What is the easiest land border run from Bangkok to neighboring countries?

For easy land border runs from Bangkok, travelers often recommend Cambodia, specifically avoiding the Poipet border due to its complications. Agencies frequently offer trips for a quick border run to Cambodia, allowing for a same-day trip. Alternatively, the sleeper train to Malaysia is noted as a hassle-free option, especially for EU passport holders. Another option is the night train to Vientiane, Laos, which recently opened its borders with a 15-day visa-free stay for certain European nationalities. Travelers should also be cautious about entry limits into countries for visa-exempt travelers.
