Plan Your Visit
⚠️Remoteness & SafetySelf-sufficiency required
🧭 NPS's own framing: thorough preparation is what separates "the adventure of a lifetime" from tragedy. Help may be days away, there's no cell service, and flight pickups can be delayed by weather — pack extra food and fuel. Hazards include high winds and large waves on the lakes, unbridged river crossings, aviation risk (most visitors arrive by small plane), shared bear habitat, and dense brush requiring bushwhacking.

🛩️Access & EntryNo entrance fee
✈️ NPS is direct: "Lake Clark is not on the road system and travel takes place primarily by small plane." Port Alsworth, the main hub, has "no grocery stores" and is not connected to any road system. Most visitors arrive on wheeled small planes at one of two gravel airstrips; floatplanes also land in Hardenburg Bay. Air taxis depart from Anchorage (~120 air mi), Homer (~65 air mi), and Kenai/Soldotna, roughly 1–1.5 hours flight time. NPS directions ↗

🪵Dick Proenneke's CabinNational Historic Site
📖 Richard "Dick" Proenneke arrived at Twin Lakes in 1968 at age 51 and hand-built his 11×15 ft log cabin that first summer, living there roughly 31 years and documenting his life — the basis for the book "One Man's Wilderness" and the PBS documentary "Alone in the Wilderness." Listed on the National Register of Historic Places in 2007; he willed the cabin to NPS. Open for self-guided tours daily 10am–4pm in summer, with rangers on-site. NPS cabin history ↗
🏕CampingNo permit required
No developed drive-in campground exists — the park isn't on the road system. Backcountry permits for camping and hiking are not required, though bear-resistant food canisters ARE required for overnight trips (loaned free at the Port Alsworth ranger station). Visitors are strongly encouraged, though not required, to file an itinerary with the visitor center. NPS backcountry info ↗
