Never been to Tortola
Here is a little blurb about
Tortola and most of the British Virgin Islands are mountainous, and while they boast verdant-green hills, the climate and vegetation are much drier than many Caribbean isles. In Tortola, cactus and succulents are more common than ferns, and rushing streams and waterfalls are virtually nonexistent. The dry climate of the islands has a beneficial side effect: because of the lack of runoff, the water clarity is dependably higher than many other places in the Caribbean.
For that reason, Tortola and the BVI are a popular destination for divers and snorkelers. The protective effect of the islands surrounding Tortola causes the seas to be calm most of the time, making the region an attractive destination for those prone to motion sickness during small-boat excursions. The steady winds and calm seas also make Tortola and the BVI one of the world's premier yachting regions. Sailing excursions should be at the top of every interested visitor's list.
A visit to Tortola also offers a chance to experience other islands in the BVI chain. These include Norman Island, Jost Van Dyke, Peter Island, Marina Cay and Virgin Gorda. All are within reach for a day trip from Tortola, assuming you have a full day in port. This is not the case on all itineraries, so be sure to check ferry and ship schedules carefully before departing.
One of Tortola's greatest attributes is the genuinely friendly attitude of its residents. The island is safe and crime-free. It's not unusual to find yachts worth hundreds of thousands of dollars docked in marinas with keys visible in the ignitions.
