Hi,
I have seen mention of Bivvy/Bivouac as an alternative to camping on the GR20.
Please could someone describe if they mean camping without a tent?
I would like to keep the weight down by not carrying a tent (late June). But I get the impression this is risky since you can not guarantee a spot in the refugio (although perhaps it changes this year with mandatory bookings?). Also it is nice not to have to rush the day just to secure a bed in a refugio.
thanks for the advice
