Mancora, chill, surf and party
Mancora is one of the first interesting cities for travelers and backpackers entering Peru from Ecuador.
There is a laid back atmosphere and great surf! One of the things you' ll definitely like compared to Ecuador is the food ! Cheaper and better, that’s a double win!
If you go to Mancora, make sure to book your stay at the Loki hostel. This is one of the best hostels i have been too as for location and outdoor accommodation.
swimming with turtles
While you are there, make sure to go diving with the turtles ! 40 minutes south from Mancora there is a harbor where turtles come to rest in a quiet bay. They say there are over 100 of turtles swimming there. As soon as you go in the water (you need to pay a small fee to enter from the pier) they'll start feeding the turtles. You will literally swim amongst dozens of turtles! Pretty cool!
Many tour operators will have daily trips, but you could easily do it yourself! Just hire a tuk tuk, make sure to ask a few and bargain for a better price and then go down there.
