As with most things these days, there is an incredible amount of choice out there when it comes to choosing a yoga vacation. This might sound silly, but the first thing you need to think about is how much yoga is actually involved: some retreats offer classes once daily, others twice; some retreats are yoga only, others combine yoga with another activity.
Once you know how much yoga you want to do, work out where you want to do it – do you want to be up in the mountains, or down on the coast, and, importantly, how isolated do you want to be? Consider the style of yoga that you want to practice be it slow and steady, challenging and sweaty, or both, and finally, research it all again – you can never ask too many questions. The point of a yoga vacation is to leave you feeling even better than when you arrived, which is as personal a point as how you take your tea and toast.
