Wonderful Day on Cheow Lan Lake! - Wonderful day on the beautiful Cheow Lan Lake! Our guide, Khun Gae, was the perfect host and made the day go smoothly. The lake is simply stunning (though we were lucky with the weather) and the Emerald Pool is a delight (we recommend a 20-min kayak ride). Excellent value for money.

The view was amazing. - The Emerald Pool was not as big as you might think, but the water was crystal clear and beautiful. Unfortunately, I didn't find any otters. I enjoyed the view on Lake Turan and the activities in Sap. The guides were happy to talk to their guests and were concerned that they were having fun throughout.

Fantastic experience - We booked a trip to Koh Sok National Park and transfer from the airport to the hotel at Khaolak Planner. A really good trip with a skilled guide, cute drivers and very friendly staff at the office - all delivered a fantastic service. You get my warmest recommendations.

Amazing - It was amazing. The places you see & our tourguide Gay was also very nice and made the tour complete. We lost our shoes at the khao sok lake restaurant, they even went to find it and send it to our address. Thanks!

Cheow lan lake is so profoundly amazing - Cheow lan lake was spectacular! The emerald pool was okay - we were underwhelmed with it originally until an otter and huge fish joined our group in the water which was very cool, followed by monkeys having a grand old time on our way walking out. The little fish in the emerald pool nip at you so just be prepared. Cheow lan lake though was SO AWESOME. The long tail boat ride on the lake plus the island where we ate lunch and swam was worth the entire tour price. The company that led the tour - driver and guide were all fantastic too. Would go through this company again in the future when in Thailand.

Stunning scenery, terrifying journey there and back in the minivan. - We had a fantastic day, with beautiful scenery, especially from the long tail boat. Grace, our guide was good, although it did all feel a little rushed. We saw three wild elephants on the drive there and an otter and monkeys at the Emerald Pool, which was amazing. Our only negative was the drive there and back, which was two hours each way. The driver was borderline reckless and we felt very unsafe. He overtook every other vehicle on the road, even on blind bends and the brows of hills. Some of the time he was going over double the speed limit and when the vehicle was beeping to tell him he was going over the speed limit , he just accelerated! We have been in many vehicles in Thailand, and this one is the only one where the drive was dangerous.
