If you have a rental car from a Thai company, you can park on the Thai side of the border and walk across.

You can use Thai baht and US dollars at most vendors at the border market.

While visas are not required for citizens of most countries, you should check the regulations before attempting to cross.

The roads in Tachileik are of lower quality than those on the Thai side of the border, and people who use wheelchairs may find some difficulty getting around.
