May and September. May is the sunniest month of the year at Aviemore by a wide margin, 181 hours of sunshine against 143 in June and July, with sixteen and a half hours of light, the firmest ground of the year, the free water at Ballindalloch back on from the first of the month and the midges barely started. September is its mirror: midges fading, the summer crowds gone, the salmon season running to the 30th, the first autumn colour in the birch woods and still nearly thirteen hours of light. June is close behind for anyone sleeping indoors, because it has the longest light of the year, and April is the driest month inland with no biting insects at all.
This is a sheltered river valley on old railway, forest track and riverside path rather than a mountain route, and it is walkable in far more of the year than most Scottish long-distance trails. The main line has no ferry, no tidal section and no high crossing, and the managing authorities' own answer on timing is that you can walk it at any time of year, with short daylight and boggy ground the winter problems rather than snow. What changes through the year is service rather than access: the free water at Ballindalloch runs May to the end of September, distillery visitor centres shorten their week through the winter and pause at Christmas and New Year, the packaged tour season runs 1 March to 24 October, and the two ends behave differently, with Aviemore trading hard all year on the back of the ski season while the Moray coast end is quiet and its visitor attractions run to a season. Two biting seasons overlap here and they are not the same one. Ticks run roughly March to October on this ground, which the Cairngorms park authority says milder winters have been stretching, and the ground here suits them in a way a west-coast hill route does not, since the line spends its length in long grass, bracken-edged forest track and river meadow with deer and cattle: one through-walker's account of the whole trail describes picking multiple ticks off daily on the overgrown sections, so build in a proper check at the end of the day rather than treating it as a west-coast problem. Midges are the other, and they are what will spoil a summer night rather than a summer day. The reason is wind: the valley averages under 6 knots from May to September, which is below the speed at which midges stop flying, while the coast at 8 to 10 knots usually is not. One rule catches campers out and it runs through the whole good half of the year: between 1 April and 30 September fires and barbecues are banned across the Cairngorms National Park under a byelaw, with a fine of up to 500 pounds, and the park authority names a camping stove as the alternative. Our line crosses into the park near Mains of Dalvey, between Ballindalloch and Cromdale, so roughly the southern half of the walk is inside it, including the free camping ground at Ballindalloch Station and everything south of it.
Month-by-month guide
January
Poor
The wettest month of the year inland and only about seven hours between sunrise and sunset, against official sections of 13 miles. Nothing prevents the walk, but two or three days of a six to eight day plan have to be shortened or begun in the dark.
5.3 in the valley (Aviemore), 6.9 on the coast (Lossiemouth)°C high · -0.6 in the valley, 0.6 on the coast°C low · about 7h20m mid-month, sunrise to sunsetWatch for: Rain, and what it does to the one hard section. The trail's own description of Ballindalloch to Grantown-on-Spey warns that its two stepping-stone burns may be difficult to cross in flood conditions, and January is the month most likely to produce those conditions.
February
Mixed
The best of the three deep winter months. Daylight is back to nine and a half hours, rainfall inland has dropped by a quarter from January, and the salmon season opens on 11 February, which puts people back on the riverbank and life back into the fishing hotels.
6.0 in the valley, 7.6 on the coast°C high · -0.6 in the valley, 0.8 on the coast°C low · about 9h25m mid-monthWatch for: Anglers on the bank from the 11th. Much of the middle of the route runs along working beats, so step round a pool somebody is fishing rather than through it.
March
Mixed
The service year restarts in March: Cardhu goes back to daily opening, the Strathspey heritage railway begins its standard season, and the self-guided tour operator's itineraries run from 1 March. The coast has its driest month. Ground is what holds the month back.
8.2 in the valley, 9.3 on the coast°C high · 0.5 in the valley, 2.0 on the coast°C low · about 11h40m mid-monthWatch for: Ticks. The Cairngorms park authority puts the old season at roughly March to October and says milder winters have stretched it, and this route runs through woodland, long grass and river meadow for most of its length.
April
Good
The driest month of the year inland and a real jump in sunshine, 142 hours at Aviemore against 36 in January. Fourteen hours of light covers a 13 mile section without hurrying, the ground is drying and the midges have not started.
11.4 in the valley, 11.7 on the coast°C high · 2.1 in the valley, 3.9 on the coast°C low · about 14h15m mid-monthWatch for: Ground-nesting birds at Insh Marshes, between Kincraig and Kingussie on the last section, where the reserve asks for dogs on a short lead from 1 April to 15 August. The path through Ben Aigan forest between Fochabers and Craigellachie has also been shut for a weekend in late April in each of the last three years for a mountain bike event, so read the managing authorities' route news before that weekend. The first of April is also the day the Cairngorms fire and barbecue byelaw comes into force for the summer, so from here to the end of September a stove is the only legal way to cook in the southern half of the route.
May
Excellent
The sunniest month of the year at Aviemore by a wide margin, 181 hours against 143 in June and July, with sixteen and a half hours of light, firm ground and only the first midges. Everything that runs to a season is running by now.
14.6 in the valley, 14.1 on the coast°C high · 4.4 in the valley, 6.2 on the coast°C low · about 16h30m mid-monthWatch for: The first midges, usually late in the month. Early May is normally clear; the last week is not reliably so.
June
Good
The longest light of the year, so a 13 mile section can start late and still finish in daylight, and the last month before the school holidays load Strathspey. Midges are the only reason this is not the best month.
16.7 in the valley, 16.3 on the coast°C high · 7.6 in the valley, 9.1 on the coast°C low · about 17h55m mid-month, and 18 to 19 hours at the solstice by the managing authorities' own figureWatch for: Midges get serious around the middle of June. They bite hardest in still air just before dawn and around sunset, they are not put off by rain or darkness, and they stay close to the ground near their breeding sites, which describes a wooded riverside embankment exactly. Ticks are at their most active now, in the woodland and long grass this route runs through.
July
Good
The warmest month and one of the drier ones, with light long enough for any section on the route. What shapes a July trip is midges and Strathspey's holiday trade rather than the weather.
18.8 in the valley, 18.6 on the coast°C high · 9.5 in the valley, 10.9 on the coast°C low · about 17h25m mid-monthWatch for: Peak midges, morning and evening, worst on the wooded riverside between Craigellachie and Grantown-on-Spey. Wind is the only reliable relief and this valley has almost none of it, so the practical answers are to walk through the middle of the day, keep moving, eat indoors, and carry repellent and a head net if you are camping.
August
Good
Warm, still long in the light, and the heather is out on the open ground. Rain is climbing on both halves of the route, and the last weekend of the month is the worst time in the year to need a bed at the Strathspey end.
18.1 in the valley, 18.4 on the coast°C high · 9.2 in the valley, 10.7 on the coast°C low · about 15h20m mid-monthWatch for: Midges hold right through August and only start to ease in September. Ticks likewise.
September
Excellent
Midges fade, the school holiday crowds go with them, and there is still nearly thirteen hours of light, which covers any section on the route. The salmon season runs to the 30th and the first autumn colour arrives in the last week.
15.7 in the valley, 16.3 on the coast°C high · 7.2 in the valley, 8.9 on the coast°C low · about 12h55m mid-monthWatch for: Midges easing rather than gone in the first half of the month, and ticks still active.
October
Good
The best of the autumn colour set against the return of the rain, 100 mm at Aviemore against 60 in April. Ten and a half hours of daylight still covers a 13 mile section without a head torch, which is the last month you can say that.
11.6 in the valley, 12.9 on the coast°C high · 4.2 in the valley, 5.9 on the coast°C low · about 10h30m mid-monthWatch for: Rain. October is the wettest month of the year on the Moray coast and the second wettest inland, so the exposed first 8 km out of Buckie into a northerly can be a hard way to start a walk.
November
Mixed
Eight hours of light against official sections of 13 miles is the whole constraint, not the weather. The path is open, the towns are open, and a plan built on shorter days works perfectly well.
7.9 in the valley, 9.5 on the coast°C high · 1.4 in the valley, 3.0 on the coast°C low · about 8h05m mid-monthWatch for: Frost returning inland, nine nights of air frost at Aviemore against five on the coast, which is a real difference for anyone camping at the Strathspey end.
December
Poor
Daylight is most of the story. A 13 mile section is roughly four and a half hours of walking, so it fits inside six and three quarter hours of light with no margin for a late start, a long lunch or a wrong turn, and every day of a six to eight day plan is like that.
5.4 in the valley, 7.1 on the coast°C high · -0.9 in the valley, 0.5 on the coast°C low · about 6h40m mid-month, and 6 to 7 hours at the solstice by the managing authorities' own figureWatch for: The dark. Between October and March the managing authorities' own advice is to set out at first light and always check the time of sunset before you go, and December is the month that advice was written for.
