If you have 7 days to spend in Kidderminster, there are several things you can do:
The Severn Valley Railway is a heritage railway that runs between Kidderminster and Bridgnorth. It takes about an hour to travel each way, and there are several stops along the route where you can explore local towns and villages. A round trip would take about 5-6 hours.
The Wyre Forest is a large forested area that offers hiking trails, cycling routes, and opportunities for wildlife spotting. You could easily spend a full day exploring the forest.
The West Midlands Safari Park is located just outside Kidderminster and is home to a variety of animals, including lions, tigers, elephants, and giraffes. There's also a theme park on site with rides and attractions. A trip to the West Midlands Safari Park would take a full day.
The Museum of Carpet is located in Kidderminster and explores the town's history as a centre for carpet production. It's a small museum, so you could easily visit in an afternoon.
The Granary Hotel is a boutique hotel located in the Worcestershire countryside just outside of Kidderminster. It has a restaurant on site and is a great place to relax after a day of exploring.
