I don't use route taxis often but when I do I pay $200 JMD from one beach area to another or from beach to downtown. From the end of beach down by Travellers or downtown to the west end I pay $200 JMD. From one beach location to another with a private taxi I usually pay $700 JMD or $5 USD. From beach area of boutique hotels with a private taxi to the west end I usually pay $1,400 JMD or $10 US. For a private taxi from beach area of all inclusive resorts to the west end I'd expect to pay $2,000 JMD-2500 JMD or $15-20 USD. Everything is always negotiable in Jamaica and I'm sure there are some who can get it for less but I consider that fair. Some will want more but most will take those prices. I've found if you try to use the same private taxi for most of your stay then the prices will go down and some will just negotiate a flat rate for the entire week to bounce around Negril.
