Huaquillas is on the border of Ecuador and Peru near the coast. It's separated by a dirty river from its Peruvian counterpart Aguas Verdes. It's dirty, noisy and busy. Most travellers only come here because they have to.
Crossing from Ecuador to Peru used to be complicated and dangerous, and there were many scams. You will see horror stories on the Internet from years ago. Now, Ecuadorian and Peruvian border officials sit side by side in the same building.
From Huaquillas you can take a yellow taxi to the joint Ecuador-Peru migration office 15 min along the highway for $5 (Feb 2018). Your driver may tell you that the Peruvian taxis only take Peruvian soles and offer to exchange money at rip-off rates. Don't fall for it.
Line up first for to get into the building, and to be directed to a "Salida del Ecuador" desk. Then you have to queue a second time (inside the building) for an "Ingreso Al Peru" desk.
On your way out, look for the green-and-yellow sign that show the fixed-rate taxi fares to a dozen different destinations within Peru, e.g. US$10 or S/33 for the 20-30 min trip to Tumbes (Feb 2018). The drivers take either currency.
The emigration procedure is usually quick. On entrance to Ecuador you get a stamp in your passport. Onward tickets are seldom required and if so usually you can talk your way out of it.
In Huaquillas you have to cross the international bridge by foot. Either to catch a mototaxi on the Peruvian side to the emigration office or a taxi or bus on the Ecuadorian side to the emigration office.
Several bus companies have international lines between Guayaquil and Tumbes or further south. They wait at the immigration office. This saves a lot of hassle and is, in general, a cheaper way of crossing the border.
The town is quite small so you can walk most places. There are three-wheeled "tri-moto" cabs. However, like any place, you might want to stay off streets that are darker or where there is little foot traffic.
The little plaza in the middle of town is small but nice.
There is some shopping on the main street towards the Peruvian border, but not much. Agues Verdes on the Peruvian side has more. For more shopping, try Machala about an hour north.
This border crossing is known for muggings and robberies, be very careful of your personal belongings and safety.
