Tide Pool Marine Life

The tide pools in Olympic National Park are a bustling ecosystem filled with diverse marine life. These creatures have evolved to thrive in the constantly changing environment of the tide pools, where they must endure the tides’ constant ebb and flow.

Sea stars, anemones, barnacles, and mussels are among the most common inhabitants of the tide pools. They can often be seen clinging to rocks or other surfaces, filtering out plankton and other organic matter as it drifts by in the water.

But there are also many other fascinating creatures that call Olympic National Park’s tide pools home. From hermit crabs to chitons to various species of fish, these animals have adapted to survive in the harsh conditions of the tide pools, facing challenges such as fluctuating temperature, salinity levels, and oxygen levels.

One of the most captivating aspects of exploring these tide pools is witnessing the remarkable adaptability of these marine organisms. As the tides ebb and flow, these creatures must quickly adjust to the changing conditions in order to survive.

Most Popular Tidepools

Some of the most visited tidepools in Olympic National Park are located at Kalaloch’s Beach 4 and Mora’s Hole in the Wall. Other popular spots include Second Beach, Third Beach, and Ruby Beach. For details on the best beaches in Olympic, see our guide.

The key to successful tidepooling is timing. Tides at the park change daily, and not all low tides provide the same viewing opportunities. The best time for tidepooling is during a “minus tide”, when the water levels are even lower than usual. Aim for tides that are less than 1 foot for optimal tidepool exploration.

Safety in the Tidepools:

  • Always keep an eye on the tide and be aware of “sneaker waves” that can quickly return.
  • Be cautious when walking on rocks covered in algae and seaweed, as they can be very slippery. Test each rock before putting your full weight on it.
  • Wear sturdy shoes that you don’t mind getting wet.
  • Keep a close watch on children, as rocks and waves can be unpredictable and lead to serious injuries if not careful.
  • Do not bring dogs onto the tidal rocks, as their paws can get cut by sharp stones, barnacles, and mussels which may cause infection.
  • Avoid jumping from one rock to another; always have at least one foot firmly on the ground.

Important Safety Precautions for Hole in the Wall:

Avoid crossing through Hole in the Wall when the tide starts to cover the floor of the arch. This area is constantly hit by waves, and rocks can fall at any time, making it dangerous to stay under or next to the arch for long periods of time. If you hear rocks falling, protect your head and move away from the arch.

If you plan on exploring the tidepools at Hole in the Wall alone, make sure to arrive at least 30 minutes before the lowest tide. Keep in mind that it takes a 1.5 mile (1 hour) hike from the parking area at Rialto Beach to reach Hole in the Wall.
