There aren’t any camping pods closer than Innerleithen/Glentress. There is a however campsite at the swimming pool.
There are of course a couple of hotels in the town, The Glen being the closest to the swimming pool and Rugby Club both used as race HQs for the MTB Marathon in previous years. Other Hotels include The Heatherlie, probably the next closest, and the County Hotel in the town centre. There is also the Phillipburn Hotel if you don’t mind paying for the luxury
As far as Self Catering goes Whitmuir Hall has a range of cottages, converted steadings etc.
