The Itinerary in Detail

The tour begins at 78-6831 Ali‘i Dr in Kailua-Kona, where check-in is straightforward. The boat, a zodiac-style RHIB with seating on a pontoon, departs for about 2.5 hours on the water, giving you plenty of time to enjoy each stop.

Stop 1: Kealakekua Bay and Captain Cook Monument

This is the highlight — the main reason most people sign up. The bay’s crystal-clear waters attract hundreds of tropical fish, and the reefs are a vibrant underwater city. A couple of things set this stop apart: the boat’s crew provides a lively narration about Captain Cook’s history here, which adds a layer of cultural context to your snorkel. The guides are known for sharing Hawaiian legends and history, enriching what could otherwise be just a pretty reef.

The snorkel time here typically runs 30-40 minutes, and many reviews mention the extraordinary variety of marine life. One guest said, “checking in was easy, the crew was great, and the snorkeling was amazing.” The reef is home to Hawaiian green sea turtles, or Honu, which are often seen gliding across the coral garden.

Scenic Coastline Exploration

Before or after the main snorkeling, the boat makes a sightseeing loop along the coast, where you can view sea caves and lava tubes carved into the Kona coast. These geological formations are impressive, providing a dramatic backdrop to your water adventure. Some reviews mention the scenic views as a highlight — the unobstructed vistas of the coastline are worth the trip alone.

Watching for Marine Life

Depending on the season, you might see dolphins or even humpback whales on your ride back to port. Several reviewers have shared stories of spotting dolphins swimming alongside the boat, and during migration season, whales are often observed breaching or spouting nearby. This spontaneous wildlife watching is an added bonus that makes each trip unique.

What’s Included and What Not

The price of $99 per person covers the boat ride, snorkeling gear, snacks, and beverages, which makes it quite a good deal for what’s packed into this 4-hour experience. You’ll get light snacks, fresh fruit, juices, and bottled water, giving you enough energy for your underwater adventure.

The guides also provide pool noodles, which help with floatation for less experienced swimmers. However, please note that restroom facilities are not available on the boat, so plan accordingly. Gratuities are appreciated but not included, and tipping your crew is a customary way to acknowledge their effort.

Practical Tips & Considerations

• Most travelers find the check-in process smooth, but wearing reef-safe sunscreen (preferably zinc-based, no oxybenzone or octinoxate) is essential to protect Hawaii’s coral.
• Bring a towel and cover-up for after snorkeling, as the boat is quite basic in amenities.
• The minimum age is 6 years old, and participants must be comfortable treading water or swimming unassisted.
• The maximum weight limit is 285 lbs, and physical fitness is considered when deciding to participate.
• Climbing a metal ladder back into the boat is required, so keep that in mind if you have neck or mobility issues.
• While most travelers enjoy the experience, the boat can be a little choppy, and amenities are simple.
