Off the sun-slicked coast of West Maui, the Carthaginian wreck sits as an unexpected underwater classroom for certified divers. This Wreck Dive departs from Lahaina Harbor, Maui, and in a ten-minute run you arrive at a 100-foot steel hull resting at about 95 feet where coral and life have turned metal into reef habitat. The trip is focused and small: maximum ten divers and a 5:1 guide-to-diver ratio let guides point out rare deep-water tropical fish and other species that seldom appear on near-shore reefs.
Your first descent is a structured exploration of the Carthaginian. The operator treats the wreck as diver safe — there is no penetration, no tight swim-throughs, and clear lines of exit — so the experience suits certified divers seeking wreck-associated life without the complexity of penetration training. Visibility can open onto schools of tight-bodied snappers and lionfish, while brittle stars and encrusting sponges lace the hull. Because the structure sits deep, many species seen here are uncommon on shallow reef dives.
After a surface interval aboard the boat you drop into a shallow reef for the second dive. Green sea turtles graze on algal patches, reef fish in saturated colors patrol bommies, and on occasion a reef shark cruises through the blue. Photographers and naturalists alike will appreciate the contrast between the deep, wreck-associated community and the sunlit reef life.
Logistics are straightforward. Check in at Lahaina Harbor, bring your scuba certification card (Open Water or higher) and arrive at least 15 minutes before departure. The trip runs roughly 4.5 hours and operates about three times per month, depending on sea conditions. Nitrox and larger tank upgrades are available for those who want longer bottom times or deeper profiles. Minimum age is 12; divers who haven’t been diving in two-plus years should book a refresher first.
Why book this over a typical reef drift? The Carthaginian creates access to deep-water species and an artificial-reef architecture that concentrates marine life. The short transit from Lahaina Harbor means more time underwater and less time underway. For visitors staying in Lahaina or nearby West Maui resorts, this guided small-group Wreck Dive pairs historical intrigue with lively marine encounters and delivers high value in a compact morning or afternoon on the water.
Trips typically cost $299 per person and include two tanks, making it a solid value compared with longer charters; upgrades for Nitrox (+$20) or an XL 100 cu ft tank (+$8) are options. Expect pre-dive briefings on surface intervals, equalization, and exit procedures; the crew emphasizes conservative dive profiles and bailout plans. Because the voyage is short, the boat spends more time on-site, and the small-group format helps reduce swimmer disturbance around resting turtles and fragile coral spots.

Extended Horizons Scuba is a Lahaina, Hawaii-based dive operator offering small-group scuba experiences and guided shore and boat dives around Maui and Lana‘i. The company specializes in low guide-to-diver ratios—typically four divers or fewer—so guests receive personalized attention from certified naturalists, marine biologists and experienced dive guides. Trips include shore dives from Lahaina, night dives, certified shore dives, a popular two-tank Lana‘i boat adventure that visits Cathedral dive sites such as First and Second Cathedral, and private and introductory scuba options for beginners. The Lana‘i two-tank excursion includes two dives at different locations, a warm lunch catered by Chef Marcos from Hungry Coyote, and access to over 40 possible dive sites ranging from coral reefs to lava tubes. Shore-based options highlight local reefs where divers commonly encounter green sea turtles, octopus, colorful nudibranchs, rays and diverse reef fish. Night dives focus on invertebrates such as lobsters, crabs, octopus and hunting eels, using bright LED lights and small groups for ideal visibility and attention. Introductory lessons require each participant’s name, height, weight and US men’s shoe size to ensure proper equipment fit. Refresher dives take place at Kahekili Reef to rebuild confidence and skills. Extended Horizons Scuba’s offering emphasizes conservation-minded guiding, slow-paced observation to maximize marine life sightings, and guided commentary that shares local marine ecology knowledge with divers of varied experience. Tours run year-round out of Lahaina waters.
