This is one of the most amazing caves that I have seen. It doesn’t have the most beautiful stalagmites or stalactites, it is the size that puts me at awe. Song Hong is about 120km drive from Krabi, the nearest town to Song Hong cave would be Thung Yai.

Song Hong lake is only about 75 meters across and 75 meters wide. In the middle of the lake you can reach max depth of 100m.  I have managed to get down to about 155m meters in the cave a couple times. There have been other teams that have bottomed the cave out at 178m.

Both inside the cave and in the lake you will find survey lines between the depths of 10 m to 60m going all around the lake and cave. There are some other lines that are being laid at the moment down around 80 and 100m.  In the shallows there is a orange line that has been laid to let you know that you are in the cavern zone. You will also see lines that follow the wall down to the bottom. At 6 m one of the local dive centers had installed a habitat, just at the entrance of the cave. They did a excellent job of installing the habitat as it has been there about 3 years already.

In the shallows the viz is not the best in the world, however when you reach about 30m the Viz can actually get to be about 20 meters. Sometimes you have better viz inside the cave then you do outside. When you go inside the cave entrance it is amazing because you cannot see any of the other walls because the distance is to far to see.

How to get there:-

Directions to Song Hong – Take 4 going east . Go past the airport til you get to 4037 then turn left. Drive till you reach 4156 and make a right turn. Drive 39 km and this will take you to a hotel called Burilamplai on the right hand side of the road. This is where most cave divers will stay. They can be contacted at this information.

To get to Song Hong from the hotel make a right on 4156 and drive to 4038. Head down 4038 until you see a yellow school bus stop on the left side. It is exactly 12.9 km once you get on 4038. Turn left and drive 3 km until you come to a T junction . Turn right at the T junction and drive 4 7/10 km . There will be a road turning to the right and a market there on the corner. Turn right before the road to the right, there is a car path leading back to Song Hong. Probable the nearest place to get tanks filled would be the One Stop Shop near Ao-Nang. (Highly recommended that you bring your own tanks and compressors if you plan to stay a couple days or more.)

map_srikaew_cave_thailandThis is the deepest cave that I know of and have dove in Thailand. This cave looks like a small pond but what you do not know is that small entrance will take you a long ways in. I have made numerous trips down to this cave on different occasions. There are two ponds that you can see and they will both join up at about 80 meters depth. The first pond you come to has the best viz of the two. Be careful when you go because the viz can turn real bad and real quick.

The second pond there is what looks like to be training lines all over the place. Every time I went in this pond the viz was lousy right from start. The viz does get good once you get past the 80 m mark to where it actually gets quite clear. This must have something to do with the rain and the mountains surrounding the caves.

cave diving exploration trips thailandOn numerous trips I helped other team members by staging tanks down to the 120 meter depth range. Some of the divers had gone down to 150 m on one trip and 200 m the next. One time I had to be the clean up diver hitting the surface with 8 tanks clipped on. That was fun right up to the 20 m mark where there was a line trap (the line has been moved so there is no more line trap) and had to try and navigate around .This cave bottoms out at 240 m. A group of guys living in Thailand had gone and bottomed out the cave on one trip. Around the back side of Sre Keow if you follow the small road around you will come across a small pond on the left hand side hidden back in the trees.

The viz was not so good but if you follow the line that is already laid you will come up to a small restriction at 20m Just about big enough to squeeze through with a set of twins. Once you get through this passage way the cave goes down at about 45 degree angle I have down to only 40 meters or so but have been told that it goes beyond 90 m. This passageway is at an angle heading right towards the main cave system out front.

How to get there:-

Take 4203 which is just north of Ao-Nang Thailand heading east. Make a left on 4033 and go approximately 1 ½ km then turn right on 1003. Drive about 3/10 km and turn right on a small road leading to a elephant farm. You will drive 1 4/10 km down this road and turn left. You will turn left right before the road turns into a dirt road. This road will take you to the two main ponds of  Sre keow.

Thong Pha Phum Cave

tong_paa_phum cave exploration thailandLocation: Thong Pha Phum, Kanchanaburi, Thailand
Depth: 0 – 60m/200ft

Thong Pha Phum – located about 120 km north of Kanchanaburi. This is where I first started searching for caves, I think I have come across about 6 different caverns and two very nice caves.

The first cave that I dove in up north was when a Thai policeman took me up there to show me its location. It was a beautiful 40 minute long tail boat ride. When you arrive you will just see a small island in the middle of this lake.

If you scale down the one wall you will find the entrance. Going straight will take you through the cavern and right out the other side.

A great place to take cavern students for their first cavern dive. Safe and easy to navigate.

tong_paa_phum_stalactite1-224x300There is a nice passage that follows the left wall around that will either take you outside or turn right and take you to the main passageway through the middle. In this cave I have seen schools of baby cat fish and also some of the biggest catfish alive. The biggest catfish was about 1 ½ meters long.

This fish definitely was not scared of me, he kept staring at me and never swam away. The bottom depth of this cave is around 15-18 meters. This is hard to judge sometimes since the water level varies a lot during the year.

Not far from the village where we leave from are two other caverns. The one cavern is one of my favorites since there are a lot of turn and boulders in there that make good practice for the students practicing laying lines. The cavern gives you the feeling like you are way back in a big cave system but if you look close you can see the light from the entrance. During the low level water season someone had parked a small boat inside. The water had risen and the boat was left in there.

p1030799-300x224To our surprise we looked up and there was this boat inside the cavern. Just around the corner from this cavern is another one.

Nothing spectacular but a descent place to dive and practice skills. I believe these two caverns do connect somewhere in the middle. I have not been able to connect them up as of yet since I am normally with students when I go.

One of these days I will take my OMS side mount kit and see if they really do connect. Not far from a floating restaurant there are a bunch of caves along this big tall mountain wall.

Thailand Cave Diving CoursesTwo caves there really stick out in my head. One of them the entrance is not very deep maybe 6 meters or so. When you enter you turn to the left and follow the wall.

Once you get in there are a couple different directions that you could go. There is a nice passageway you follow with spots all over the wall. IF you do go the other way there are places that you can poke your head up out of the water.

There is one place you can actually get up and take your equipment off. I never did but there was a passage way going somewhere. The viz in this cave is totally awesome, never been there with bad viz.


There are some permanent lines laid in this cave with some jumps put in for the students to practice with. Not far from this cave is another island that has a real descent cave.

Once laid out more than a whole reel and it kept going back in. Stupid me reeled out and have not been able to find the passageway again which is somewhere against the back wall.

cave diving expeditions thailandI have been told that there is a large Buddha image still left in this cave. I did find a large wooden table in the middle of the cave.

This table was used to put Buddha images and such when they come to the cave. This lake is all fresh water.

The whole area used to be dry until they built the dams about 30 years ago and flooded the whole town. This same cave the viz can get quite low however I like this cave the most and give the student some excellent training. I did lay some primary lines through the cave but they probable should be re-laid.

How to get there:-

Directions to Thong Pha phum – Take 323 out of Kanchanburi . approximately 130 km north of kanchanaburi.

You do need a long tail to get to the caves. Caves range from a 10 minute boat ride to 1 hour. Excellent boat ride getting there.

30 meter cave – 14.54.722 North 98.31.054 East

Depth got to be 30 m, great for training, can have very low viz, there is a wooden table inside where the people would put Buddha images on before the flood. This cave is a traverse. I did lay some lines through the cave but after diving a couple times I thought they could be laid much better. First time through you have no ideal where to go.

Long Cave – 14.57.180 North 98.29.289 East

Shallow cave with some awesome visibility. I laid some lines through and set up some jump s for students to practice on plus there were other passages there. Very nice tunnel with spots on the walls as you get near the end. There are places inside this cave that you can surface and even get out of the water. You can spend a hour playing around in this cave and have a lot of fun. The cave entrance is directly across from a floating huts.

2 Caves – 14.56.792 North 98.29.504 East

Bat Cave 14.51.988 North 98.29.429 East

I wrote down nick-names for the caves trying to remember why I named them that. Been awhile since I have been up there.

dsc00057-300x224Khao Sok National park (Rachabrappha Dam) – This again is a fresh water lake. Probable the most well known cave in the lake is Temple cave. We dove this cave for the first time back in 2006. I think everybody and there brother has been in here.

There are about 3 or 4 places that you can enter into this cave. This cave is probable the most beautiful cave I have seen in Thailand. If you dive the shallow sections of the cave is awesome to be able to see all of the stalactites.

This cave is good for doing training courses in. We have actually laid lines at different levels of the cave allowing the students more to see.

dsc00202The max depth of this cave is around 24 meters, Again this can change with the time of the year. Not far from Temple cave is Peters cave.

Not sure who was the first one to dive this cave, it might have been either Erik or Milo.

The cave entrance is quite shallow maybe 6 meters or so. There is a primary line laid all the way around this cave. The max depth may be right around 15-18 meters.

There is a second entrance to this cave which I like to use for training of restrictions. Down and off to the left of the main entrance is a second entrance.

You can barely squeeze through with a set of twins on, if you have a deco tank you will probably have to take it off and shove it through the whole. One you go inside after about 10 meters it will go to the left. There is a nice restriction that you have to go through and it will come out right in the bottom of Peters cave. This I like to do blacked out mask, out of air and touch contact.

p6230110-300x224Nam Dang is another place for training. Probable best for doing the first couple dives of the cavern course. Easy and safe to dive.

I like to get people to practice laying line through here where if they make a mistake they can easily get out. You can see the entrance most of the way around the cave. There is one small whole that Peter showed me and he said that it went up and in a good ways. I was playing around to see if I could fit through the whole with my rebreather on.

Actually had my 02 valve roll shit , wondering why my po2 was getting low. Lol. I believe there are good possibilities of finding more caverns and caves in this lake. I know a lot of the guys from the south have been always checking out new spots.

How to get there:-

Directions to Khao Sok National Park – 41 to 401 Head west on 401. Drive till the village Ban Ta khun. There is a sign that says Ratchaprapha dam. Turn left and drive about 13 km and the road will come to a T. Turn left at the T and go through the guard shack. Once through the guard shack make a immediate right and this road will take you to the main pier

Phi Phi

Many moons ago I did my cavern course on Phi Phi with Matt London. We did dive in a cave called Maia cave or something like that. Actually thought it was a good cavern to dive it. This cavern is right near the beach where they filmed the movie ‘The Beach‘ , There are some sea caves down off of PHI PHI that I have not had the chance to dive in. I have been told that they go in about 120 m or so. Hopefully I will get the opportunity to dive these caves in the near future…
