Wear comfortable clothing. It is recommended to have a sturdy pair of broken-in trail shoes, boots, or sneakers. It is preferable to dress in layers and wear clothing that will wick away perspiration and keep you dry and comfortable. Some tours specify certain requirements (such as socks on ATM and long pants on Black Hole Drop) – please review your tour information carefully and be sure to ask if you have any questions.
A day pack to carry towels, change of clothes, etc comes in handy. River tours are comfortable with water shoes and rash gaurds (but t-shirts and sneakers that you dont mind getting wet are just fine). Out on the cayes a large brimmed hat, sunshades, sunblock are vacation-savers. In the jungle, lightweight long pants, and long sleeve shirts over tank tops are comfortable. On some jungle tours, knee high or short pants are fine.
Currency: everyone in Belize accepts US$ dollars. Most major hotels, tour shops and stores accept credit card – but on-site and remote gift shops and vendors do not have credit card facilities – a little extra cash comes in handy.
