IF you want short flat rides and walking you can do together, the lakes around Torrevieja are nice.
Much as I like riding my bike around Torrevieja there’s no way I’d recommend it to anyone looking for holiday with a “biking holiday destination”!
tbh, this line stood out:
“I’ve a non-biking partner (she prefers hiking and beaches):”
I wouldn’t recommend it for a biking holiday either ;)
*I was thinking more of a road trip along the coast.
