Beware of unsolicited approaches from people purporting to be from hotels, travel agents, surf & salsa teachers & invitations to parties. Surprisingly attractive young people have learned phrases in numerous languages to convince you they coincidentally have a similar profession, interest in your language or country; or their family & friends in your country. They may 'happen' to bump into you several times during your stay. The more backpacks, daypacks, cameras, moneybelts, sunglasses & jewellery you display, the more you look like a Christmas tree. Recently they have been finding excuses to change false Peruvian and US dollar bills. (http://www.bbc.co.uk/news...)
Be careful at ATMs & on leaving banks, displaying cash in shops etc. Do not carry around belongings any more than is necessary & try not to put them down unobserved/unattended during transfers, in restaurants, internet cafes, buses etc.
Official taxis have post card sized municipal stickers with the city's coat of arms on it. They may have a surprising array of lies & other tactics to take you to more distant, expensive, isolated hotels & destinations to monopolize your future. The taxis from the airport, port & more expensive bus companies are the most ambitious.
Although they have one of the largest taxi fleets in Trujillo, be wary of "Americas" taxis. They have an awful reputation with regards to crime.
Beware of touts offering tours or hotels, it is much cheaper and convenient to book tours and hotels yourself, to avoid paying their commission.
Beware of fake reviews, with undue praise or criticism by such touts.
