As an AI, I don't have personal preferences, but I can provide information. Urban hiking can be attractive to many people as it offers the opportunity to explore a city's unique architecture, parks, and neighborhoods while getting exercise. It can also provide a different perspective of a city and allow for discovery of hidden gems and local culture. Additionally, urban hiking can be a convenient way to stay active for those who live in cities and may not have easy access to traditional hiking trails. **

You can find urban exploration groups by searching online on social media platforms like Facebook or Meetup. Look for groups that are specifically dedicated to urban exploration in your area.

Some popular urban exploration sites in Hamburg include the old Elbe Tunnel, which was built in 1911 and is now open to pedestrians and cyclists, offering a unique underground experience.

I would recommend Vancouver, Canada as a travel destination that offers a good balance between urban life and natural beauty. The city is surrounded by stunning mountains and the Pacific Ocean, providing plenty of opportunities for outdoor activities such as hiking, skiing, and kayaking, while also offering a vibrant urban experience with its diverse neighborhoods, cultural attractions, and delicious food scene. Another great option is Cape Town, South Africa, which boasts a beautiful coastline, iconic mountains, and lush vineyards, while also offering a bustling city with a rich history, vibrant arts scene, and diverse culinary experiences. Lastly, I would suggest visiting Portland, Oregon, which is known for its proximity to the stunning Columbia River Gorge and the Oregon Coast, as well as its hip urban vibe with a thriving food and craft beer scene, eclectic neighborhoods, and a strong emphasis on sustainability and outdoor recreation. **

The United Kingdom is still technically united, as it consists of four constituent countries: England, Scotland, Wales, and Northern Ireland. However, there have been growing tensions and calls for independence in Scotland and Northern Ireland in recent years. The Brexit vote also highlighted divisions within the UK, with Scotland and Northern Ireland voting to remain in the EU while England and Wales voted to leave. The issue of unity within the UK remains a topic of debate and concern. **

Urban design is more closely related to city planning than urban development. City planning focuses on the organization and development of urban areas, including land use, infrastructure, and public spaces, which are all key components of urban design. Urban development, on the other hand, typically refers to the physical construction and economic growth within urban areas, which is influenced by urban design and city planning decisions. Therefore, while urban design is related to both city planning and urban development, it is more aligned with the principles and goals of city planning. **
