Alien Divers

5.0(224 reviews)

Based in Ao Nang, Krabi, Alien Divers operates as a full-service scuba diving and tour agency catering to everyone from first-time divers to seasoned underwater explorers. The operation runs guided day trips to nearby islands and local dive sites, where visitors have encountered an impressive range of marine life including stingrays, barracudas, seahorses, banded sea kraits, lionfish, and eels. Family groups can combine diving and snorkelling on the same trip, making it a practical choice for mixed-ability groups travelling together. The atmosphere is consistently described by visitors as professional, organised, and safety-conscious, with instructors who are patient and experienced across all skill levels. Discover Scuba programmes give complete beginners a structured introduction to diving in open water, while more experienced divers can join fun dives at the surrounding island sites. The team speaks English and guides are well-regarded by name in visitor feedback, suggesting a personal and attentive approach to each group. The shop operates daily from 8:00 AM to 8:00 PM, offering flexibility for booking on arrival or planning ahead. Checking the website at aliendivers.com before visiting is worthwhile for current course schedules, trip availability, and any advance booking requirements. Certified divers should bring their dive certification cards, and all visitors should pack sun protection, as time on the water between dive sites can involve significant sun exposure.

Visitor Reviews

We had a wonderful time during our discover scuba dive with Garry and Nathan! We felt very safe and protected the entire time. It was our first time scuba diving, and we definitely want to go again! We saw a lot of beautiful fish and coral. Krabi and its surrounding islands seem like a great diving spot. The price was also very fair.

I had an incredible experience diving with alien diver, Ksundek . From start to finish, everything was perfectly organized and professional. The instructors were highly experienced, patient, and genuinely passionate about diving, which made me feel completely safe and confident underwater & take lots of photos

Great family day today with Alien divers to local islands. We did a mix of diving & snorkeling which was great. Saw rays, barracuda, lion fish, seahorses, banded seakrait, eels, hundreds of different fish, colourful coral, anemones, urchins. Great crew & would 100% recommend. Thanks

Tips for Visiting Activities & Tours

Vet Elephant Sanctuaries

Only visit sanctuaries that prohibit riding, use no chains or bullhooks, and let elephants roam freely. Elephant Nature Park in Chiang Mai set the standard. If a place offers painting shows or circus tricks, walk away.

Book Through Klook or GetYourGuide

These platforms offer instant confirmation, free cancellation on most activities, and prices that are often lower than walk-up rates. Compare with local agencies for multi-day trips where negotiation might save more.

Do Outdoor Activities in the Morning

Heat and humidity peak from noon to 3 PM. Schedule jungle treks, cycling tours, and outdoor cooking classes for early morning. Water activities are more flexible since you're in and out of the sea.
