Roatan is the biggest of the three main islands (the others being smaller Utila and tiny Guanaja) and is the most developed of the three, both in terms of tourist facilities and general infrastructure. The islands' economy is apparently based mostly on fishing, but tourism—mainly in the form of its terrific snorkeling and diving—must be coming up fast.
It’s not particularly cheap and you can expect to pay twice or three times the costs you’ll find on the mainland (even in touristy areas such as Copan). The one thing that is a bargain though is SCUBA–much cheaper than neighbouring Belize–about per one-tank dive, or even less for a block-booking of 10, or about for a PADI open-water course.
There’s more to Roatan than the coast though, and the Carambola gardens merit a special mention to get away from the sun and sand and climb up amongst birdlife and the local crested iguanas to be rewarded by a magnificent view.
Most visitors to Roatan will stay in West Bay or West End, where there’s a good choice of hotels and restaurants and life revolves around trips out onto the crystal waters. Compared to other areas of Honduras, the island feels very safe indeed, and you wouldn’t think twice about wandering around after dark.
Note also that, whereas US are only sometimes taken on the mainland, you can virtually exist without Lempira on the islands because of the prevalence of foreign visitors and American expats.
Quick Tips:
Top spots to stay and dive/snorkel/swim/just laze around are West End/Bay; visit Carambola Botanical Gardens to stretch your legs by hauling yourself up Monte Carambola (the highest part of the island, giving a fantastic view as well as being a lovely climb).
In West End itself, a new boulangerie has opened that is run by "the Frenchman" on the main street before the road to Sandy Bay. It has free Internet connection (as do many of the hotels and dive-schools once you commit to them) and the most fantastic views while you eat authentic baguettes: try the chicken or BLT (50L) and the island's best, cheapest mugs of good coffee (10L). Don’t buy small bottles of water for a high price—the best supermarket is southwards past the Sandy bay turnoff (not as far as Twisted Toucan) which sells 5-litre casks to decant (decent hotels provide a ‘fridge). Alcohol isn’t cheap–there are some happy hours but most supermarkets sell bottled rum for about , if you’re happy to sit on your veranda (you’ll get bitten by tiny, unavoidable sandflies either way–don’t believe what people tell you about baby oil stopping them).
Best Way To Get Around:
There are taxis from the airport via Coxen Hole (the dusty, uninspiring capital) to West Bay/West End for about 190 to 200Lempira (). There's also a bus from outside the airport compound, or from the dock if you take the twice-daily boat from Ceiba.
As for getting around, I wouldn't say it's necessary to hire a car unless you plan to travel north beyond Oak Ridge (i.e. towards the dirt track to Port Royal) as the road all but peters out and is not recommended on a moped! Otherwise, you'll only need a moped to nip around for a day, if you can drag yourself from the sand. Expect to pay about for a 24-hour hire (plus to fill-up with petrol) from a small place in West End, though it pays to shop around as prices do seem to vary. Best reason to hire a moped is to see the small towns and "countryside," and the views down to the coast on each side as you drive along the one good road (while it lasts!) along the backbone of the island.
