Where to See Sea Turtles on the Big Island

Hawaiian green sea turtles—called honu in Hawaiian—are one of the most beloved animals in the islands. Once endangered, their population has rebounded thanks to decades of protection. Today, encounters with these gentle giants are a highlight of any Big Island visit.

Understanding Honu

Before seeking out turtles, it's worth knowing a bit about them:

• Size: Adults weigh 200-500 pounds and can reach 4 feet long
• Lifespan: 60-80 years in the wild
• Diet: Primarily seaweed and algae (the "green" refers to their fat, not shell)
• Behavior: They bask on beaches to warm up and rest
• Status: Protected under federal and state law
• Cultural significance: Honu are considered 'aumakua (family guardians) in Hawaiian culture

Best Beach Viewing Spots

Richardson Beach Park (Hilo)

Just 10 minutes from Island Goodes, Richardson's is one of the most reliable spots for turtle sightings. Turtles feed on the algae growing on the rocky shoreline and often rest on the small beach.

• Best time: Morning and late afternoon
• Facilities: Restrooms, showers, lifeguard
• Bonus: Great snorkeling when conditions are calm

Punalu'u Black Sand Beach

Famous for both its jet-black sand and its resident turtle population. Turtles rest on the beach throughout the day, often just feet from visitors.

• Location: South side of the island, near Na'alehu
• Note: Swimming is not recommended due to currents
• Ropes mark off resting areas—please respect the boundaries

Kaloko-Honokohau National Historical Park

This lesser-known park near Kona has a turtle cleaning station where fish clean algae off turtle shells. The sandy beach also attracts basking turtles.

• Free entry but limited facilities
• Short walk from parking to beach
• Also great for Hawaiian history and fishponds

Snorkeling with Turtles

For an underwater encounter, these spots offer excellent chances:

Two Step (Honaunau Bay)

Clear waters and abundant marine life make this a favorite. Turtles are commonly seen cruising along the reef.

Kealakekua Bay

The Captain Cook Monument area has resident turtles among its pristine coral. Access by kayak, boat tour, or long hike.

Richardson Beach

When calm, the protected cove offers easy snorkeling with frequent turtle sightings among the lava rocks.

Carlsmith Beach Park

A calm, sheltered area in Hilo with turtles often seen in the calm waters. Great for less experienced snorkelers.

Turtle Viewing Etiquette

Please help protect these special animals:

• Keep your distance: Stay at least 10 feet away (20 feet recommended)
• Never touch: It's illegal and can harm the turtle
• Don't chase: Let turtles approach you
• Stay quiet: Loud noises can disturb them
• Never feed: Human food is harmful
• No flash photography: Can disorient them
• If basking: Don't stand between turtle and ocean

Legal Protection

Hawaiian sea turtles are protected by both federal (Endangered Species Act) and state law. Harassment—including approaching too closely, touching, or feeding—can result in fines up to $100,000.

Best Time for Sightings

• Year-round: Turtles are present all year
• Morning: Best for beach basking (they warm up early)
• Midday: Often seen swimming and feeding
• Calm days: Better underwater visibility

Other Marine Life

While looking for turtles, you might also spot:

• Spinner dolphins (especially early morning)
• Colorful reef fish
• Moray eels (in rocky areas)
• Octopus (if you're lucky!)
• Humpback whales (December-April)
