WASSERFALLEN REGION
This is a great getaway both in the summer and winter. Depending on where you live in Basel, it is a only a 30-40 minute car ride away. A cable car from Reigoldswil can take you to the top of Wasserfallen or you can choose to hike up. It's about a 2 hour hike. On the top there are play areas for kids, zip lining and other other outdoor fun. There is also a restaurant on the top. On your way down, you can even rent scooters and zip down the curvy mountain lanes if you like some more excitement. www.region-wasserfallen.ch/en/
AUGUSTA RAURICA
Just a short car ride away, the Augusta Raurica can be a great day out for the family if you want to walk around and explore some ancient Roman ruins. It has the best preserved ancient theatre north of the Alps among various other roman sights. The annual festival here is a great time to visit because it is when history comes alive with gladiators, chariot rides, ancient Roman games and food. Because of Covid, the festival has been put on hold the last two years, but good to keep in mind and look out for in the future. www.augustaraurica.ch/en
LAKE LUCERNE LIDO
Lake Lucerne is a great place to head to when you are looking for some vibes amidst the Swiss mountains.

COLMAR
One of the best things about being in Basel is how easily one can hop across the border to France and Germany just for a day. Colmar is a lovely little French town in the Alsace wine region. The town looks right out of a fairy tale and a great place to wander through its cobbled streets and soak in all the pretty homes and stores. If you plan well, you could combine it with some wine tasting along the way. The Colmar Christmas market in December is definitely worth a visit. www.tourisme-colmar.com/en/visit/presentation/discover
