I can only agree with Mattia: it's a short stretch of road through fields, but otherwise completely unspectacular, not even worth a tip...

Biederthal is often reached by car from Basel / the Birstal valley, but this point here is nothing special in itself.

climbed up all the way to Ramel ridge

A sign has now been posted: "No drinking water."

The current parish church of Oltingue was built between 1827 and 1831 in late classicist style. Striking features include the triangular pediment above the round-arched portal and the Callinet organ from 1843, which is still in use. Together with the presbytery and the former school, the church forms a well-preserved village ensemble from the Louis-Philippe period. The church replaced an older mother church outside the village.

@Koblinator regarding main roads: yes, but it must be made very clear that the French 1. consider and respect cyclists more than the Swiss (in my experience) and 2. therefore always drive very generously around them (changing lanes to the left). After 17 years of racing, constantly on the Swiss-French border, my clear conclusion is...F = Tour de France country...

The exit from Mariastein takes place in a beautiful rural setting, among wheat fields and on a perfectly surfaced road.

A nice road offering with a few small bumps but nothing to impact ones speed. Enjoy the beautiful Alsatian scenery and architecture along the way.
