Snorkeling Guide to Coki Beach, St. Thomas


I. Why Coki Beach for Families

Coki Beach offers easy shore snorkeling in St. Thomas with abundant reef fish visible within 10 feet of the sand, even in shallow water, making it accessible for young children. Its proximity to Coral World Ocean Park also means a lively environment with marine activity. The main drawback for families is that the beach often becomes very crowded, particularly on cruise ship days, and you will encounter numerous vendors (touts) upon arrival. For more options on best snorkeling in St. Thomas for families, consider other spots.

II. The Approach and Parking

Parking at Coki Beach, a popular St. Thomas beach, is in a small, unpaved lot directly adjacent to the beach at Coki Point. This lot typically fills by 9:30 AM on cruise ship days and weekends. On weekdays without cruise ships, spaces may be available until 10:30 AM. Expect congestion when both arriving and exiting the parking area due to limited capacity and beach traffic. The walk from the main parking area to the sand is a flat, paved path measuring approximately 50 yards. It is a direct route with no significant inclines or uneven terrain.

III. Getting Kids Into the Water

The main entry point for Coki Beach is a wide, sandy area directly from the parking path onto the sand. For the best snorkeling at Sapphire Beach or Coki Beach, walk to the right side of the beach (facing the water) until you reach the rocky outcrop that separates Coki Beach from Coral World. The water here is typically calm within the cove, showing minimal surge. Depths are waist-deep for an adult for the first 10-15 yards. Visibility usually ranges from 20 to 50 feet in favorable conditions, especially during morning hours. Afternoon conditions can see a slight decrease in visibility due to increased human activity and occasional localized chop from passing boats.

Safety Note: The area near the rocks on the right side contains shallow coral patches. Instruct children to avoid standing on or touching the coral to prevent cuts and protect the reef ecosystem.


IV. Spotting Marine Life

To locate marine life, enter the water on the right side of the beach, near the rocky boundary separating Coki Beach from Coral World. Swim approximately 10-15 yards out, paralleling the rocks. The main reef structure and fish activity begin at a depth of 3-5 feet. You will frequently observe schools of Blue Tangs, various Parrotfish (e.g., Stoplight, Queen), Sergeant Major fish, yellowtail snappers, and occasionally small grunt. Look for French and Gray Angelfish closer to the larger rock formations. Small eels are sometimes visible tucked into crevices along the rocks at depths of 5-8 feet. While turtles are present in the broader East End reefs of St. Thomas, they are less commonly sighted within the main Coki Beach snorkeling area. For another great snorkeling spot, consider Brewers Bay.

In-Water Parent Tip: The fish at Coki Beach are accustomed to human presence and often gather around snorkelers, especially near the rock areas. Advise children to swim slowly and hold still for a few seconds to observe fish without startling them.


V. Beach Facilities and Shade

Restrooms are available behind the row of vendors and shops, approximately 20 yards from the sand. These are basic beach facilities and are generally functional. Outdoor freshwater rinse showers (cold water only) are located near the restrooms. Natural shade on the beach is limited to a few scattered palm trees. These provide shade until approximately 10:30 AM on the left (west) side of the beach and until 11:00 AM on the right (east) side. After these times, the beach is mostly in full sun. Consider bringing your own shade tent or umbrella if staying for longer periods.

Pro Tip: Bring small denominations of cash for parking attendants or various beach vendors. Local food stands are readily available directly on the beach, providing quick lunch options such as burgers or regional dishes.


VI. Essential Gear for Coki Beach

  • Reef-safe sunscreen: Protects both your family’s skin and the coral in the approachable reef areas.
  • Water shoes: The sandy entry transitions to areas near the rocks and reef with sharp coral fragments and potential sea urchins.
  • Rash guard: Provides crucial sun protection for extended time in the open sun, as natural shade is limited.
  • Small dry bag: Keeps your phone, keys, and wallet protected from sand and water spray on a potentially crowded beach.
  • Swim buoy or bright vest for young children: Increased boat traffic and general beach crowds can make it harder to spot children in the water or from the shore. You might also want to look into best kids’ snorkels for this location.
