Well, you have a few options.
Yes, you can in fact walk. Lima is not a walking city. It's a place where the car is king and therefore its not always the most pedestrian friendly. They give right of way to highways meaning you can lose a sidewalk here and there. But fear not, because Lima has poor people and poor people walk. So when the sidewalk ends, just look for a goat path and there will be people who have blazed their own trail. Oh, and get used to the smell of exhaust. It's like the natural scent of the city.
Honestly, I would pass on these. I'm sure they transport thousands of Limenos safely to their destinations every day, but as someone who's Spanish isn't great, its a lot of pressure. These things are wild.
As mentioned earlier, this is the brandy-new Bus Rapid Transit (BRT) line in Lima. And it's really popular and is able to bypass lots of traffic. Which is good, because Lima has a lot of traffic. You pay the fare at the above ground station and then walk down to the platform which is located in the median of the highway. Some tips:
- Have cash. Preferably small bills. No one like the guy in front of him at the Dunkin Donuts that pays with a $100. These people don't either.
- The card costs 4.5 soles, so if you buy one with a 5 sole note, that means you only have .5 soles credit. One of our guides lied and said that the card was 5 soles and came with 2 one-way rides. Mentiroso!
- The ride is 1.5 soles each way. So budget accordingly.
Peru is still viewed as a dangerous place, so Western hotels will take advantage of this and offer you the services of their taxis which can be nice Camrys or Audis. These vehicles do not have turbo boost though and have to sit in the same traffic as the yellow deathbox shown above. The hotels want 50 soles to take you to places that regular cabs will charge 8 soles for. So here's the deal, never take the hotel cabs, unless you're a single female or wear suits of money. The way I look at it, even if you get ripped off by your cab driver at 25 soles for the trip, you're still coming out ahead of the hotel gouging.
Oh, and you should look for these cabs as they're widely agreed by Limenos to be the most safe and reliable company.
There's a subway in Lima, but it doesn't go anywhere that useful, and its not underground. There is a second line being built underground, but the folks down there are skeptical what with the earthquakes and all. So I'm not including it here because I didn't take it and it seems like I wasn't missing much.
