They’re on to the next adventure! And it’s really, really high up.

Barton Brooks and his partner, Gregg, planned a surprise trip to take his mother Carla on 20 outings in Europe’s biggest cities, after her husband, Karl, died last year. The group arrived in beautiful Switzerland this week, stopping in Gruyères to sample delicious cheeses and visit old castles. With suggestions from PEOPLE readers, Carla, Barton and Gregg took a train ride through the Swiss countryside, visited the snowy Jungfraujoch peak and visited the famous lake-town, Lucerne. “It is gorgeous!” Carla tells PEOPLE of Switzerland.

A bout of altitude illness landed Carla in a Lucerne hospital for a few days, but she’s rested, recovered and ready for her next adventure! Leave suggestions for Carla, Barton and Gregg in the comments section below, they haven’t decided on their next European city and would love some guidance. We’ll post a new episode of “Carla’s Comeback” every Wednesday, so be sure to follow all 20 of their adventures here!
