About Sullivan Lake National Recreation Trail
Sullivan Lake National Recreation Trail is a 6.7 km hiking route in Washington, United States. It climbs roughly 147 m (482 ft) along the way. Most people take around 1 hr 36 min at a comfortable pace, plus stops. It sits firmly in moderate territory: enough climbing to feel like a proper day out, never enough to become a slog.
The water is the anchor of the route, still enough on calm mornings to mirror everything above it.
It runs point to point, so arrange transport at the far end or plan a return leg before you set off. It is not consistently waymarked, so carry a map or a downloaded track rather than relying on signs.
Spring through autumn is the natural window, and shoulder season means fewer people on the narrow sections. The route is maintained by Colville National Forest.
In short, Sullivan Lake National Recreation Trail suits regular walkers who want a full day without technical ground. Dog access is not formally recorded here, so check locally before bringing one.
Plan around this route’s details
- Start, finish and return
- The recorded 6.7 km line has different endpoints. Confirm travel from the finish before setting out; that return journey is additional to the mapped route.
- Climbing in context
- The recorded ascent averages approximately 22 m of climbing per kilometre across the whole route. This is climbing density, not trail gradient: climbs and flatter sections may be unevenly distributed.
- What needs a separate check
- This record does not establish surface, dog access, wheelchair access. Check any of these that affect your group. Current closures, access arrangements and transport are not verified by the route line.

Your walking-time scenario
Adjust the example pace and allowances to explore your own plan. This calculator uses your inputs, so it may differ from the directory’s headline estimate.
Calculated walking time including your allowances
2 hr 25 min
100 min for distance + 15 min for ascent + 30 min allowance.
Formula: distance ÷ pace × 60 + ascent ÷ 100 × climbing allowance + stops. Travel to and from the route is additional. Terrain, descent, weather and navigation are not modelled. These results do not establish route suitability. Read the time-planning guide.
Recorded route measurements
The route is normally walked in the direction described below. The gradient is spread evenly, so there is no single section that dictates your pace. Because the finish is away from the start, check return transport before committing to the second half.

Tips from the trail
- Early morning and late afternoon give the best light and the quietest paths.
- Aim for april to october for the most reliable conditions.
- Calm mornings give mirror reflections on the water, so it is worth being there early.
- Download the track to your phone before you leave. Signal is not guaranteed.
- Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.
Warnings
- Outside the main season expect snow, ice or closed access on the higher sections.
Safety
Emergency services in United States are reached on 911. Tell someone your route and expected finish time before you set off, particularly if you are walking alone. Mobile coverage is generally usable along this route, but do not rely on it as your only plan. If the weather deteriorates, descending the way you came is almost always the safer option.
What to bring
- Comfortable, broken-in hiking shoes or boots
- Weatherproof jacket
- At least 1.5 litres of water
- Sun hat, sunglasses and high-factor sun cream
- Small first aid kit including blister plasters
Photography
Overcast light suits this route better than harsh midday sun, especially under tree cover. Take the shot on the way out. Conditions rarely improve by the time you come back past. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
