The old Russian Ladas that plied the city streets in the 1980s and ’90s are fast giving way to newer Japanese and Korean imports. Taxis are a great way to get around and are well worth the extra money if you want to save time; in Managua [1], they’re essential for security reasons.
In every city except Managua, urban taxis operate on a fixed zone rate, usually under $1 within the central city area. In the capital, however, it’s a different story, and you are expected to bargain out a rate before sitting down. In all cases, avoid taxis where the driver is traveling with a friend, and pay attention to where you’re going.
