Travel in and out of the town will be seriously restricted. Bike or walk to get there and plan to get there about 2-3hrs before the rollout. The roadbook (when it’s available) will give full details of timings and the tourist info site for the town should have stuff on parking, spectator points, entry and exit routes. Towns really get behind it so they like to put on a bit of a show and it’s a matter of civic pride to be well organised and welcoming.
Start towns are normally fairly organised, there’s a set protocol of where riders are and need to be so they’re easy to get close to. Finish town is more chaotic, riders being whisked off for podium or anti-doping and more spread out.
Take some food and drink – everywhere selling anything will be busy and probably a bit of a rip off.
Also take suncream, umbrella and general comfort stuff – fold out chairs are always worth it!
We’ve done it a few times – went to Paris last year for the finish which was good fun. Did a day or so of general tourist city break then we got a seat in a cafe on the Champs early on the final day and just stayed there. Cost a fortune in food and drink! The general “cafe on the Champs” inflated prices plus TdF plus probably a Bloody British Tourist Tax, it was something like £6 for a coffee, £10 for a beer! 😳
Was worth it though for the atmosphere and the riders stopped right outside the cafe after the finishing sprint so we got some good pics. Got interviewed for French TV as well!
