Technical to start but eases off after the bridge, at which point you just need low gears. Few drops at the end if heading down. I'd say if you're pretty skilled you can make it up or down on a gravel bike, otherwise take suspension.

A little bumpy underwheel, probably fine on bigger tyres but a slightly sloggy way to enter or exit Edinburgh. Better entering as its slightly downhill all the way from Balerno

Pretty big persistent puddles, often quite deep or rough underwheel. The sort of path which is doable with a sendy spirit on a gravel bike, but would be much more fun on a hardtail. The path you join if heading west is great fun.

I'd recommend avoiding it if on a bike. It's a narrow path used by a variety of modalities (dogs, prams, people on mobiles, bikes too) in both directions. Some sections have tree roots vigorously breaking out of the tarmac and can get pretty bumpy. Sections by bridges are narrow and impossible to see around.

Harlaw Reservoir is a popular spot for outdoor activities including walking, fishing, and wildlife watching. One of the highlights is a small embankment on the far side of the reservoir which offers stunning views of Threipmuir Reservoir. On weekends visitors you can get your hands on some homemade crepes from a local van parked near the Harlaw House Visitor Centre.
