Most of a good sled day happens the night before. This is the order we go in, from the pass to the join link, using the federations' pages for what they own and Aventerra for the rest.
Start with the pass and the trail status
In Quebec, the trail pass is not optional. The FCMQ states on its trail pass page that the droit d'accès is mandatory to use the snowmobile trails, and it is issued per snowmobile. For quads and dirt bikes, the FQCQ's trail pass page says the pass and its sticker are mandatory on the trail. Buy it before you plan anything else.
Aventerra draws the Quebec snowmobile, quad and dirt bike networks from MRNF, FCMQ and FQCQ data, so you can see the trails next to the terrain and the snow. Whether a given trail is open this morning is the federation's call, published on their own interactive map, which we check before we leave. The FCMQ's safety page adds the rules we repeat to every new rider: never ride alone, tell someone your route, and on frozen water stay inside the marked trail, where the ice has been checked.
Read the conditions for the day
Turn on the Snow Depth layer. Over Canada it is built from ECCC's HRDPS model and updated through the day as new runs publish, so it is the picture for today, not an average. Then tap the staging area and open the point forecast: current conditions, hourly and daily, with charts. The weather layers draw the wind, precipitation and clouds over the map, and one time scrubber moves them all to the hour you plan to be on the trail.
On Pro, weather along a route gives each point of the route the forecast for the hour you expect to pass it.
Snow depth is a model estimate, not a reading from a station, so we still look at the snow when we get there.
Build the route
Open the route builder and pick snowmobile. It starts near the area you are looking at, from your position or from a spot you tap, and builds routes on the phone over the trails around it. Set the length, the climb and the shape, a loop or an out and back, and add a place the route must pass if you have one in mind. Each result shows how much of it runs on trails. Where there is no routing coverage yet, the builder says so.
Save the route when you are happy, and ride it with turn cards. Free accounts keep three saved routes and Pro removes the limit.
Download the area
Open Offline Maps and frame the terrain you will ride. The app lists the layers and the estimated size before you confirm. The basemap with its places, snow depth, slope angle and cell signal come down together, with a routing pack for the area so the route keeps working with no signal. Add satellite, topo contours or the weather layers if you want them: every map layer downloads, and weather comes as the forecast published when you download. One offline region is free, and Pro removes the limit.
Do this at home on wifi. The app warns you when a download would run on cellular data and when the phone is short on space.
Share the plan with the group
Start a group activity and invite the crew by QR code or by join link. Add the stops so everyone sees the same day. Once you ride, positions arrive by internet or by mesh radio, whichever is reaching you, and the out-of-range alert tells you when someone falls behind by more than the distance set for the activity.
For the backcountry part of the day, the authorities are clear and we follow them. Avalanche Québec's page for snowmobilers asks every member of the group to take an avalanche course, to carry the rescue essentials in a pack on the body, and to read the Chic-Chocs bulletin before each outing. Avalanche Canada's sled resources say the same for the rest of the country. The app shows you the snow and the slope. The decision stays yours.
The trail layers, the routing profiles and the route builder are described on the Trails and routing page, with where the data comes from.
