At Oasis Sea World at Laem Sing near Chantaburi you can watch dolphins, penguins and sea lion shows, and also, by pre-booking in advance, have a chance to swim with the dolphins.
Apart from the obvious attractions of the park, the on-site restaurant can cook up some delicious Thai food at very affordable prices, so taking a day trip to this attraction is well worth the visit, especially if you get to swim with the dolphins.
Nearby the park is Laem Sing Beach, which also has a number of inexpensive seafood restaurants, and you can also get a boat trip out to the nearby island and around the picturesque coastline. If you have time you may also wish to take a look at the gem market in Chantaburi town whilst you are in the vicinity.

(Note that in Earth mode you will need the Google Earth plugin for your browser, but it’s quick to install and will allow you to zoom much more quickly and display popup information much better too)
