Just your passport and a visa on arrival to enter the other country unless going to Malaysia or Myanmar (500 baht for a border pass).

Remember you are only allowed 2 visa exempt entries per calendar year at land border crossings.

You can extend the 30 day entry for 30 days at a immigration office for a fee of 1900 baht.
