Just beyond the ferry pier on Loch Katrine, this is a pleasing new place to stay, offering tent and motorhome pitches as well as cute camping pods with a little deck. They sleep two or four and come in two categories, one with underfloor heating and en suite bathroom. Book them well ahead. It's cheaper if you bring your own linen.
There's a two-night minimum stay for the en suite ones, one of which is adapted for wheelchair use.
