What to expect
Day 1: fly from Lima to Tumbes and stay there. Day 2: visit the mangroves from the agreed departure point, then sleep around Tumbes again. Day 3: travel by road to your Máncora accommodation and leave the afternoon open. Day 4: a beach walk or a surf lesson suited to conditions. Day 5: another day without changing hotels, perhaps with one outing to a neighbouring beach.
How it fits into a journey
This short route can follow a longer Peru journey. With only three days, choose one beach base or Tumbes with the mangroves instead of rushing the same plan.
