What Hidden Lake offers and how to find it

Hidden Lake sits in the backcountry of the Kenai Peninsula, accessible only by foot or floatplane—there is no road to the water. The lake holds a population of cutthroat trout and Dolly Varden char in a setting that rewards the effort to reach it. The trout run smaller than what you'll find in the peninsula's road-accessible lakes, typically 8 to 14 inches, but the fish are eager and the solitude is genuine.

Getting there requires either a 3- to 5-mile hike from the nearest trailhead or a floatplane charter from Soldotna or Kenai. The hike is the budget option but demands fitness and good weather; the floatplane costs $300 to $500 per person round-trip but puts you on the water in 20 minutes. Most anglers who fly in plan a 2- to 3-day stay to justify the cost. The hiking route is less crowded but the trail can be muddy and brush-choked depending on the season.

Key Takeaways

  • Hidden Lake holds cutthroat trout and Dolly Varden in the 8- to 14-inch range, with eager fish that respond well to small flies and spinners.
  • Access is by floatplane charter ($300–$500 per person) or a 3- to 5-mile hike from the trailhead; no road access exists.
  • The lake is best fished from June through September, with July and August offering the most stable weather and longest daylight.
  • Bring a small raft, float tube, or be prepared to wade from shore; the lake has no rental services or facilities.
  • Alaska Department of Fish and Game regulations allow two trout per day; check current rules before you go, as they can change year to year.

When to fish and what the weather does

Hidden Lake opens to fishing in June, when the ice clears and water temperatures begin to climb. Early season (June and early July) can be hit-or-miss—cold water slows the bite, but fewer anglers are around. July and August are the peak months: water warms, insects hatch more reliably, and the long daylight hours let you fish from dawn past 10 p.m. September remains productive but weather becomes unpredictable, with rain and wind increasing the risk of floatplane delays.

Weather on the Kenai Peninsula changes fast. Morning fog and afternoon wind are common even in midsummer. If you fly in, build an extra day into your schedule in case weather grounds planes. The lake itself is exposed with few natural windbreaks, so afternoon winds can make fishing difficult and floatplane pickups risky. Bring rain gear and a warm layer regardless of the forecast.

Tackle and techniques that work

Small flies work best because the trout are not large and the water is clear. Dry flies—Adams, Elk Hair Caddis, and small Stimulators in sizes 12 to 16—draw strikes during the evening rise. Nymphs fished under an indicator (Pheasant Tail, Hare's Ear) are more consistent throughout the day. Cutthroat will also take small spinners (size 0 or 1 Mepps or Panther Martin) and small spoons, which are easier to cast if you're not a fly angler.

The Dolly Varden are less selective and will hit larger streamers and darker flies. Fish the drop-offs and deeper water along the lake's edges in the afternoon; in early morning and evening, cruising fish hunt the shallows. If you wade, move slowly and watch for rises. The water is cold year-round, so hypothermia is a real risk if you fall in—wear a life jacket if you're in a float tube or raft.

Getting there by floatplane

Floatplane charters operate from Soldotna and Kenai. Redington Aviation, Talkeetna Air Taxi, and Rust's Flying Service all run trips to remote Kenai Peninsula lakes. Call ahead to confirm Hidden Lake is on their route and to book a round-trip flight; most charters require a minimum party size (usually two to four anglers) or charge a per-person rate. Flights typically depart early morning to maximize your time on the water.

Bring only what fits in a soft bag—floatplanes have strict weight limits. Pack your rod in a tube or hard case, but leave the case behind if possible. Coordinate your pickup time with the pilot before you land; if weather prevents pickup on your scheduled day, you may have to wait at the lake or hike out. Most charter services have a weather policy that allows rescheduling without penalty, but read the fine print.

The hiking route and trailhead logistics

The main trail to Hidden Lake begins near the town of Sterling, roughly 90 minutes south of Anchorage. The trailhead is marked but parking is limited—arrive early or plan a weekday trip. The hike gains elevation gradually but the trail is often wet and overgrown, especially in July and August when brush is thick. Expect 4 to 5 hours to reach the lake if you're moving at a steady pace; return hikes take longer because you're tired.

Bring a topographic map and a GPS device or smartphone with offline maps downloaded. Cell service is unreliable. The trail crosses streams and boggy sections where a misstep can twist an ankle. Wear waterproof boots and gaiters. A walking stick helps with balance on muddy sections. If you're camping overnight, set up camp away from the water to avoid disturbing fish and to reduce bear encounters. Store food in a bear canister or hang it from a tree.

Regulations and what you need to know before you go

Alaska Department of Fish and Game sets the rules for Hidden Lake. The current limit is two trout per day, but regulations change and vary by water. Check the Alaska Sport Fishing Regulations booklet (available online at adfg.alaska.gov) before your trip. You must have a valid Alaska fishing license; nonresidents can buy a 14-day license online or at sporting goods stores for around $60.

No special permits are required for Hidden Lake itself, but if you're flying in on a floatplane, the charter company may have additional rules about group size or booking. The lake sits on public land managed by the Alaska Department of Natural Resources, so camping is allowed but fires are not permitted in many areas—check current restrictions. Leave no trace: pack out all trash, including fishing line and leaders.

Gear you'll need to bring

A float tube or small raft is nearly essential because shore fishing is limited and wading is slow. A 4- to 6-pound float tube weighs little and packs small. Bring fins, a life jacket, and a small anchor or stake to hold position. If you hike in, a packable raft (like an Alpacka or similar ultralight model) adds weight but opens up the entire lake. A 5-weight fly rod is standard; if you're using spinning gear, bring a medium-light rod and 4- to 6-pound line.

Pack a headlamp, rain jacket, fleece, and a warm hat—even in July, evening temperatures drop into the 40s. Bring more food than you think you'll need; hiking burns calories and there's nowhere to resupply. A water filter or purification tablets let you drink from the lake. First aid kit, sunscreen, and insect repellent are not optional. If you're flying in, coordinate with your charter about what they can provide (some offer coolers or basic camping gear for an extra fee).

Frequently Asked Questions

Can I fish Hidden Lake without a float tube or raft?

Yes, but you'll be limited to the shallows and drop-offs you can reach by wading. A float tube or raft lets you cover more water and reach deeper structure where larger fish hold. If you're hiking in and weight is a concern, a packable float tube (3 to 4 pounds) is a compromise between mobility and range.

What's the difference between cutthroat and Dolly Varden at Hidden Lake?

Cutthroat trout have a red or orange slash under the jaw and are more selective feeders; they prefer small flies and nymphs. Dolly Varden char lack the slash, are darker overall, and will hit larger, darker patterns. Both are good eating, though Dolly Varden tend to be oilier. Check regulations—some waters have different limits for each species.

Is Hidden Lake safe to fly into if I've never been there before?

Yes. Floatplane pilots know the lake and land there regularly. They'll brief you on hazards, show you where to camp, and confirm your pickup time. The risk is weather delays, not the landing itself. Build an extra day into your schedule and have a backup plan if you can't fly out on time.

How much does a floatplane charter actually cost?

Round-trip charters run $300 to $500 per person, depending on the operator, distance, and group size. A party of four splits the cost better than a solo angler. Call multiple operators to compare; some offer discounts for weekday trips or off-peak dates.

What happens if I get injured on the hike or at the lake?

Cell service is unreliable. If you're hiking, tell someone in town where you're going and when you'll return. Carry a personal locator beacon (PLB) or satellite communicator if you're concerned about rescue. If you fly in, the charter company knows your location and can alert authorities if you miss your pickup. A first aid kit and knowledge of basic wilderness first aid are essential.
