A proper extended weekend: one Supercharger hop to reach the Alsace mountains, then three-plus days on a genuinely famous 77km ridge road, glacial lakes, farm-inn munster, and the GR5 underfoot.
This is a different Lac Blanc from the famous one above Chamonix — this one sits at 1050m in the Alsatian Vosges near Orbey, a glacial cirque lake ringed by cliffs and spruce forest, right on the Route des Crêtes. That road is the real draw: 77km of pure ridgeline driving (or riding) from Col du Bonhomme to the Grand Ballon, crossing the Col de la Schlucht, the Hohneck and the Markstein, with the Alsace plain dropping away on one side and the Lorraine valleys on the other. Farm-inns (fermes-auberges) along the way serve munster made a few kilometres from where the cows grazed. It's far enough from Meudon to need real charging planning, which is exactly why it's an extended-weekend trip rather than a standard one.
Real driving distance Meudon-la-Forêt → Lac Blanc (Orbey) is about 463km, roughly 4h55 of pure driving time via the A4 then A33/A31 towards Nancy and on through the Vosges foothills (Rome2Rio road-distance figure). On a 97%-SOH Model Y Premium with a realistic ~330–370 km real-world range, that's one mandatory charging stop, not two — the remaining ~163km after Nancy is comfortably within range even before the mountain climb.

What you can do at Lac Blanc: walk the lake loop trail (Tour du Lac Blanc), or head to Lac Blanc Parc d'Aventures, a treetop adventure course right by the lake — 2025 rates: Parcours Oursons (ages 3–6) €13, Pack Exploration junior (6–15) €16 / adult (16+) €21, Pack Challenge junior €21 / adult €26. Open May–September.

One Supercharger stop at Nancy breaks the drive into manageable legs — figure a real travel day of 5.5–6.5 hours with charging and a lunch break; add an optional second stop at Saint-Dié-des-Vosges if you want more buffer before the climb. Arrive at Orbey/Lac Blanc by mid-to-late afternoon, set up camp, and take an easy evening walk around the lake loop.

Drive (or ride, if you're up for real climbing) the Route des Crêtes south from Col du Bonhomme through the Col de la Schlucht toward the Hohneck (1363m) — park and take the short walk to its rounded summit for a 360° view over the Vosgian valleys and the Alsace plain, with the Black Forest and sometimes the Alps visible on clear days. Stop for lunch at a ferme-auberge along the way for the classic marcaire menu (soup, roigabrageldi potatoes, smoked meat, farmhouse cheese, bilberry tart) — tarte aux myrtilles alone runs about €3.80–7 depending on the farm, munster fermier itself around €15.80/500g if you want to bring some home.

Push on to the Grand Ballon, the highest point of the Vosges at 1424m, recognisable from far off by its white radar dome. Alternatively, spend a lower-key day at Lac Blanc itself — the lake loop walk plus the treetop adventure park (see prices above) — and save your legs for a longer hike.
Same charging plan reversed — one mandatory stop at Nancy, plus the optional Saint-Dié-des-Vosges buffer if you want it. Leave enough time for the stop(s) plus a lunch break — treat it as a full travel day.
Bike loaded inside per the Car Camping & Bike Guide — no range penalty on the drive down, which matters over 460km. Once there, the Route des Crêtes and surrounding forest roads offer real elevation and genuine Vosges VTT terrain; this is a trip where the climbing legs get a workout, so pace it against the hiking and driving days.
