Water taxi to Grewingk Glacier

The trip

The M/V Inlet Express leaves the Homer Harbor and crosses Kachemak Bay in 15 to 20 minutes. We drop you at the Glacier Spit landing, where the Grewingk Glacier Trail starts. It’s a flat 3.2-mile walk through cottonwood forest and along Kachemak Bay shoreline to the glacier lake — one of the most family-friendly trails in the state park.

At the lake you’ll see icebergs calved from the glacier drifting across a milky-blue meltwater pool. The glacier itself sits at the far end. On calm days you can hear it crack.

The two Grewingk Glacier trailheads: Glacier Spit vs. Saddle Trail

Kachemak Bay State Park has two trailheads that access Grewingk Glacier, and the choice matters for tide, weather, and difficulty. Our recommendation for almost every trip is to drop at Glacier Spit and pick up at Saddle Trail — the classic loop.

Glacier Spit trailhead — the easy way in

Glacier Spit is the flat, gravel-beach landing directly across the bay from Homer. It's the primary trailhead most visitors use and the one we recommend for first-timers, kids, and anyone who wants a low-effort day. The trail from Glacier Spit is a nearly flat 3.2 miles one-way to Grewingk Glacier Lake, gaining only about 200 feet of elevation across mature cottonwood forest and alluvial flats. Morning drop-offs at Glacier Spit are usually calmer — afternoon winds can pick up on that side of the bay.

Please note: We drop at Glacier Spit but we do not pick up there unless by special arrangement. Plan your route to exit at the Saddle Trail beach.

Saddle Trail trailhead — our standard pickup point

The Saddle Trail landing is a rocky beach a couple of miles east of Glacier Spit. From the beach the trail climbs steadily over a saddle in the coastal ridge before descending to meet the Glacier Lake Trail. It's about half a mile from the beach to the junction with the main trail, then another 1.5 miles from that junction to the glacier lake. Total loop distance — Glacier Spit drop, up to the lake, and out over the saddle to your Saddle Trail pickup — is about 5.2 miles with roughly 800 feet of elevation gain. You finish with an easy downhill to the beach.

The tramway option — a fun add-on

About 1.5 miles into your hike from Glacier Spit, there's a junction where a left turn takes you toward a hand-pulled tramway that crosses the outflow of Grewingk Glacier Lake. The outflow is too swift and too deep to wade, so the tramway is the only way across. Hikers heading to longer routes on the far side of the outflow use it as their gateway.

Even if you're not doing an extended trip, riding the tramway is a fun option that adds about 1 mile out to it and 1 mile back. If you have the courage, the strength, and the time, go out on the trolley a ways — it's one of the more memorable moments on a Grewingk day. Bring gloves to protect your hands while pulling on the rope.

What you'll see on the Grewingk Glacier hike

Kachemak Bay State Park is Alaska's oldest state park and one of the most biologically rich stretches of coastline in North America. The 3.2-mile trail to Grewingk Glacier Lake is short, but every mile passes through a different piece of that landscape.

The forest section

The first 1.5 miles from Glacier Spit wind through mature Sitka spruce and black cottonwood — some of the largest cottonwoods in Kachemak Bay State Park. In summer the understory is dense with ferns, devil's club, and highbush cranberry. Bald eagles nest in the tallest cottonwoods and you'll often hear their high whistled calls above the trail. This is also prime moose habitat: give any moose you see plenty of space and keep dogs leashed.

The alluvial flats

Around the 1.5-mile mark the trail opens onto broad alluvial flats — glacial outwash gravel from thousands of years of Grewingk retreat. The view opens up here to the surrounding peaks and you get your first look at the glacier itself in the distance. Wildflowers bloom on the flats through July: fireweed, lupine, and Alaska cotton in the wet spots.

The glacier lake

The trail ends at the shore of Grewingk Glacier Lake, a milky turquoise meltwater lake fed directly by the glacier's terminus. Icebergs calve from the glacier face and drift across the lake, sometimes grounding on the near shore where you can walk right up to them. The color of the lake comes from suspended glacial silt — "rock flour" — ground fine by ice moving over bedrock over thousands of years. On calm days you can hear the glacier cracking and groaning across the water.

Wildlife you might see

Bald eagles are common. Black bears and moose are present in the park year-round — sightings are less frequent than you'd expect because the trail is well-traveled, but always carry bear spray and make noise on brushy sections. In the bay on the crossing over, watch for sea otters, harbor seals, harbor porpoises, and (in July and August) humpback whales.

Best time of year to visit Grewingk Glacier

Kachemak Bay State Park is accessible by water taxi from mid-May through mid-September. Here's what to expect month by month.

May and early June — quiet, cold, dramatic

Early season is the least-crowded window. Snow can still linger on the higher trails and along the shaded forest sections into early June, but the main Glacier Spit route is usually clear by mid-May. Water temperatures are still cold, so keep your feet dry. Wildlife activity is high — bears are just emerging, and eagles are actively nesting.

Late June through July — peak season

This is our busiest window and for good reason: 18+ hours of daylight, average highs in the mid-60s°F, and wildflowers at peak bloom on the alluvial flats. Book 2–4 weeks ahead for weekend trips in July. Trails can be muddy after rain but are otherwise in great shape.

August — the shoulder

August is our favorite month for Grewingk. Bug pressure drops significantly after the first cold nights. Salmon are running in the streams. Fireweed goes to seed and the flats turn crimson. Days are still long. Crowds thin out mid-month.

Early September — end of season

First frost arrives, the cottonwoods go gold, and the light gets low and golden. Fewer trips run per day, so bookings should be firmed up a week ahead. Bring warmer layers — mornings can be in the 40s°F.

Tides and weather

Kachemak Bay has extreme tides — up to 28 feet of swing. Very low tides can make the Glacier Spit landing dry-out at the far edge, which sometimes means a slightly longer walk from the boat to shore. Weather across the bay is highly local: Homer can be sunny while the state park is fogged in, and vice versa. We monitor conditions daily and reschedule if it's genuinely unsafe.

Kachemak Bay State Park — the setting for Grewingk

Grewingk Glacier is one of several glaciers within Kachemak Bay State Park, a 400,000-acre wilderness across the bay from Homer that includes 80 miles of coastline, dozens of hiking trails, and public-use cabins. The park was established in 1970 and is Alaska's first legislatively designated state park. It's accessible only by boat or floatplane — there are no roads.

The park is free to enter and does not require permits for day hiking. Camping is allowed at designated sites near Glacier Spit and at Right Beach. Bear-resistant food storage is required. Fires are permitted below the high-tide line only. There is no potable water anywhere in the park — carry all the water you'll need. Cell service is spotty to nonexistent on the trail.

For extended trips, the state park operates several public-use cabins that can be reserved through Alaska DNR reservations. Popular options within a reasonable hike of Grewingk include the Halibut Cove Lagoon cabins and the Right Beach cabin.

How long to book and which route to choose

Every Grewingk day trip is a variation on the same drop — Glacier Spit — and the same pickup — Saddle Trail. What actually changes is the route between them and how much time you want at the lake. Three real choices:

The classic loop — 4.5 hours

Drop at Glacier Spit, hike the flat 3.2 miles to Grewingk Glacier Lake, spend about an hour at the lake, then exit over the saddle for pickup at Saddle Trail. About 5.2 miles total with 800 feet of climb. This is what most groups book and it's what we recommend for first-time visitors.

The classic loop with the tramway detour — 6 hours

Same loop, plus the 1-mile-out-and-1-mile-back tramway spur described above. Adds about an hour to the day. This is the right choice for families, groups that want options, or hikers who prefer a more relaxed pace with time to enjoy the tramway experience.

Saddle Trail up-and-back — short and steep, 3 to 4 hours

The one exception to the loop is going up and back over the Saddle Trail without doing the flat approach from Glacier Spit — drop and pick up at Saddle Trail. This shortens the hike to about 4 miles total but the climb is steeper and the scenery is less varied — you skip the cottonwood forest and the alluvial flats. A strong hiker who's moving out can do it in around 2 hours of actual walking time. Choose this if you want a shorter, harder day and you don't need to see everything.

See the itinerary section below for exact departure and pickup timing on the two loop options. If you're doing the up-and-back, tell us when you book and we'll pick the right pickup time.

Sample Grewingk Glacier itinerary

Our schedule makes it simple: choose your options and your group's speed, add the right number of hours, and check the schedule for a corresponding pickup. Everything's laid out on the booking pages so you don't need to call and haggle.

Your first option is to depart the Homer Harbormaster at 8:00 AM, which gets you started on the trail about 8:30 AM. You can choose one of our later departures and do your own math, but this itinerary assumes you chose the 8:00 AM boat.

• 8:00 AM — Depart Homer Harbor. The crossing to Glacier Spit takes 15 to 20 minutes.
• 8:30 AM — On the trail. Head into the forest section from Glacier Spit toward the lake.
• 10:30 AM — At the lake. Most groups reach the glacier lake by mid-morning. Plan on about an hour at the lake for lunch and photos.
• 11:30 AM — Start out over the saddle. About 1.5 hours to your Saddle Trail pickup.
• 1:00 PM — Saddle Trail pickup if you're on the 4.5-hour classic loop.
• 2:30 PM — Saddle Trail pickup if you added the tramway detour — that's the 6-hour version.

This is just an example. Choose your departure from Homer Harbor and add 4.5 hours (classic loop) or 6 hours (loop with tramway) to find your corresponding pickup time on our schedule. Because of our other runs during the day there are gaps between pickup options, so check the schedule to see them clearly.

When you book, you must book each leg separately — the drop-off and the pickup as two bookings. We're required to do it that way, which turns out to be a plus: you get fantastic choices instead of a fixed round-trip.

Make a day of it

Add even more time if you want. On a sunny day that might be just lounging with friends. Another great option: bring an inflatable paddleboard or kayak so you can go explore the glacier from the water. One bit of caution — make sure your skills and your boat match the task. The lake water is only 33°F.

What to pack for Grewingk Glacier

The right kit for a Grewingk day trip is simple, but a couple of items are non-negotiable in Alaska.

Essentials

• Layers. Base layer, insulating mid-layer (fleece or puffy), and a wind/rain shell. Temperatures swing 20°F between the boat crossing and the trail.
• Rain jacket. Even on a sunny morning. Kachemak Bay weather changes fast.
• Sturdy footwear. Hiking boots or trail runners. The trail is gentle but has roots and rocks. Waterproof shoes are a plus for muddy sections.
• Water — at least 2 liters per person. There is no drinkable water on the trail. All streams cross glacial-fed drainages and contain sediment.
• Lunch and snacks. You'll be off the boat 4.5 to 6 hours. Sandwiches, energy bars, fruit, nuts.
• Sun protection. Sunscreen, sunglasses, brimmed hat. Reflected light off the glacier and lake is intense.
• Bear spray. Standard practice in any Alaska state park. We can point you to the Homer stores that sell it if you're flying in.
• Gloves if you plan to try the tramway — the rope is rough on bare hands.

Nice to have

• Trekking poles (helpful on the Saddle Trail descent)
• Binoculars (for eagles and glacier detail)
• Camera with a wide-angle lens
• Small first-aid kit
• Trash bag (leave no trace — pack out what you pack in)

What you don't need

No park permits, no reservations for the trail itself, no bear canister for a day hike, no bug net (bug pressure is moderate and drops with any wind). Kachemak Bay State Park is one of the least regulated wilderness experiences in Alaska — that's part of the charm.
