Info on 3 routes from about 5 years ago when I rode them. There is loads of stuff on Raasay built (or rediscovered) by Steve White and used in the Raasay Rumble back in 2007 – try asking at the outdoor centre which I believe is temporarily relocated in Borodale House hotel.
1) Glen Sligachan ride (OS sheet 32)- start at Sligachan hotel and head S down the main Glen path to Camasunary. This starts off rocky and technical for the first bit, with a lot of drainage ditches for the first 2 or 3 km. Frist time in the dry I thought it was awesome, second time in the wet it was pretty grim and slidy. The track gets better around loch an Athain and we followed the lower of the two marked on the map from beside Loch na Creitheach (GR 514212). This takes you down to Camasunary bay and can get a bit wet in places near the end but the bay is a lovely spot to have a rest. That stretch is about 12km of pure singletrack heaven if you're ok with rocks and the ground isn't sodden! Scenery is second to none, awesome views of the Cuillin.
From there it's a hard push out to the west, up to Am Mam. This is really rubbly and steep and most people would struggle to ride it all. After the hairpin (523189) it becomes a bit more rideable and the descent is a scorcher. From there it's road to the head of Loch Slapin (566224) then a bit of offroad through Strath Mor. The track on the ground seems to go E of Lochain Stratha Mhoir; we followed a stream bed to pick up the rough remains of the track at about 565257. This section is really grim and muddy (and was even last year when most of the route was dry) and you'll be glad to see Luib.
We've always done it as a 2-car job, the alternative is to go round the coast by Moll, the main road has a big climb and carries a lot of traffic (relatively!) so not sure I'd fancy biking it. This one is one of the best bike rides I've ever done, takes most of a day but the Glen Sligachan section is awesome – jawdropping scenery and riding!
2) Boreraig Route nr Broadford. We started at Cil Croisid (617207) and headed south on the obvious track towards Boreraig. This is a good track to start with (was a quarry access road I think) then becomes a raised causeway above the bog as you descend into Boreraig -superb riding, cracking views out to sea. From Boreraig (an abandonned clearance village), you head W along the coast on a raised beach platform (mostly rideable) – stay low and follow the shoreline until an obvious track forces you up the cliff. We went up too early at a big sticky-out bit of cliff just after the village and had to descend again, and round to Suisnish(another cleared village), things a bit vague once you're on top of the cliffs but keep the sea to your left and when you get to the village, aim for the house with the red roof as that's the start of your landy track back to
the road near Torrin. Then head E along the singletrack road back to the start. It's a quality short ride and the descent to Boreraig is the best bit. 9.5/10 for rideability, only one short bit up the cliff defeated our strongest rider.
3) Raasay Just headed up the road to the north – the last few km "Callum's Road" are the best tarmac I've ridden on, steep ups and downs. Built by a postman singlehandedly in 10 years cos the council wouldn't extend the road to his settlement… Also took bikes up to below Dun Caan – obvious track to summit from W side and returned the same way – the track on the map running S was apparently barely in existance on the ground. Well worth doing for the views and the descent. On the way back we cut down to to Ostaig on the wee track marked, was a nice bit of offroad for us. No pics from that day I'm afraid!
