Great opportunity to view two uniquely different caves in a day - If you only have a full day in Phong Nga this is a great way to spend it, if you have longer this is a great introduction to 2 incredible cave systems. The tour - Phong Nga Cave & Paradise Cave Day Tour by Phongnga Discovery was great, ran to plan from pick up to drop off. Starting at Paradise Cave (a dry cave) from the drop off point there’s a walk up to the entry point of the cave and then you descend into the interior for about 1 km. The Amphitheatres up to 80 metres high and 120 metre wide were great as were the enormous stalactites and stalagmites, incredible size, shape and configuration. Plenty of time to walk in and out with out rushing, next stop a generous Traditional Vietnamese lunch then back into town for the 30 min Dragon Boat ride to Phong Nha Cave (wet / river cave). The boat travels into the cave about 1 km then back out to a point to allow you to exit the cave through more incredible stalactites with a 300 metre walk in cave, the boat trip up into the cave was great, limited noise and just a million years of rock formation, the walk was equally impressive with massive stalactites and stalagmites, formed in incredible shapes and configuration. Very enjoyable day suitable for a wide range of ages our tour ranged from 12 to 60 something. A couple of days later we followed this up with the Kayak - Hiking - Swimming Tour with Phong Nga - Ke Bang Tourism centre which allows you to go a bit deeper (in the dark with headlamps, do some rock hoping and swim in the fresh cool cave water, highly recommend if you have another day. Take your photos the first day and enjoy the surrounding nature and quiet the second with only limited addition snaps required.
