Full description

This is a 3-hour experience in Krabi. It is run by GR Rungtawan Co., LTD., an operator we book with directly rather than through a reseller, which is why we can hold your place with them before we treat your booking as final.

Nagoya is Japan's fourth city and the gateway to the Ghibli Park at Nagakute, opened in 2022 with timed tickets that sell out weeks ahead, to Nagashima Spa Land and its rollercoasters, and to Inuyama, whose castle is one of the twelve original keeps. Nagoya Castle's golden dolphins and the Toyota Commemorative Museum are the city's own sights, and hitsumabushi grilled eel and miso katsu are its food. The Ise Grand Shrine, Shinto's most sacred site, rebuilt every twenty years, is 90 minutes south.

The price covers Sandwich, Juice, Fresh fruits, Bottled drinking water and Life jacket. It does not cover Fins, Dry bags and Personal expenses, so budget for those separately. Everything included is listed in full on this page; if something is not on that list, assume it is not in the price.

We need at least one day's notice, and we confirm the date with GR Rungtawan Co., LTD. before treating your booking as final.

It was good but expected to see the bioluminescence effect on the plankton. That was missing

Amazing long boat trip to Railay Beach to swim, see the limestone cliffs, caves, beautiful sunset and then on to the bioluminescent plankton. Definitely worth doing!

Our tour guide Maya was excellent and kept the whole trip fun and informative. It was a great opportunity to spend time at Railay beach and to watch the sunset. The plankton swim was incredible and very cool! Highly recommend!

el plancton no existía, vimos 3 luces pequeñas y nada parecido a las fotos y videos. una gran desilusión. el barco muy ruidoso y no se veía nada para afuera, parecía una cueva. y el guía hablaba muy mal, no le entendimos casi nada. mala experiencia.

Es ist nur eine absoluten Massenabfertigung! Alles ganz hektisch alles muss ganz schnell gehen. Man hat keine Zeit Fotos zu machen oder sonst irgendetwas. Rausgeschmissenes Geld. Lieber 100 Baht ausgeben für den Transfer und gut ist. Dann hat man auch genug Zeit für sich selbst und um die schöne Aussicht zu genießen.

The boat ride was very rough and you got very wet in the boat. We were just dropped off at a beach and left to do our own thing and given a time to be back at the boat for. Then it was another very rough boat ride back to where the trip started to see the bioluminescent plankton that was extremely hard to see - it could’ve just been your brain playing tricks on you. Definitely not worth the price!

This was a scary experience. The weather conditions were rough and the boat felt very unsafe, rolling side to side. Another guest took videos of our faces the entire trip without permission. The Railay beach itself is nice. We blindly followed the guide without much directions or information about the place. You stay on Railay for about 1 hour. I would consider the boat ride back a near death experience on this occasion. The plankton was underwhelming. Another boat crashed into ours whilst trying to get a spot. The plankton was scooped up in buckets and splashed over the boat deck, including o

Railay beach was beautiful and lovely to visit at sunset as not as hot and assume less busy. We took a long tail boat rather than ferry but it was a wonderful way of travelling. The plankton were a little underwhelming but this was apparently due to a full moon

Such an incredible experience. Our guide was fantastic, kind, and helpful. The boat ride is beautiful. Don’t be shy, sit at the front! Railay beach was beautiful. The sunset was gorgeous. We wish we didn’t eat before the tour because there was endless food at Railay. Swimming with plankton was magical to see and experience. Would absolutely do it again.

Realmente no hicimos snorkel, ni nos dimos un baño ni nada de lo que pone; en definitiva fue un transporte a Railay.Considero que cuando el tiempo no acompaña para una actividad deberían cancelarla. No es culpa de la guía, tanto ella como el señor que llevaban el barco eran muy majos pero lo hicimos la actividad que venden. El plancton fue un total de 5 minutos verlo, no de lejos como se vende.
