  • Central America ↗Guatemala, El Salvador, Honduras and Nicaragua (CA-4) give one shared entry allowance, usually 90 days in total; leaving for Belize, Costa Rica or Mexico and coming back does not always reset it — check with immigration before a long stay.
  • Central America ↗Cross land borders in daylight and early in the day; many posts close or empty of transport by late afternoon, and the approaches are where robberies happen.
  • Central America ↗Several borders charge entry, exit or municipal fees in US dollars (Belize exit, Nicaragua entry and exit, Honduras entry); carry small, clean US notes and ask for a receipt.
  • Panama ↗Check entry rules for your passport with Panama's National Migration Service or a Panamanian consulate; proof of onward travel and funds may be asked for.
  • Panama ↗Do not travel independently in the Darién; the UK and other governments warn against parts of it, and there is no road crossing to Colombia.
  • Panama ↗Guna Yala (San Blas) is governed by the Guna people: visitor fees apply, and photography of people usually needs permission and payment. Book through Guna-run or licensed operators.
  • Central Panama ↗Parts of the Canal watershed and the former Canal Zone are restricted or military land; stay on marked roads and trails.
  • Central Panama ↗US dollars work everywhere; small vendors and rural buses want cash, and cards fail outside the city.

  • Guided trail includes uneven ground and occasional mud; not suitable for limited mobility.
