Although U.S. dollars are accepted everywhere, you can exchange money at the border crossing near Benque Viejo. Money changers at the border often give slightly better rates. Banks in San Ignacio include Atlantic Bank, Belize Bank, and ScotiaBank. They are all downtown on Burns Avenue. Belmopan has branches of all five of Belize’s retail banks—Atlantic Bank, Belize Bank, First Caribbean International Bank, Heritage Bank, and ScotiaBank. ScotiaBank also has an office in Spanish Lookout. All these bank offices have ATMs, and all but Heritage Bank accept ATM cards issued outside Belize.
Here is a range of rates you can expect to pay for selected trips. These charges are per person and usually include transportation, lunch (on full-day trips), and, in the case of river trips, drop-off and pickup. Admission to Mayan sites (usually BZ$10–BZ$20, except about US$20 at Tikal), border fees (BZ$37.50 to go from Belize to Guatemala), may or may not be included—you should ask. Gratuities for guides are almost always extra. On some day trips, such as to Tikal or Caracol, there's often a flat fee for one to three or four persons, so the more going together, the cheaper. Keep in mind that, especially off-season, rates for some of these tours may be negotiable.
