As the previous editions of the annual race have shown, spectators line up and cheer the cyclists almost everywhere along the route, so the “best” spot depends pretty much on where you live in relation to the Swiss route.
Cyclists will arrive from Dole (France) to Lausanne through the Bois d’Amont, La Vallée de Joux, the Col du Mollendruz, Cossonay, and Préverenges.
The start is scheduled for 1:20 p.m. and Lausanne should be reached four hours later, around 5:20 p.m.
For the next stage on July 10th, racers will depart from Aigle at 12:45 pm and cycle toward Vionnaz, Cully, Châtel-St-Denis, Bulle, Les Moulins, Les Mosses, Col de La Croix, and Morzine before crossing back into France.

These are some of the good viewing / cheering spots along the route:
In the Vallée de Joux, you can watch the cyclists whizz by in the villages of Le Brassus, Le Sentier, Le Lieu, Le Séchey, Les Charbonnières, and Le Pont.

You can watch the competitors race by virtually anywhere along the nine-kilometre path — they will arrive from the La Vallée de Joux from the south, climbing up the Avenue d’Ouchy, then cross Place Saint-François and Pont Chauderon, then on to the Avenue de Beaulieu, and finishing in front of the Pontaise Olympic stadium.
All these streets will provide good viewing opportunity.
The first mountain stage will start on the Place du Marché in Aigle, where you can watch cyclists pass by as they climb toward mountain villages (see above), all of which provide good viewing for spectators.

Unless you actually live in the vicinity of the route, keep in mind that you can’t access it by car as all the roads be closed to traffic and you will have to park elsewhere.
If you are watching from any of the above mentioned mountain locations (Vionnaz, Cully, Châtel-St-Denis, Bulle, Les Moulins, Les Mosses, Col de La Croix, and Morzine), taking a bus up from Aigle is probably the smartest choice.
Additionally, on Saturday from noon, the Lausanne-Sud motorway, as well as the UNIL-EPFL, Malley and Maladière entrances and exits will be closed to traffic until 6 pm.
However, the A1 / A9 / A12 motorways will remain open in Vaud, Fribourg and Valais.
You can access the route(s) by public transport, which will be “reinforced” during La Tour de France.
For instance, in the Lausanne, the metro will run more frequently, and a temporary line, will link La Riponne to Oiseaux, making it easier to access the last kilometre of the route. More trains will also circulate on the two days as well, especially regional Vaud trains as well as the RegioExpress Genève – St-Maurice.
