How it works:
- Before the entrance, there are locals who may block your path and demand you pay the entry fee to them for tickets.
- The place is either free to enter, or no tickets will be given to you.
Places to beware:
- Cusco: Cerro Colorado Vinicunca, San Blas
What to do:
- Check for yourself if a place is free to enter and only buy tickets direct from company/official counters or licensed retailers.
