Assuming your trip will not be in Winter, one of the passes below will suit your needs:
Please check the above links for all information about what's included, how the passes work, prices, etc. As explained there, buying another pass will get you a discount on either of the above passes, plus a free Swiss Family Card so the children will travel for free.
