Exploring the beauty of Cheow Larn Lake - a must do in the area. - We had a wonderful full day tour to Cheow Larn Lake. We chose a small group tour and there were only 6 of us, so that was even better!
We started off with a coffee stop before we arrived at Headwater Forest and could enjoy some time in the water at Nam Rad Watershed Creek. Then it was off to the dam!
The port was busy, but we had our own longtail and our brilliant guide paid for our national park fees and led us to our boat. Then it was off to explore the reservoir. Such beautiful scenery and the limestone karstes are stunning. We were very lucky with the weather and we loved the lunch stop at Khao Sok Smiley Lakehouse. Delicious food and my gluten free needs were taken care of.
There was a chance for a swim and some relaxation time, then we continued our journey to the caves where our fabulous guide explained the history and showed us the best parts of the cave system. We were lucky enough to be the only group there at the time.
We then headed back to the port, boarded our mini bus and had 1 last stop at the dam viewpoint before heading back to our hotel. A long, but great day!

Excellent day out! - An amazing day with different activities along the way. We swam in crystal clear waters where the fishes were beautiful, there were also otters playing on the banks so close to you. Word of advice the rocks getting in and out of the water are really slippery so be careful, beach shoes would be recommended for gripping.
The long boat ride was amazing the scenery is just stunning. Food on the island was great and all the people so friendly.
When you visit the caves beware again of the slippery floor. This is our only criticism of the trip that there isn’t a better indication of things to bring with you for activities or recommendations for footwear and flip flops were certainly not ideal for everything!
That said we really enjoyed ourselves thank you Mone and Keng for being our guide and driver for the day!

What a great day out..., - Grace was our guide for the day & was extremely friendly, informative & well prepared, applying anti septic cream to my husband's leg when he experienced a collapsed plank after lunch on a rotting pontoon. First up was a coffee stop followed by an escorted kayaking trip & a swim along the river. A rather friendly otter was nibbling at my husband's water shoes after his swim. We then took a longboat across the lake, visiting a cave and then stopped on an island in the middle of the lake for a lovely Thai lunch. The day was completed with a swim in the lake. The lake was stunning and the excursion was a brilliant day out.

An excellent day from start to finish, visiting some of the most beautiful sites in & around Khao Sok national park 🙏 - We had the best day visiting Khao Sok National park. From pick up to drop off it was amazing. We visited a beautiful emerald pool along the way & saw some of the most breath taking views we’ve ever seen. Lunch was included & was delicious & our guide JoJo was brilliant & I would highly recommend this trip to anyone visiting Khao Lak

Had a great day. Khao... - Had a great day. Khao Sok National park nature reserve was lovely. We took a kayak along the Sok river which was very peaceful.visited the Prakkai Petch Cave or Diamond cave. Not ideal if you dont like inclosed spaces and the climb up was difficult. Swam in the creek, very slippery, so take care. Lunch at Watershed was good. Overall a good trip.

Avoid this trip. They cancel on you - Booked this two days ago. They took my money today and then an hour later cancelled the trip. I see from the reviews that this isn’t the only time they have done this. Very deceitful and disappointing. The reason they gave was that it was fully booked but surely that was the case when I booked. They did offer another date but we will have left by then. Would they then cancel that date. Avoid this company. Should here heeded the previous reviews. They now have my money for the next few days and hopefully I will get it back without a fuss a as somebody else has a problem.

book with caution - We booked this tour 4-5 days before it was scheduled. Two days before, they emailed to say that the tour we booked (which stated there was availability) was already full and they did not have availability until three days after the booked tour. I called the listed number and they confirmed this was the case. They asked if we could switch to the next available date, which we could not as we would be leaving the country. They then said they would cancel our tour and refund us, with no apology for having taken upwards of 250 USD for a service they did not intend to provide. By this time it was too late to book a different tour. They did not attempt to refund us that day or the next, despite multiple requests. It was not until later after contacting Viator directly that the refund process started. Book with caution.
