits may be wet when handed to you. The center says suits are disinfected after every trip and dried in the sun, so a damp suit is not necessarily a cleanliness concern.
Several items are outside the price. You pay separately for insurance, photographs, refreshments, and a computer if you want to rent one. Bottled water is included, so bring any food or other drink you need for after the session.
Photography is worth clarifying before you leave. The center takes underwater photographs that you can view at the office and purchase if you want them. The photos are not automatically sent as previews, and you should ask about them at the center before departing. This avoids the problem of leaving first and trying to arrange the images later.
If you have not been underwater recently

Your certification alone does not tell the whole story. If you have not been underwater for more than six months, a refresher is obligatory. That rule is sensible, particularly for checking buoyancy, hand signals, regulator use, and entry procedures before you join a boat group.
The refresher can be a good use of time rather than an annoying delay. Julia led one returning participant through a refresher after a 10-year gap, and the session was described as enjoyable and well organized. If your last session was several years ago, tell the center when booking so the staff can plan properly.
If you are over 55, you need a medical reference. The supplied information does not state what form that reference must take, so ask Travel Sub before arrival. Do not leave this check until the day of the trip.
You should also be honest about your comfort with current, buoyancy, and boat entries. The crew can support a range of experience levels, but you still need to manage your own equipment and follow the guide’s instructions.
Marine life and what you might see

The local sites are chosen partly for visibility and marine life. One participant saw a broad mix of wildlife near the fish farms and a dolphin from the boat. That gives you a useful sense of the area’s possibilities without promising a fixed wildlife checklist.
I would treat the animals as a bonus, not the product. Sea conditions, site choice, and luck control what appears. The more reliable benefit is having a guide select a suitable location and lead the group through it.
The speedboat also gives you a chance to see more of the coast than a shore entry would. You may spend less time walking with equipment and more time getting to the selected site. The cost is a little less certainty about timing, since weather and the crew’s choice of site affect the day.
Safety, language, and group etiquette

Safety is one of the center’s strongest points. The guide remains with the group, leads the briefing, and brings everyone to the anchor line for the safety stop. One participant praised the instructor’s clear communication and careful attention to safety.
You should still take responsibility for the basics. Inflate your BCD before entering, stay with your assigned instructor, and signal promptly if you have trouble. If you need time to adjust buoyancy, tell the guide before moving away from the group.
Do not assume your instructor knows your preferred depth, breathing pace, or equipment habits. A short conversation before boarding can prevent confusion. This is especially important in a mixed-language group, where the staff may be switching between English, Spanish, and another language.
The maximum group size of 10 is not tiny, but the available small-group format can be excellent. If the number of participants matters to you, ask about the expected group size when you book rather than assuming every departure will have only two people.
Who gets the best value from this trip?
This outing is a good fit if you:
- Hold a recognized scuba qualification.
- Want a boat-based session from Costa Adeje.
- Prefer a site chosen for current sea and weather conditions.
- Need equipment supplied.
- Appreciate an instructor-led group rather than planning an independent outing.
- Want the option of additional sessions, including night trips.
- Have not dived recently but are willing to take a refresher.
It is less suitable if you want a first-ever scuba experience, a guaranteed named site, or a package with every extra included. It may also disappoint you if you expect dry wetsuits, a free underwater photo package, or a personal computer as standard.
The $66.37 price offers good value when you need the full basic kit and boat transport. Add the possible cost of a computer, insurance, photographs, and refreshments when comparing it with other Costa Adeje options. A low headline price can change once extras are added.
Cancellation is straightforward: you can receive a full refund if you cancel at least 24 hours before the local start time. Changes or cancellations inside that window are not accepted for a refund.
Should you book the Costa Adeje session?
I would book this trip if you are already certified, want a professionally guided boat outing, and are happy to let the crew choose the site. The strongest reasons are the flexible site planning, included equipment, speedboat access, and the chance of close instructor attention in a small group.
Before paying, confirm four things: your certification is accepted, you meet the six-month refresher rule, you know what insurance is required, and you understand the extra cost for a computer or photographs. Ask about the likely group size and mention any language or equipment concerns.
For a confident certified participant, this is a practical way to get back into Tenerife’s water without arranging a private charter. For someone returning after a long break, add the refresher and treat the briefing as part of the experience, not a formality.
