Getting to the Diana Observation Tower

Reaching the summit is part of the adventure. Most visitors take the historic funicular railway. The station is tucked away in an alley near the famous Grandhotel Pupp. You can easily find it while exploring the best things to do in Karlovy Vary. The funicular runs every 15 minutes and takes you up the steep lush hillside.

Tickets are affordable and can be purchased at the base station. In 2026, expect to pay around 150 CZK for a return trip. You can check the latest schedules via the Dopravní podnik Karlovy Vary website. The ride is smooth and offers a quick glimpse of the spa woods. It is a great way to save energy for the walks at the top.

If you enjoy physical activity, several hiking trails lead to the tower. These paths are well-marked and wind through beautiful beech forests. The walk from the town center takes about 30 to 45 minutes. It is a steep climb but very rewarding for nature lovers. Many people choose to take the funicular up and walk back down to the Grandhotel Pupp for afternoon tea.

The View from Diana Observation Tower

The Diana Observation Tower has stood since 1914. It is a sturdy brick structure that rises above the tree line. The best part about the tower is that entry is completely free. You do not need a separate ticket to climb to the top. This makes it one of the best value attractions in the city.

You can choose to climb the 150 steps to the observation deck. If you are tired, a modern elevator is also available inside. The elevator is free and fits about eight people at a time. Once you reach the top, the 360-degree views are breathtaking. You can see the entire spa district and the surrounding Ore Mountains. You can find more details on the Karlovy Vary Official Tourism portal.

The tower deck is open year-round, though it can be windy. On clear days, you can see for miles across the Bohemian landscape. It is the perfect spot to orient yourself before visiting other landmarks. You will see the river winding through the valley below. The red roofs of the historic buildings look like a miniature model from this height.

Exploring the Papilonia Butterfly House

The Butterfly House, known as Papilonia, is located right next to the tower. It is an indoor tropical garden kept at a constant 30 degrees Celsius. This is a separate attraction that requires a paid ticket. When visiting Diana Observation Tower and Butterfly House, this is often the highlight for children. The space is filled with hundreds of exotic butterflies from around the world.

• Pros: Up-close interaction with rare species, great photo opportunities, and a perfect rainy-day activity.
• Cons: The humidity can be intense, the space is relatively small, and it gets crowded on weekends.

Inside, you will find butterflies with wingspans larger than your hand. They often land on visitors, especially if you wear bright colors. The garden is designed with tropical plants and small water features. It feels like stepping into a different continent for a brief moment. Be sure to keep your camera lens clean, as the humidity will fog it up instantly.

The staff provides information about the life cycle of these insects. You can even see the nursery where new butterflies emerge from their cocoons. It is an educational experience that lasts about 30 to 45 minutes. Most visitors find the entry fee worth it for the unique atmosphere. It is a stark contrast to the cool forest air outside.

Dining and Hiking Near the Tower

After your visit, you can relax at the Diana Restaurant. It features a large outdoor terrace with plenty of seating. The menu focuses on traditional Czech cuisine and local beer. It is a convenient spot for lunch, though prices are slightly higher than in the town center. The atmosphere is casual and very welcoming to families.

Nearby, there is a small mini-zoo that kids will love. It usually houses goats, ponies, and pigs that you can observe for free. This area makes the hilltop feel like a complete resort destination. You could easily spend half a day here without getting bored. It is a great break from the formal atmosphere of the karlovy-vary-colonnades-walking-route.

Several trails branch out from the Diana complex. One popular path leads to the "Deer Leap" statue. This is a famous bronze chamois perched on a rock. The forest paths are wide and mostly flat once you are on the ridge. These trails are perfect for a gentle afternoon stroll. You will find many benches where you can sit and enjoy the silence of the woods.

Practical Tips for Your 2026 Visit

To make the most of your trip, arrive early in the morning. The funicular starts running at 9:00 AM. By midday, the lines for the train can be quite long. If you visit in 2026, consider buying a combined ticket for the funicular and the Butterfly House. This often saves you a small amount of money and time. You can find travel updates on the Visit Czechia website.

Wear layers of clothing when you visit. The Butterfly House is very hot, but the tower top can be chilly. Having a light jacket you can remove is essential for comfort. Most areas at the Diana complex accept credit cards. However, having some small Czech Koruna coins is helpful for the public restrooms. The staff generally speaks basic English and German.

Best for: Families with children, couples looking for views, and nature photographers.

Skip if: You have severe claustrophobia (for the butterfly house) or very limited time in the city.

Alternative: If the tower is too busy, try the Jan Becher Museum for a different indoor experience.

Final Verdict on Visiting Diana Observation Tower and Butterfly House

Verdict: Visiting Diana Observation Tower and Butterfly House is a top-tier Karlovy Vary experience. The combination of free views and the magical butterfly garden is hard to beat. It offers a perfect escape from the busy spa colonnades. While the Butterfly House is small, the overall value of the hilltop complex is high. We highly recommend it for any first-time visitor to the city.

The funicular ride adds a sense of nostalgia to the journey. The tower provides the best perspective of the town's unique geography. Even if you skip the butterflies, the tower and the forest walks are worth the trip. It is a peaceful way to see the natural side of Bohemia. Make sure to grab some official spa wafers before you head up for a snack at the top.
