If you're planning a day out in Cumbria, England's most northern-west county, you're in for a treat. Cumbria covers the Lake District, Eden Valley, the North Pennines, and a small part of the Yorkshire Dales. Here are some delightful activities to consider:

1. Conquer the Old Man of Coniston:
- Situated in the heart of the Lake District, the Old Man of Coniston is the highest point in traditional Cumbria. Choose from different walking routes, which can take up to 3 hours. The direct route starts from Coniston and offers amazing views of Lake Coniston once you reach the top. Be prepared for strenuous hiking, but the vistas are worth it! Best attempted in good weather due to strong winds and rain risks.

2. Explore Eden Valley and North Pennines:
- Eden Valley, flowing through Kirkby Stephen and Appleby, offers stunning beauty between the North Pennines and the Lake District. Enjoy riverside walks, sandstone cliffs, and picturesque landscapes. It's a professional walker's dream.

3. Visit South Lakes Zoo:
- Located in Barrow-in-Furness, South Lakes Zoo is a family-friendly day out. Get up close to endangered and rare animals, hand-feed giraffes, kangaroos, penguins, and lemurs. A smaller zoo, but cute and fun for all ages.

4. Discover Ambleside Roman Fort:
- Explore the Ambleside Roman Fort, tentatively identified as Galava. Learn about its history and enjoy the ruins. The fort overlooks Lake Windermere and offers a glimpse into ancient times.

5. Go Ape Whinlatter:
- Head to Go Ape Whinlatter for high ropes and Forest Segways. Enjoy views across Bassenthwaite Lake and Derwentwater. Located in Whinlatter Forest, it's an adventure-filled day in the great outdoors.

Remember, Cumbria's natural beauty, historic sites, and outdoor adventures promise an unforgettable day out!
