The Minibus Chase and Big Bus Chase are suitable for pregnant mothers, and we have had pregnant mothers join us on our chases before. Walking is minimal too on the chases, and we usually stay close to the car, so you may always rest in the car if you need to.
If you are pregnant, we generally do not recommend joining the Dogsledding and Snowmobile day trips as there is a risk of falling from both. It would be best if you could check with your doctor for medical advice beforehand if you are unsure.
