No start point is pinned, so Maps begins at your phone's current location on the day. Google Maps takes at most 9 waypoints besides start and finish — 8 of 9 waypoints used. This line runs the AP-8 → A-15 via San Sebastián — the direct drive from Bidasoil Behobia.
Waze has no multi-stop link, so this route-in-one-go is Google Maps only — the Waze buttons below still navigate each leg.

The same stops on the N-121-A via Behobia, Endarlatsa, Bera and the Belate tunnel — pinned by the Doneztebe shaping waypoint (43.17218, −1.66974), 9 of 9 waypoints. A winding, slower drive through the Bidasoa gorge and over the Belate climb.
Belate/Almandoz tunnel night works can divert you over the old NA-1210 pass — check navarra.es or the tunnel signs on the day.
Wild boar and roe deer are a real risk in Navarra after dark — the Ultzama/Baztan valleys are boar country. If you take this line after dark, drop your speed and lead with the lights.
One dog on board. E10 petrol only — the car needs no 98, so never hunt for it. After the Spanish border it is one straight run: fill at Bidasoil Behobia (95 E5 — fine for the car), then no stop before Pamplona. Tap a stop to mark it done — state survives a phone lock.
Litres are derived, not measured: km × 6.5 L/100 km, each fill back to FULL, so you buy exactly what the leg burned. Fuel 1 sits 4.5 km earlier than the old stop, so it buys 0.3 L less at the cheap pump and AD Larose buys 0.3 L more — the total barely moves. Your own figure is 6.0–7.0 L/100 km; at 7.0 the 617.5 km leg still arrives with 6.8 L (97 km), and it only breaks at 8.10 L/100 km. 680 km is your usable-range line — every leg is under it.
The first fill moved to Gabriëls, Bisschoppenhoflaan 700/A (km 97.5) — its 24u/24 card pump is documented, and it comes 4.5 km earlier than the old stop, so the sequence still runs Gabriëls → Wancourt → … At 05:42 there is no shop, no toilet and no attendant, and pre-auth runs to €375: bring a second card. Maes Deurne (Waterbaan 114, km 102) is dropped — same detour class, 2.0 c/L dearer, no verified 24/7 hours.
Sunset on the Atlantic coast is ~19:00–19:10 CET, so Aire de l'Océan-Ouest is the last daylight stop. Bidasoil Behobia and the final leg to Pamplona are in the dark — take a headtorch or use phone light for the dog walk at Irun.
French school holidays 17 Oct – 2 Nov. 25 Oct is the middle weekend, so the heavy flow is the northbound return — your southbound direction is the light one. Expect company around Orléans and Bordeaux, not a jam. Bison Futé forecast not yet published; check 23–24 Oct.
The A86/A6b transit corridor you use is excluded from the Paris low-emission zone. The car restriction only runs Mon–Fri 08:00–20:00 and carries no sanctions before 2027. Sunday 25 Oct, corridor only: no sticker to buy, nothing to check.
Keep a physical card handy — phone-only wallets occasionally fail at the barrier. Do not enter télépéage (30 km/h) lanes.
