Porth Reservoir Loop

Starting from the car park just off the A3059 near Newquay, Cornwall, the Porth Reservoir Loop offers a scenic 6 km (about 3.7 miles) circuit with an elevation gain of approximately 200 metres (656 feet). The trailhead is easily accessible by car, with parking available at the Porth Reservoir Nature Reserve. For those using public transport, buses from Newquay town centre stop at the nearby Trevelgue Road, a short walk from the reservoir entrance.Getting Oriented and Early Highlights
The loop begins by skirting the edge of Porth Reservoir, a tranquil body of water surrounded by lush woodland and open meadows. Early on, you’ll pass through a mix of shaded paths and open stretches, with the gentle sound of water and birdsong setting the tone. The reservoir itself is a haven for birdlife—look out for herons, kingfishers, and, in spring and summer, swallows swooping low over the water.Woodland and Meadow Sections
At around 1.5 km (just under a mile), the trail enters denser woodland, where the path undulates gently, gaining elevation as you move away from the water’s edge. Here, the undergrowth is thick with ferns and bluebells in late spring, and the canopy overhead is alive with the calls of woodland birds. The path can be muddy after rain, so sturdy footwear is recommended.Emerging from the woods at about 3 km (1.9 miles), the trail opens onto rolling meadows with sweeping views back toward the reservoir and, on clear days, glimpses of the Cornish countryside beyond. This section is particularly rich in wildflowers during late spring and early summer, attracting butterflies and bees.Historical and Natural Points of Interest
The area around Porth Reservoir has a history tied to Cornwall’s agricultural and mining past. While the reservoir itself was constructed in the mid-20th century to supply water to Newquay, the surrounding land bears traces of old field boundaries and hedgerows that date back centuries. Keep an eye out for remnants of stone walls and the occasional standing stone, hinting at the region’s ancient past.Final Stretch and Return
The loop curves back toward the reservoir at around 4.5 km (2.8 miles), descending gently through mixed woodland. The final section follows the water’s edge, offering peaceful views and the chance to spot waterfowl and, occasionally, otters. Benches along this stretch provide good spots for a rest or picnic.Navigation and Safety
The trail is well-marked, but carrying a digital map on HiiKER is recommended for real-time navigation and to ensure you stay on the correct path, especially at junctions where smaller side trails branch off. Mobile signal is generally reliable, but it’s wise to download maps in advance.Wildlife and Seasonal Considerations
Throughout the year, the loop offers varied wildlife viewing opportunities. In autumn, the woods are rich with fungi, while winter brings flocks of overwintering birds. The trail is suitable for most hikers with moderate fitness, but the woodland sections can be slippery in wet weather.With its blend of water, woodland, and meadow, the Porth Reservoir Loop is a rewarding walk for those seeking a taste of Cornwall’s natural beauty and subtle historical echoes, all within easy reach of Newquay.
