What you can book
GetYourGuide lists Shiobara under Nasushiobara. The choices are a private day tour of the gorge and its bridges ending with an outdoor bath, a seasonal coach tour that pairs the Momijidani bridge with Nasu’s Sessho-seki and a foot bath, and two-day tours combining Nasu and Shiobara with an onsen hotel.
In Nasushiobara city itself — around the shinkansen station, not in the onsen valley — there are a guided bar-hopping evening and a sushi-making class.
This is thin coverage, and most products are new with few reviews. Shiobara is straightforward to visit on your own by JR bus.
