If you want to go on an activity holiday, safety needs to be your top concern. You should spend plenty of time researching what you are going to do and making sure you will have the right instruction to do it safely and effectively. If you are at all unsure, don’t go ahead with the booking.
For something like a skiing holiday, you will need to book well in advance in order to secure the activities and accommodation you want. If you are interested in other activities whilst there, you can often book them along the way. Enquire when you arrive and ask at the hotel – they will often be able to advise you on reputable tour operators in the area.
Some activities will require specialist knowledge, so make sure you understand the physical requirements first. For example, a yoga retreat may not be suitable for someone who is new to the activity.
