Alaska's frigid waters are a hidden gem for divers and snorkelers seeking an adventure; with visibility exceeding 30 feet in places like Ketchikan and Sitka, you can explore underwater ecosystems teeming with life.
To dive or snorkel in Alaska, your journey often starts in Anchorage, the state's largest city. You can find direct flights from major cities like Seattle to Ted Stevens Anchorage International Airport, which typically costs around $300-$400 round trip. From Anchorage, you'll likely want to head to either Ketchikan or Sitka, where dive shops and charter services are readily available. Alaska Airlines operates daily flights to Ketchikan (approximately $150 one way) and Sitka (about $200 one way) from Anchorage.
Once in Ketchikan or Sitka, local transportation is quite accessible. In Ketchikan, the local bus service (costing $2 per ride) can take you to popular spots like Rainbird Lodge, a recommended dive center. Alternatively, if you're in Sitka, consider renting a kayak for an up-close water experience, with rental costs starting at $30 for a half-day. Regardless of your destination, you'll find local operators eager to help get you submerged in Alaska's scenic waters.
Start your underwater adventure in Ketchikan at the astounding, marine-rich waters of the Tongass National Forest. The area is known for its vibrant kelp forests and an array of marine life, including sea lions and octopuses. Dive operators like Ketchikan Dive Company offer packages starting at $175 for a guided dive, including gear rental. They typically depart from Thomas Basin Dock, where you can enjoy stunning views of the harbor before jumping into the depths.
In Sitka, head to the Sitka Sound Marine Park, recognized for its dive sites like the famous "The Pinnacles" and "The Kelp Forest." These spots provide mesmerizing views of colorful anemones, vibrant starfish, and schools of herring. Sitka Sound Tours offers snorkeling excursions for around $125, which include all necessary equipment and a guide to ensure you experience the best of the underwater world. Make sure to check local tide charts to choose the best times for visibility and marine activity.
Alaska's underwater ecosystem is astonishingly diverse. During your dives and snorkels, expect to encounter species such as halibut, salmon, and various types of rockfish. The waters are cooler, with temperatures averaging 45°F to 55°F (7°C to 13°C) even in the summer months (June-August), so wearing a 7mm wetsuit or drysuit is essential to stay warm. Dive shops often provide rental suits, but it’s wise to book in advance, especially in peak season.
Plan your diving or snorkeling trips around the lunar phases, as this can greatly affect marine life activity. New and full moons often bring more significant tidal movements, which can enhance visibility and increase the chances of encountering larger marine creatures. Always check with local dive shops for recommendations on the best times to go based on lunar cycles and local tides.

The best time for diving in Alaska is during the summer months, from June to September.

Additionally, marine life is abundant, with species like salmon and halibut more active during this time.
While snorkeling does not require certification, you should have a basic understanding of water safety. For diving, most operators require at least an Open Water Diver certification from agencies like PADI or SSI. If you’re not certified, consider taking a course with a local dive shop before your trip to ensure you have the skills to explore safely.
