36 tours  ·  from $28 a head

The water only glows on a dark night, so the moon matters more than the boat. These 15 compare the sunset-and-swim runs against the pure night trips, with prices, what dinner is, and how long you get in the water.

9.Krabi 7 Islands Snorkeling & Plankton Night by Big Longtail Boat

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

Review of Krabi’s seven-island longtail tour, with snorkeling, sunset barbecue, sandbars, 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 $35

Review of Phi Phi’s 8-hour island tour with Maya Bay, Shark Point, Bamboo Island, sunset, and bioluminescent plankton for $35.

“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”

Krabi: Railay Sunset and Bioluminescent Plankton Tour

13.Railay Sunset and Bioluminescent Plankton Tour

★★★★★★★★★★3.9 · 55 reviews · 3 hours - 210 minutes · from $31

Watch Railay’s sunset, swim in the Andaman Sea, and search for glowing plankton on a budget-friendly longtail boat tour from Ao Nang.

“Everything was very rushed and we left about 30min late due to some late passengers. The boat look ok but the steps are not safe and the guy supposedly helping people in and out was not that bothered. I ended up slipping and hurting my foot and not even an apology or a "are you ok?". Railay is obviously nice but too crowded with boats and people and the planktom is hit and miss. There are many others beached in thailand and even in Krabi that will be better”

Other than the drop off situation we had a good time”
