About this tour
When Alex from our team hit the water in Tenerife's volcanic bay, the underwater scene was genuinely striking — jagged lava formations jutting up from the seafloor, schools of fish weaving through the rocks, and the occasional cuttlefish doing its colour-change thing. The 1h 45m tour keeps things manageable: boat transfer to the bay, 90 minutes in the water with a guide, and you're back on dry land. It's a straightforward snorkel, not a deep-dive expedition, which suits most swimmers after a bit of instruction.
Highlights
- Volcanic rock formations create an otherworldly underwater landscape
- Starfish, crabs, cuttlefish, and prolific fish species throughout the bay
- Guided snorkel means you're not flying blind with an unfamiliar site
- Wetsuit, mask, fins all supplied — minimal gear faff
- Digital photo set sent after the tour as a keepsake
- Boat transfers you directly; no long swims to the site
- Suitable for ages 8+ who can swim confidently
What to expect
The morning starts with a boat ride to a sheltered volcanic bay — the water's surprisingly clear and the bay feels contained enough that you don't feel adrift. Your instructor gathers everyone, checks kit, and walks you through basics before dropping in. Once underwater, the geology dominates: sharp, dark lava formations create little canyons and ledges where marine life clusters. You'll spot plenty of reef fish, the occasional crab poking from crevices, and if you're patient, a cuttlefish or two. The pacing is leisurely — your guide points things out but isn't rushing between dive sites.
What surprised Alex was how much the volcanic rock actually shapes the experience. It's not a coral reef, so the energy feels different — more geological, less colourful — but that's the trade-off with a lava-formed coastline. Water temperature is mild enough that the provided wetsuit keeps you comfortable. The return boat ride is brief, and they hand over a digital photo pack afterwards, which beats trying to operate a camera in a mask.

Good to know
This is ideal for first-time snorkellers or swimmers wanting an easy introduction to Tenerife's underwater scene. The volcanic formations are genuinely unique and photo-worthy. Gear is included, so you're not hiring or buying separately. Small groups mean the guide can actually keep tabs on everyone. Kids aged 8+ who swim can join, making it a solid family option.
You're dependent on decent weather — rough seas or poor visibility could scupper your day. The 1h 45m slot is short if you're hoping to explore extensively; it's more of a taste than an immersion. Swimming ability is non-negotiable; non-swimmers won't be accommodated. Video recording isn't included, so if you want professional footage, expect to pay extra. The bay itself is popular, so don't expect solitude. Bring a towel and your own swimsuit; nothing fancy needed, just functional. Public transport is nearby if you're not driving.
