The Black Forest is where a sensible plan to “make decent progress” goes to have a lie-down. One minute you are threading through fir trees behind a lorry doing 38mph, the next you are on a perfect ribbon of tarmac, windows down, grinning like an idiot at a view that appears out of nowhere. For a European road-trip crew, it is a proper reward for getting off the motorway – and a very good place to find out whether your trusty rusty wreck has a working cooling system.

This is not a place to attack with a stopwatch, nor a region to dismiss as a quick detour on the way to somewhere else. The Black Forest rewards curiosity, a little patience and the occasional questionable decision involving cake the size of a spare wheel. Get the route right and it delivers forests, valleys, lakes, big mountain scenery and towns that look suspiciously pleased with their supply of cuckoo clocks.

Why the Black Forest belongs on a rally route

South-west Germany has the sort of roads banger rally teams talk about over a late beer: varied, scenic and entertaining without demanding that everybody pretend to be a racing driver. The forest itself stretches across a huge area near France and Switzerland, so you can shape it around a wider European run rather than treating it as a destination with only one way in and out.

That flexibility is its real trick. Coming from the north, it makes a brilliant bridge between the Rhine, Stuttgart and the Alps. From the west, it fits neatly after a French leg. Heading south, it gives you a cracking route towards Switzerland, Lake Constance or northern Italy. You can make it a full day of driving, or spend two nights and properly enjoy it. The latter is better if the itinerary allows, especially when your car has developed a new noise that needs investigating at a sensible pace.

The roads are generally well surfaced and clearly signed, but this is still mountain driving. Expect bends, changing weather, cyclists, motorbikes and local traffic that knows every corner far better than you do. A road book can point you towards the good stuff; common sense is still in charge of the steering wheel.

The Black Forest driving roads to remember

The Schwarzwaldhochstrasse, known as the Black Forest High Road, is the famous name on most drivers’ lists. It runs between Baden-Baden and Freudenstadt, taking in high viewpoints, woodland and enough sweeping bends to make even the most reluctant co-driver look up from their phone. It is popular for a reason, which also means it can be busy in peak summer and at weekends. Start early if you want the open-road feeling rather than a moving car park of enthusiastic motorcyclists.

For more drama, work the B500 into a route with the Mummelsee area and the slopes around Ruhestein. The lake itself is an easy stop, although “quick photo” may become “coffee, cake and an argument about whether we can fit a cuckoo clock in the boot”. Views on clear days stretch a very long way, but low cloud is part of the deal. If the weather shuts in, the forest can feel wonderfully moody. If your main aim is huge panoramas, it depends entirely on the forecast.

Further south, the roads around Titisee, Schluchsee and Feldberg provide a more leisurely combination of lakeside cruising, climbs and places to stop without treating every mile as a stage of the Monte Carlo Rally. Feldberg is the highest point in the region and brings a more alpine flavour, particularly as you get closer to the Swiss border. It is a fine choice for teams continuing south, but do not underestimate the time: narrow roads, photo stops and one team needing a bonnet-up moment can turn a short distance into a full afternoon.

The B31 through the Höllental, or Hell Valley, is another memorable stretch. The name sounds more dramatic than the drive itself, but the gorge, steep hillsides and changing landscape give it plenty of character. It is more of a useful scenic connector than a road to repeatedly lap while shouting encouragement at a 20-year-old hatchback. That is probably for the best.

Choose character over mileage

The temptation is to stitch every famous road into one heroic day. Resist it. A 150-mile Black Forest route can take far longer than the same distance on French autoroutes, and that is precisely the point. Leave room for delays, viewpoints, fuel stops and the inevitable convoy split when somebody follows a sat-nav shortcut down a lane intended for goats.

One excellent mountain road is more memorable than five rushed ones. Pick a high route, a valley route and a proper overnight stop, then allow the day to unfold. It is adventure meets bonkers, not an endurance test in a damp car park.

Towns, lakes and stops that earn their place

Baden-Baden makes a smart northern gateway if your route allows it. It feels polished compared with the muddy-tyre, sticker-covered spirit of a banger rally, but its old streets, spa-town setting and access to the High Road make it useful. You do not need to spend all day there. It is a good place to refuel people and vehicles before the climbing begins.

Freudenstadt is practical for an overnight, with a broad central square and enough facilities to regroup a scattered convoy. It is less about ticking off attractions and more about ending a proper driving day somewhere civilised, where dinner is not a packet of crisps found under a passenger seat.

Triberg is the obvious cuckoo-clock-and-waterfall stop. Yes, it is touristy. Yes, it can be busy. It is still great fun if you embrace the silliness rather than trying to be above it. The waterfalls offer a leg stretch, the shops provide wildly impractical souvenirs, and the town has enough Black Forest character for the group photo your mates will actually share.

Titisee and Schluchsee are better choices when the weather is warm and you want the road trip to slow down for a bit. Park up, walk by the water and remember that not every rally memory needs to involve warning lights. In summer, lakeside stops can be glorious; in poor weather, they are less essential, so use the time for a longer driving loop or an earlier arrival at the hotel.

Practical bits before your rusty wreck heads for Germany

Germany is brilliantly easy to drive in when you are prepared, and mildly annoying when you are not. Carry the required safety kit for the countries on your route, including high-vis vests and a warning triangle where required. Check your headlights, tyres, brakes and coolant before you leave the UK, not at the first petrol station after a long ferry crossing while rain falls sideways.

The Black Forest’s climbs are not extreme by alpine standards, but old cars feel gradients, heat and heavy loads. If you are travelling in summer with four people, luggage, tools and a boot full of charity-rally nonsense, make sure the cooling system is genuinely healthy. Watch the temperature gauge on long ascents, use a lower gear when appropriate and let the car cool if it needs to. Bravado has never repaired a split hose.

Fuel is easy to find around larger towns but less predictable on the routes you actually came to enjoy. Do not wait until the needle is flirting with empty before looking for a filling station. Keep some euros or a suitable payment card handy, and remember that rural stations are not always set up for a large group arriving at once with twelve different card issues.

Parking needs a little thought too. Historic centres, popular lakes and viewpoints can be tight, especially for a convoy. Agree a meeting point rather than assuming everyone will squeeze into the same bay. If you are on an organised run such as Rusty Rex Rally, follow the day plan, attend the morning briefing and do not start with a wrong turn simply because somebody spotted a shortcut on a map.

When to go, and when to give it a miss

Late spring and early autumn are the sweet spots for many teams. The roads are usually quieter than high summer, temperatures are kinder to older cars and the scenery has plenty going on. Autumn colours through the forest can be ridiculous in the best way. Summer gives longer days and warmer lake stops, but brings holiday traffic, busy attractions and greater pressure on engines that already enjoy a bit of theatrical overheating.

Winter is a different proposition. Snow, ice and temporary road closures are possible at higher elevations, while daylight disappears early. It can be beautiful, but it is not the place for casual planning or questionable tyres. Unless your event is built for winter conditions and your car is properly equipped, save the high routes for another time.

The Black Forest works because it gives every team something slightly different. The keen driver gets the bends. The scenery hunter gets the viewpoints. The social crew gets lakes, cafés and an excuse to buy an enormous slice of gâteau. Give it enough time, keep your plans loose around the edges and let the best road of the day be the one you did not expect to find.
