2.7 Islands Sunset Tour with Plankton Swim and BBQ

★★★★★★★★★★4.0 · 808 reviews · 7 hours · from $49

Review of Krabi’s 7 Islands Sunset Tour, with snorkeling, beach BBQ, sunset views, hotel transfers, and a chance to see glowing plankton.

“The activity was good. Sunset was amazing, dinner was delicious served at the beach. We saw also some plankton. What ruined my experience was the driver of our transfer back to the hotel. He was insanely driving an open car with 8 passengers, we were without seat belts. The travel was very dangerous and the local tour agency needs to take strict measures to avoid similar cases in the future that out in danger the life of the tourists. The plate number of the vehicle was WU 4987. Avoid it!!”

Review of Krabi’s 4-Island Sunset Cruise, with snorkeling, Thai dinner, paddleboards, sunset views, and a bioluminescent night swim.

“We had a wonderful time. Michael and all the guides were friendly and fun. We had food and beverages and were very comfortable. There’s a lot of shady sections and some sunny ones. It was pricier than some other options but like the other reviews state, well worth it. Michael sent us photos and videos of the day - an extra bonus. We also saw a couple of sharks and a creepy snake!”

★★★★★★★★★★4.0 · 164 reviews · from $52

Review of Krabi’s 7-island longtail boat tour with snorkeling, sunset barbecue, hotel transfers, and glowing plankton at night.

“We spent majority of the time on the boats, some sports couldn't snorkel due to wind and waves, some spots couldn't go too close to the reef because of sea urchins, buffet isn't at a restaurant it was pre-prepared food taken to one of the chalets on the island, restrooms were extremely unsanitary and weren't able to see the luminescent plankton because of the full moon. Other than that, it was magical, the guides were great, we got soaked because we sat right in front of the boat which was loads of fun, swimming with fish and snorkeling was awesome, the islands and the sunset was magical and the photos…”

★★★★★★★★★★3.9 · 101 reviews · 8 hours · from $35Best value

Review of Phi Phi’s $35 island tour, with Maya Bay, sharks, Bamboo Island, sunset, and plankton, plus practical tips and honest drawbacks.

“Die ersten Spots waren ganz gut,Monkey Island total voll ,womit zu rechnen war. Dann musste man sich entscheiden ob man Maja Bay besuchen oder tauchen mit den Haien!Eigentlich wollte man ja beides sehen wollen,man hat ja bezahlt dafür.Das war Mist!! Und vom Plankton war gar nicht mehr die Rede. Es wurde kurz auf offener See angehalten und den Sonnenuntergang abgewartet. FAZIT:Ersten Teil gut und dann ging es abwärts”

★★★★★★★★★★4.4 · 61 reviews · 8 hours · from $83

Review of the Phi Phi and Four Islands sunset tour from Krabi, with Maya Bay, snorkeling, BBQ dinner, and bioluminescent plankton.

“EPOPEA ALLE PHI PHI Il tour non vale il prezzo! abbiamo trascorso la maggior parte del tempo sulla barca per i vari trasferimenti. Diciamo che il vento non ha giocato a nostro favore e pertanto Maya Bay non è stata fatta, un paio di snorkeling di appena 30 min in cui abbiamo visto pochissimi pesci, la descrizione riporta cena al tramonto ma in realtà non è stato così. un semplice buffet sulla spiaggia e poi tramonto in barca. bioluminescenza...il nulla. e poi...troppe troppe barche ovunque. da non rifare assolutamente”

★★★★★★★★★★3.5 · 24 reviews · from $100

Review of Cartagena’s 5-island boat tour, with snorkeling, Playa Blanca, Bocachica, sunset in Barú, and nighttime bioluminescent plankton.

“At first we left late, and we had to take away recreational time at the Fort and add it to Playa Blanca (where they left us for several hours, but I'll explain that later). They called us at 7 am claiming that they would only tolerate a few minutes of delay (a schedule that we respected) and we ended up leaving on the excursion an hour and a half later (maybe more). They asked us for 20,000 more Colombians that WERE NOT SPECIFIED anywhere (understandable, but they should have told us). For the time of the plankton, they left us 3 hours in Playa Blanca (it's beautiful anyway, but I…”

Review of Krabi’s 7-island sunset tour, with snorkeling, beach barbecue, hotel transfers, and a bioluminescent plankton swim.

“The agency is totally fraud. The same tickets are available at one third the price directly at counters. Also they didn't even send a proper a/c minivan but a small truck to pick us from hotel. The food was below par. Luckily, the beauty of Krabi saved the day. I demand a refund for the trip.”

Review of Krabi’s 7 Islands sunset tour with snorkeling, halal BBQ, remote beaches, and bioluminescent plankton for $41.

“La zona per vedere il plancton non è la migliore piena di barche e luci e infatti non abbiamo visto niente. Poi siamo tornati ad ao Nang e ci hanno detto che non c erano taxi e ci hanno lasciato qua senza il rientro in hotel anche se da pacchetto era segnato. La cena al tramonto non era al tramonto ma alle 16.30. Ho fatto decisamente escursioni migliori Non la consiglio.”
