Preparing for Your Klet' Mountain Hike

Before you set off, you need to prepare for a steady uphill climb. The elevation gain is about 500 meters from the city center. While the paths are safe, they can be rocky and steep in certain sections. Wear sturdy walking shoes or hiking boots to protect your ankles. Check the weather forecast before leaving, as the summit is often much cooler than the town.

You should also download a digital map or carry a physical one. Having a trail map from Český Krumlov to Kleť ensures you stay on the right path. Many hikers get confused at the initial junctions near the station. Carry enough water, as there are no shops along the forested trail until you reach the summit restaurant.

• Checklist:
• Sturdy hiking boots or sneakers.
• At least 1.5 liters of water.
• A lightweight rain jacket.
• Cash in Czech Koruna for the summit hut.
• Fully charged phone with offline maps.

How to Hike to Klet' Mountain Summit Step-by-Step

The journey to the top is straightforward if you follow the color-coded trail system. The green trail is the most popular choice for travelers starting directly from the city. It offers a mix of deep forest shade and occasional clearings. Follow these steps to reach the summit safely.

1. Locate the Trailhead: Walk to the main Český Krumlov train station north of the old town. Look for the green hiking markers on the wooden poles behind the station building. (Time: 10 mins | Cost: $0 | Location: Train Station | Mistake: Walking toward the bus station instead).
2. Follow the Green Markers: Enter the forest and keep a close eye on the green and white stripes painted on trees. The path begins with a gentle slope but soon becomes steeper. (Time: 60 mins | Cost: $0 | Location: Forest Trail | Mistake: Following unmarked mountain bike tracks).
3. Navigate the Steep Ascent: The middle section of the trail is the most demanding part of the hike. Take short breaks and stay on the main path to avoid erosion. (Time: 40 mins | Cost: $0 | Location: Middle Slope | Mistake: Rushing and burning out before the final stretch).
4. Reach the Josef Tower: As the trees thin out, you will see the stone tower and the television transmitter. This is the official summit of Kleť. (Time: 20 mins | Cost: $2-5 for tower entry | Location: Summit | Mistake: Arriving after the tower closes in the late afternoon).

Choosing Your Trail: Green vs. Yellow Paths

Deciding which path to take depends on your time and energy levels. The green trail is the fastest way to the summit from the city. It is approximately 5.5 kilometers long and very direct. However, it is also the steepest option, which might be tough for small children or inexperienced hikers.

The yellow trail is a great alternative if you want a longer, more gradual walk. It winds through different parts of the Blanský les protected area. You might also want to read a chairlift vs hiking comparison to see if a one-way trip is better for you. Many visitors choose to hike up the green trail and take the chairlift down to Krasetín to save their knees.

What to Expect at the Klet' Summit in 2026

Once you arrive, you are rewarded with several attractions. The Josef Tower is the oldest stone lookout tower in Bohemia, built in 1825. For a small fee, you can climb to the top for a 360-degree view. On clear days, the jagged peaks of the Austrian Alps are visible on the horizon. This is a highlight for anyone visiting the Czech Republic.

Next to the tower is a mountain hut serving traditional Czech food. You can enjoy a hot soup or a cold beer after your climb. The summit also hosts the Kleť Observatory, which is famous for discovering asteroids. Check the official tourism portal for specific opening hours in 2026. The atmosphere at the top is friendly and relaxed, making it the perfect spot for a long lunch.

Troubleshooting and Common Hiking Problems

Even well-prepared hikers can run into issues on Kleť. The most common problem is losing the trail markers in the denser parts of the woods. If you haven't seen a green stripe for more than five minutes, turn back to the last one you saw. In winter or early spring, the paths can be very icy, requiring traction cleats for safety.

• Common Problems:
• Missing the last chairlift down (usually around 5:00 PM).
• Running out of water on hot summer days.
• Restaurant only accepting cash or local cards.
• Sudden afternoon thunderstorms in July and August.
• Phone GPS failing under heavy tree cover.
• Taking the wrong turn at the Blue/Green trail intersection.
