Just outside of downtown Kanchanaburi you will find one of the most famous national parks in Thailand — Erawan National Park. There, you can marvel at the famous Erawan Falls, trek in the forest, splash around in the water, and spot some wild monkeys.
5. Khao Sok National Park

Khao Sok National Park has the oldest evergreen rainforest in the world, huge limestone mountains, deep valleys, breathtaking lakes, and wild animals.
There, you can feed and bathe elephants, explore the mysterious maze of channels in the mangrove forest, take a long-tail boat to explore Cheow Larn Lake, and embark on a gentle trek in the jungle.
Less Crowding and Cost
The heat and humidity keep many people from traveling around Thailand in June. This results in discounted rates and quiet attractions, which makes June a great time to visit Thailand for the aspects of price and crowding.
What to Wear in June
Pack light and cool clothing with quick-dry fabrics. Be sure to pack a lightweight raincoat or umbrella and bring along some rubber boots as well as sandals if you want to keep your feet dry. UV levels will be high, so pack plenty of sun cream, a sunhat, and good sunglasses. Don't forget your insect/mosquito repellent.
For women, remember to bring long sleeves as well as a long skirt, trousers, or sarong with you if you are going to visit any temples. Men should also wear long sleeves and trousers in temples.
