Avalanche Lake Trail

Avalanche Lake Trail is a cedar-forest and gorge hike to a broad glacial lake beneath steep cliffs. The mileage matters, but the real character of the route comes from boardwalk, forest roots, rocks, creek gorge, bears, and busy shoreline. Plan the entire outing—parking, trailhead preparation, movement time, breaks, changing conditions, and the return—rather than treating the destination as the only part of the hike.

The details below turn the route into a usable day plan. They explain the trailhead, major landmarks, permits, likely trouble points, pace, gear, and a shorter objective. Operating rules and conditions can change, so compare the plan with the managing agency's current alert before leaving for Trail of the Cedars area.

Trail Conditions and Effort

The route is best understood as out and back, with boardwalk, forest roots, rocks, creek gorge, bears, and busy shoreline. Those details affect speed, footwear, balance, water use, and whether every member of the group can complete the same movement on the return. A short trail with chains, deep sand, submerged rocks, ice, or steep stone steps can require more judgment than a longer smooth path.

Route walkthrough

1

Trailhead and First Section

Use the level Trail of the Cedars boardwalk to reach Avalanche Gorge. Pause at the end of this stage to compare actual time, water use, weather, and group condition with the plan. Confirm the next junction before moving, because a familiar-looking trail or a line of footprints can lead away from the intended route.

2

Main Route

Follow Avalanche Creek through dense forest on a steady climb. Pause at the end of this stage to compare actual time, water use, weather, and group condition with the plan. Confirm the next junction before moving, because a familiar-looking trail or a line of footprints can lead away from the intended route.

3

Turnaround and Return

Arrive at the near shore of Avalanche Lake and remain on durable shoreline areas. Pause at the end of this stage to compare actual time, water use, weather, and group condition with the plan. Confirm the next junction before moving, because a familiar-looking trail or a line of footprints can lead away from the intended route.

Trailhead access and arrival

Parking is limited at Trail of the Cedars; use transit where available and follow current bear guidance. Carry water; pets are not allowed.

The starting point is Trail of the Cedars area. Save the trailhead, route map, and permit proof offline. Arrive with enough time to solve a full lot or shuttle wait without rushing. Never invent roadside parking, cross a closed gate, or start late because the drive was longer than expected. A full access point is a reason to use the backup route selected at home.

Permit, services, and current rules

Park entrance and any current road-corridor reservation rules apply.

Plan for the Return Trip

Outward leg

Return leg

The Avalanche Gorge viewpoint from Trail of the Cedars is the shorter option when time or weather is limited. The return can be uphill, hotter, darker, more crowded, harder on tired knees, or slower through water and loose ground. Keep food, water, attention, and daylight in reserve. Make the turnaround decision before anyone is depleted enough to argue for continuing.

Season, weather, and daily timing

Hazards to manage deliberately

The main concerns are bears, wet roots, crowding, cold water, falling trees, and road access limits. Name the hazards before starting so every person understands what would trigger a turnaround.

  • Footing: Slow down on wet rock, loose stone, roots, sand, snow, ice, or submerged surfaces. Use poles or traction only when practiced and appropriate.
  • Weather: Leave ridges, open summits, river corridors, and slot canyons before storms arrive. Thunder, rapidly rising water, or sudden wind is an action signal.
  • Heat and cold: Protect skin, carry layers, and watch for headache, nausea, confusion, shivering, or declining coordination. Do not wait for collapse.
  • Navigation: Confirm every important junction on the return. Crowds, footprints, and a phone dot are not substitutes for an offline map.
  • Wildlife: Give animals space, secure food, control pets where allowed, and follow local bear, bison, goat, snake, or nesting-season guidance.
  • Group management: Stay together, place a capable adult at the rear, and never leave a struggling person alone so others can reach the destination.

What to carry

  • Official route map, offline navigation, charged phone, cable, and backup battery.
  • Enough water for the full route, current conditions, and an unexpected delay.
  • Food for the planned time plus a reserve portion kept for the return.
  • Weather layers, rain or wind shell, hat, sunglasses, sunscreen, and dry insulation where needed.
  • Headlamp, first aid, blister care, personal medication, whistle, and emergency shelter.
  • Footwear and route-specific equipment for boardwalk, forest roots, rocks, creek gorge, bears, and busy shoreline.

Who should choose another hike

Leave enough margin to handle the part of the day that was not in the itinerary.
