An enchanting ocean-side forest adventure featuring tidal sections, ancient fern groves, and abundant wildlife. This moderate loop offers stunning coastal views while teaching essential tide-timing skills.
This trail includes two sections that are impassable at high tide. Planning your hike around tide windows is essential for safety. The trail crosses tidal zones at miles 3.2 and 7.8.
Morning Window:
Start between 6:20 AM - 9:45 AM for safe passage
Evening Window:
Start between 7:05 PM - 9:30 PM for safe passage
Note: Tide times vary daily. Always check current tide charts before your trip. Consult our weather and timing planning guide for detailed instructions.
What happens if you're caught? If you miss the tide window, you'll need to wait 6-7 hours for the next low tide. There are no safe high-tide bypass routes. Always carry extra food and water in case of delays.
Begin at the Coastal Trailhead (sea level) early in the morning to catch the first tide window. The trail immediately enters a dense coastal forest dominated by Sitka spruce and western hemlock. The first 2.5 miles are relatively flat, following an old logging road that's been reclaimed by nature.
🌊 First Tidal Crossing (Mile 3.2):
This is your first critical timing point. The crossing is a rocky beach section approximately 200 yards long. At high tide, waves crash against the cliffs, making passage impossible. Check your watch and ensure you're here during the safe window.
After the first tidal crossing, the trail climbs gently through old-growth forest. You'll notice the understory becomes dominated by sword ferns, giving this trail its name. The ferns can be chest-high in places, creating a magical, primeval atmosphere.
Water is abundant along this section—multiple streams cross the trail. However, all water must be treated. We recommend our water treatment guide for selecting the right system for coastal conditions, where water may contain salt or organic matter.
Fern Grove Camp (mile 9.8, elevation 280 ft) is a beautiful campsite nestled in a grove of massive ferns. The site has space for 4-5 tents and includes a bear box for food storage (required—see regulations below). The camp is well-protected from coastal winds but can be damp due to the forest environment. Ensure your shelter handles moisture well.
Day 2 begins with a gentle descent back toward the coast. The trail alternates between forest sections and open coastal bluffs offering spectacular ocean views. This is prime wildlife viewing territory—keep your eyes peeled for sea otters, harbor seals, and various seabirds.
🐦 Wildlife Etiquette (Mile 4.2-5.8):
This section passes through active seabird nesting zones from April through July. Stay on the trail and maintain at least 100 feet from nesting areas. Disturbing nesting birds is illegal and can result in fines. For comprehensive wildlife safety guidelines, review our detailed guide.
The second tidal crossing (mile 7.8) is longer and more challenging than the first. It's approximately 400 yards of rocky, wave-washed terrain. Timing is even more critical here, as there are fewer escape options if you're caught by rising water.
🚨 Safety Warning:
Never attempt the tidal crossings during incoming tide, even if it looks passable. Waves can surge unexpectedly, and the rocks become extremely slippery. If in doubt, wait for the next low tide window. Your safety is more important than sticking to a schedule.
The final 2 miles return to the trailhead through coastal forest. The trail is well-maintained but can be muddy after rain. Proper footwear with good grip is essential, especially for the rocky tidal sections.
Black bears are common in this area. Bear canisters are mandatory—no exceptions. All food, scented items (toiletries, trash), and cooking equipment must be stored in approved bear canisters when not in use.
For detailed bear safety protocols, including what to do during encounters, see our comprehensive wildlife safety guide.
From April 1 through July 31, certain sections of the trail pass through active seabird nesting areas. These zones are clearly marked. Stay on the trail, keep dogs leashed (if permitted), and maintain distance from nesting sites. Disturbing nesting birds can result in significant fines and is harmful to vulnerable populations.
This is a sensitive coastal ecosystem. Pack out all trash, including used toilet paper. Human waste must be buried at least 6 inches deep and 200 feet from water sources, trails, and campsites. Never wash dishes or yourself directly in streams or the ocean—use a bucket and dispose of gray water at least 200 feet from water sources.
