Backpacking in Reservoir
👀 For curious travelershike ranked #9
By Johan Kruseman 🇳🇱 | Updated June 9, 2026

Most people hear “Reservoir walk” and picture a flat, lazy loop around some water. Not here. Reservoir sits inland in central Guernsey, between St Peter Port and the island’s quieter western lanes, and the trail actually makes you work. You drop and climb through damp, tree‑tunneled paths, skirt the water’s edge, then punch up short, steep sections that wake your legs up fast. The payoff is moody woodland, mirror‑calm water, and a sense that you’ve slipped off the tourist circuit without needing a car. Buses from St Peter Port get you close, and the route is short and moderate, but it can feel repetitive compared with Guernsey’s coastal cliff paths, which deliver bigger views and more drama for roughly the same effort.

  • Mirror-flat water and ever-changing light — The reservoir’s calm surface turns into a giant mirror at dawn and dusk, so you get those dramatic sky reflections without trekking to a cliff. Cloudy days are just as good—soft, diffuse light and moody photos. Easy to find a quiet bench and watch the light shift over 10 minutes.
  • Birdlife and reedbed edges — Reed fringes and shallow margins concentrate wildlife: ducks and waders are regulars, and on quieter stretches you might spot a heron or a flash of kingfisher. Small hides and low paths bring you close without scaring everything off.

  • Short but varied trail textures — Unlike a long coastal slog, the Reservoir loop packs mixed terrain into a compact route: gravel paths, grassy banks, a few muddy patches and boardwalks. That variety keeps the walk interesting and makes it perfect for a quick outing or a slow, relaxed wander.
  • Scattered wartime and local history clues — Look for concrete relics, stone boundary markers and info boards tucked into the scrub that tell small stories about island life and occupation. They’re low-key and atmospheric rather than museum-perfect, which I prefer — feels like walking through living history.
  • Channel glimpses and island horizons — From higher spots on the loop you can pick out the Channel and nearby islets on a clear day. The contrast between inland water and the distant sea is a neat reminder you’re on a small island — great for a pause and a snack.

🌤️ When to go?Weather, crowds, and seasonal trade-offs


  • Weather: Guernsey’s mild maritime climate means the Reservoir trail stays accessible year-round, but spring and early autumn offer the best balance—expect crisp, clear days without the summer’s sticky humidity or winter’s damp chill.

  • Temperature: In peak hiking months, temperatures hover between 12-18°C (54-64°F), perfect for sustained effort without overheating or freezing your fingers off.

  • Daylight Hours: Late spring through early autumn stretches daylight to 14-16 hours, giving you plenty of time to push your pace, soak in the views, and still catch a sunset without rushing.

  • Crowds: Summer weekends bring local families and tourists, turning the trail into a social scene. For a quieter, more solitary trek, aim for weekdays in shoulder seasons.

  • Seasonal Activities: Spring blooms

  • Seasonal Activities: Spring blooms and autumn foliage add a natural spectacle, while summer invites waterside picnics and post-hike dips—each season flavors the experience differently.

  • Price Fluctuations: Accommodation and transport costs spike in summer. Booking in shoulder seasons can save cash and avoid the crush, letting you spend more on gear or a celebratory pint.


Pro-tip: Hit the Reservoir trail in late April or September—cool temps, fewer crowds, and daylight that lets you savor every step without racing the clock.

The Reservoir hike in Guernsey is a straightforward trek, but don’t let that fool you into complacency. Weather can shift quickly; a sunny morning can morph into a chilly drizzle. Dress in layers and keep a waterproof jacket handy. The terrain is mostly well-maintained, but watch your footing on the occasional rocky sections.

Wildlife is present, so keep your distance from any grazing sheep or curious rabbits. They’re part of the charm, but respect their space.

Timing matters; early mornings offer tranquility and fewer crowds. Carry enough water and snacks to fuel your journey. Embrace the rhythm of the trail, and when you reach that serene view over the water, you’ll feel every step was worth it.
