Anguilla and its Visitor Cays

December to April is the most straightforward period for planning Anguilla scuba because the island is in its generally drier high season and outside the official Atlantic hurricane season. That does not mean seas are always flat or visibility always high. Scuba Shack selects reef or wreck sites according to the actual sea state and diver experience. May and June can still be useful with flexible dates. During June-November, and especially the higher-risk period from mid-August to mid-October, allow for cancelled boats and interrupted connections. No verified monthly visibility measurements justify a more precise dive-only peak.

Do not plan a self-guided shore scuba holiday here. Anguilla's Department of Fisheries and Marine Resources says scuba in its marine parks must be accompanied by a local dive operator; PADI's Scuba Shack listing explicitly notes that shore scuba is not permitted by local regulations. The government regulations also refer to operator supervision or a separately issued permit, so the exact legal distinction should be checked with Fisheries rather than assumed to authorize a visitor shore entry. A beach that is suitable for surface snorkeling is not necessarily legal or appropriate for scuba. Book a locally guided boat programme.

The practical restaurant and beach stops are Sandy Island from Sandy Ground, Prickly Pear East with an arranged boat and Scilly Cay from Island Harbour. Sandy Island's direct operator advertises daily shuttles November-August and group reservations only in September and October. Scilly Cay's direct FAQ limits normal public visits to particular weekdays, despite broader header hours, so call first. Prickly Pear has a restaurant and watersports but no generic permission to land anywhere on either cay. Dog Island and Sombrero are protected wildlife locations, not casual independent beach-hop stops. Always check sea state and return transportation.

Little Bay is a strong verified guided snorkeling option. Scuba Shack advertises guided snorkel trips in the cliff-backed marine park, and the Anguilla Tourist Board identifies Little Bay as a notable coastal stop. It is part of the main island, not an offshore cay. A short local boat is easier to plan than assuming a safe cliff or rope access route. Its deeper edges and possible boat activity mean the guide should choose entries based on swimming ability, current and wind. For mixed groups, request a proper snorkeling guide and flotation for anyone who needs it.

Some operators offer shallower reef and wreck experiences for Open Water divers, but the wreck label alone says nothing about suitability. Scuba Shack publishes different one-tank and two-tank depth profiles and actively chooses the sites for the group. The government maps named wrecks such as MV Sarah and MV Oosterdiep, but their appearance on a map is not a confirmed departure. Ask the operator about the exact depth, current, bottom time, supervision and whether an external-only route is planned. Never assume wreck penetration, a historical artifact visit or technical overhead diving is included in a recreational booking.

A standalone freediving course was not verified for the research cutoff. PADI lists freediving among Scuba Shack's activities, but the operator's detailed course and service pages did not establish specific current dates, a named instructor, depth line or dedicated safety boat for breath-hold training. That is a lead to check with the dive center, not a bookable promise. Snorkeling at Little Bay or joining a scuba boat is not a substitute for qualified freedive supervision. If depth training is the main reason for travel, obtain written confirmation of the course and rescue plan before choosing flights or accommodation.

Many visitors fly to Princess Juliana International Airport (SXM) on the Dutch side and travel overland to French-side Marigot, where the public ferry goes to Blowing Point, Anguilla. Anguilla's government posts the route timetable and a separate one-way fare, plus departure charges depending on the route, age and whether the traveller has stayed more than 12 hours. You pass through immigration and customs and may need to meet entry rules for both Dutch or French territory and Anguilla. Allow generous flight and port connection buffers and verify same-day schedules. AXA airport also accepts connecting and selected direct services.

The government's published park guidance directs visitors to dive with a local dive operator and sets rules for marine moorings. It does not establish a separate, universal, individually purchased scuba visitor tag in the sources reviewed. Ask your operator whether all applicable local permissions and marine charges are included and whether you need to carry anything. The Department of Fisheries and Marine Resources publishes separate fees for visiting vessels and park moorings; those are not automatically payable by each passenger on a licensed dive boat. Fishing, anchoring outside designated areas and removing artifacts or wildlife are not permitted in the marine parks.

A non-diver can spend time on Shoal Bay East, Meads Bay or West End beaches, visit Island Harbour or join a separately arranged Sandy Island, Scilly Cay or Prickly Pear East lunch day. Anguilla National Trust has published West End-to-Barnes Bay and Windward Point walks, but dates and guiding should be reconfirmed. Scuba Shack also markets private combined dive-and-snorkel charters with passenger places, which may suit a family that wants to remain together. Check that the exact stop offers an appropriate swimming area; no one needs to enter the water simply because they share the dive boat.

Call 911 for an emergency in Anguilla. Princess Alexandra Hospital is the named local hospital, and UK government advice also lists a maritime-emergency telephone number. The government's Dive Tourism Policy reported no local hyperbaric access when written. A September 2026 parliamentary statement reported new chamber investment, but did not confirm operational emergency treatment. Before any dive, verify the operator's emergency oxygen, extraction, communications and chamber-transfer arrangements, plus your insurer's decompression-treatment and evacuation cover. Severe illness or injury may require transfer off island. Keep a conservative post-dive flight interval.

Anguilla generally fits a premium rather than budget travel plan, particularly when adding chartered boats or resort accommodation. Scuba Shack advertises a scheduled two-tank certified dive with tanks and weights at US$220 and with rented equipment at US$250; Quest has lower but different listed packages whose inclusions need confirmation. A private mixed-group boat is substantially more costly than joining a scheduled trip. Ferry fares, departure taxes, taxi or car rental, meals and island-cay shuttles are additional. US dollars are widely accepted but XCD is the official currency. All listed prices are snapshots, not guaranteed final quotes.

Sea turtles are an evidenced wildlife goal: Scuba Shack describes potential turtle observations on its guided Little Bay reef outings, and official UK conservation material identifies Anguilla as important for turtle foraging and nesting. No operator can guarantee encounters, and the presence of wildlife does not prove a site is safe. The Anguilla National Trust historically listed September-October turtle patrols, but its page is old and current tour dates were not confirmed. Dog Island, Prickly Pear and other remote cays are important seabird habitats; do not land, approach nesting colonies or operate drones without current authorization.
