Somewhat outside of the town Cha-Am is one of the several Somdet Ya parks (สวนสมเด็จย่าฯ) which exist around Thailand. In fact, there are at least three kinds of parks named after the mother of HM King Bhumipol. The first one is the historical park in Khlong San district of Bangkok around the birthplace of the princess mother - a place I plan to feature here later as well. Then there are several recreational parks named after her, for example the one in Nonthaburi province near Mueang Thong Thani. The one in Cha-Am district is of another kind, an educational park. The full name is สวนสมเด็จพระศรีนครินทราบรมราชชนนี, Suan Somdet Srinagarindra Boromarajajonani, the full ceremonial name of the princess mother, and is operated by the Chaipattana Foundation.
The park is located between Cha-Am and Hua Hin, west of the Phetkasem highway bypass on road 1001 leading towards the Springfield Village resort. Directly before the Huai Ta Paet reservoir the large sign "Welcome to Suan Somdet Ya" is nearly impossible to miss, there turn to the right and maybe 50 meters inside that road is the entrance. The area has just now become visible in hires in Google Earth, which will come into the WikiMapia view of the place soon as well.
Both days we stayed near there I have seen several buses parking at the entrance, bringing school kids to the park. Inside the park it has several outdoor school rooms - open huts with lots of chairs. And it is probably this way to get most of this park, as there are hardly any descriptive signs on the exhibits, so without a guided tour one hardly gets anything from this park. Only within the herbs garden it has signs with the names of the plants, and their medic effects. The fields with various vegetables or fruits grown for either display or agricultural techniques or for experimentation come without any signs, so I can only suspect it is these two purposes of them. If looking for scenic places within the park it is really not the place to go, the only thing scenic is the fountain at the pond right at the entrance, or a few views within the herb garden.
