Nature Reserve Namtok Huai Yang National Park
You can take the motorbike to the national park and walk around in the jungle. There you can see wild monkeys, perhaps a snake in the trees, but best of all swim with the fish by the waterfalls.
You can take the saleng to Thap Sakae, a small city, and visit the café filled with yummy cakes. It is an adventurous way getting there. It varies between jungle, beach view and country road. There is also a big temple along the way.
Koh Talu is a paradise island that you have to visit. There are package tours to book. You take a taxi one hour south. There they serve breakfast. Then you will take a speedboat to an island and swap over to a snorkel boat. You snorkel at one place by a cave first and then you move on to another place. After that you go to Koh Talu and get a lunch buffet. The sand is completely white. You can stay in a bungalow overnight or return back with the crew. On the island there are turtles that you can visit.
Hua Hin - Black Mountain and shopping
The three largest cities in Thailand are Bangkok, Phuket and Hua Hin. Hua Hin is about one and a half hour north with taxi. You can go there by train as well. Close to Hua Hin there are two waterparks. If you would like to make an outing for the day you can take a taxi to Black Mountain, one of the waterparks, then continue to the big shopping mall Market Village in Hua Hin and finalize the day at the evening market by the mountains in Burma. You can visit this city many times or stay for a couple of days, because there are many things to discover.
Most people that go to Huay Yang fly to Bangkok. Since the trip is quite long it is nice to stay in Bangkok one or several nights before or after the journey. Bangkok has a lot to offer, from beautiful temples to diverse shopping. You can try different kinds of food, for example crocodile. You can get a good price for very fancy hotels and feel extra luxurious. There are expensive brand stores but also cheap markets. The traffic is hectic and many people try a ride with a tuk-tuk, but there is also a skytrain above ground that makes access to the city easy and there are also walking paths above ground to reduce the traffic noise.
Mini Trips - there are lots of excursions to make from Huay Yang, these are just a few samples.
