Trunk Bay

Overview

Trunk Bay is the island’s postcard beach: powdery white sand, luminous turquoise water, and a long crescent framed by palm-studded headlands. It’s the most developed beach in the park, which means you get the best mix of natural beauty and convenience.

Why it’s special

Beyond the scenery, Trunk Bay is home to a self-guided underwater snorkeling trail that loops around tiny Trunk Cay. It’s beginner-friendly, and the interpretive plaques make it feel like a living aquarium tour rather than just another reef swim.

Snorkeling: what to expect

• Underwater Trail: About 650 feet long with buoy markers and plaques that identify reef life and explain coral etiquette.
• Marine life: Expect colorful reef fish and frequent stingray sightings; lucky snorkelers report sea turtles and even squid. Some sections of coral show stress—go easy with your fins and never stand on the reef.
• Conditions: The bay is usually calm and easy, but start on the west side of Trunk Cay, keep to your comfort level, and skip it if surf kicks up.

Amenities & logistics

• Facilities: Flush restrooms, showers, potable water/bottle-fill, picnic tables/pavilion, and first aid.
• Food & rentals: A daytime snack bar/beach bar serves quick meals and drinks; you can rent snorkel gear, life vests, chairs, and umbrellas.
• Fees: Trunk Bay is the only beach here with an admission fee (about $5 per adult; youth 15 and under free). Most national park passes are accepted.
• Getting there: Roughly 10 minutes by taxi or rental car from Cruz Bay; parking is limited, so earlier is better.
• Rules: Kayaking and paddleboarding are generally not allowed within the swimming areas here. Lifeguard coverage can vary—plan to be self-reliant.

Best time to visit

• Timing: Arrive early (before 9 a.m.) to snag parking and quiet sand, or come late afternoon for softer light.
• Crowds: Expect peak crowds late morning to mid-afternoon, especially on cruise-ship days.
• Photography: Stop at the roadside overlook along the North Shore drive for a classic elevated shot before dropping down to the beach.

A quick geology note

The coves and headlands that shelter Trunk Bay are carved into ancient volcanic bedrock, which helps create the calm, scalloped shoreline that makes this bay so inviting.

Wildlife & care for the reef

The bay’s name nods to the leatherback sea turtle (called “trunks”). Watch for rays gliding over the sand and schools of reef fish near the cay. Use reef-safe sunscreen, keep your fins off the bottom, and give all wildlife respectful space.
