Although a bit further removed from attractions related to cult icon Bob Marley than other cities in Jamaica, there is still enough to do to satiate a passion for (or curiosity of) the island's culture. You won't find many ancient buildings or picturesque city squares here; if your intention was to see stuff like that, then you ought to get out from under your rock more often or, at the very least, listen to some reggae. The culture worth experiencing here is more of the last fifty years and more dependent on tourism than you'd probably like to believe.
Negril's center of affairs is on the water. There are a lot of resorts along the few miles of beach, as well as bars and restaurants that thrive on the patronage of both tourists and locals. As far as cultural highlights, you'll have to leave the city limits for much of significance. Just north is the Rhodes Plantation, a former 19th century sugar and rum distillery. Head about 100 km east to the Appleton Rum Estate for a tour of the grounds and a chance to sip on a brand that has been going since 1749. For reggae purists, there is a small Peter Tosh monument along the A2 toward Treasure Beach, but it really isn't much more than a mausoleum and a few related artifacts. For a sense of indigenous culture, your best bet is the Outameni Experience, which is a couple of hours away via route taxi. Located in Trelawny, performances are put on and artifacts arranged representative of Taino culture, a heritage claimed by some Caribbean peoples despite the fact that they were thought to have been destroyed by the Spanish.
Although there aren't a ton of cultural attractions in or near Negril (the Bob Marley-related activites are located in Kingston and Saint Ann, much closer to the east end of the island), we suspect you weren't coming for the culture anyway.
