Visit the Pitons by boat. My daughter caught a little boat booked from our hotel. The cruise included a lunch and visit to the sulpher springs. Apparently very good value for money, cannot remember cost now though. Best way to get those photographs is from a boat.
The Sulphur Springs and Drive Through Volcano.
Where else in the world will you be able to drive through a volcano? Now dormant,it is the world's only drive-in volcano and a tour of its bubbly, steamy sulphur springs offers a direct and fascinating lesson in the violent geology of the Caribbean Rim. A road leads into the remnant of a volcanic crater, where pools of muddy water bubble and shoot forth steam clouds 50 feet high.
This is one of the few historical sites on the island. Take the self guided tour and go all the way to the top of the hill. The ruins throughout are neat and the view at the top is incredible. Take plenty of film and some water. Jambe de Bois restaurant down on the beach is pretty good for lunch. The 'interpretive center' wasn't too impressive, but you can still get some good info there about the history of the island.
This park juts out from the island above Rodney Bay (the new Hyatt is right next to it). There's an old Fort, a pleasant and interesting restaurant, small beaches with few people, and hiking trails. Great view from the top of the fort!
Castries is Saint Lucia's bustling capital and its largest city, with a population of 65,000, It is home to the historic Cathedral of the Immaculate Conception; the scenic and historic hill of Morne Fortune; and a number of shops and other historic sites. The majority of the island's resorts are nearby.
Ah, there's so much to do including the Friday night 'jump up' (street party) in Gros Islet, the drive in vulcano, the beautiful tropical botanical gardens with the 'walk up' waterfalls, nightlife in Rodney Bay and the rain forest tour! Oh, and I almost forgot, the St. Lucia Golf and Country Club (I don't golf, yet)
You can't do it all in one trip!
Tour a historical point, there are so many that can be provided at the hotel or any tour company. Choose from the Morne Coubaril Estate, Mabouya Valley, Forestiere, Des Cartiers or La Tille Falls.
To go back in time to the days of the occupation by the British, French, Caribs and/or Africans.
Visit the little town of Soufriere- the oldest on the island. It was founded in 1746 and under French rule was the capital. This is not a tourist-trap town at all, but exists primarily for the islanders. There are ladies selling fresh fruits & vegetables on the street and fishermen selling their catch.
Some pretty colonial architecture
The best place we visited has got to be the banana plantation! Tour groups do organised tours to them but be warned getting there might be a bit steep!
It is a good place to visit because you can't just visit one everday. People who go shopping on holiday can go shopping any day but this is more like a once in a lifetime experience!
Visit the capital, Casteries and the Duty Free Areas. We had a taxi from our hotel.
It was nice to see the St Lucia and pick up some bargains in the Duty Free Shop and at the little colourful market.
Very steep climbing with a rastafarian guide. It is very hard and scary and don't do it unless you're fit. I was the only other woman that most people had heard of that had climbed it. The view was unbelievable at the top. Worth the effort!
Go snorkelling!! Also, go to Pigeon Island national park and climb up Signal Point - great views of Rodney Bay. Also, just get a car and cruise round. Soufreire and the south has the best beaches and scenery. The North is too touristy but has some good beaches too. Go to the waterfalls near the Pitons and the one in Anse La Raye - one is warm and one is cold!
Soufriere. The original capital under French rule, the fishing town is sleepy and laid back, but has loads of charm.
Check out the gingerbread houses before they collapse--and they look like they might any second.
Don't leave the island without getting a view of the Pitons from sea. They are the impressive peaks that are St. Lucia's trademarks.
There are two peaks--Gros Piton and Petit Piton. Petit Piton is the smaller, yet taller peak and I believe that you can no longer climb it after an accident occurred a few years back. Gros Piton still has a trail, but get a guide. I didn't have time to hike the trail, but will definitely do it the next time--apparently, you get a gorgeous view of the isalnd as well as a view of neighboring Martinique on a clear day.
Rodney Bay Marina. Filled with sailboats and yachts sailing flags from all over the globe, the marina is one of the most picturesque you'll find in the Caribbean. Sit by the piers and have a Piton beer or better yet, take a trip on a sailboat. There are charters for the day or for several days -- with or without crew.
