3. Explore Segontium Roman Fort

Just a short walk from the town centre, the remains of Segontium Roman Fort offer a glimpse into Caernarfon's ancient past. Established around 77 AD, this fort was a significant military and administrative centre during the Roman occupation of North Wales. Visitors can walk among the foundation walls and envision the 1,000-strong regiment that once garrisoned here. The site provides excellent views over Caernarfon and towards Anglesey, and there is often a visitor centre with artifacts unearthed from the excavations.

4. Wander Cei Llechi (Slate Quay)

The revitalised Cei Llechi, or Slate Quay, is a vibrant area by Caernarfon Harbour, offering a blend of artisan shops, workshops, and eateries. This historic industrial hub has been transformed into a space where visitors can discover unique handcrafted goods, local produce, and art. Strolling along the quay provides opportunities to observe local craftspeople at work and enjoy the waterfront atmosphere, often with views of the castle. It's an excellent spot for finding distinctive souvenirs and experiencing a contemporary take on Welsh culture.

The Menai Strait, which borders Caernarfon, offers various water-based activities for nature lovers and adventure seekers. Options include leisurely boat tours to see the strait from a different perspective, or more active pursuits such as kayaking and paddleboarding. These activities provide a chance to appreciate the serene beauty of the coastline and observe local wildlife. Several local companies offer equipment hire or guided sessions for different skill levels.

Cost: Kayaking and paddleboarding sessions often start from around £40-£50 per person for half or full-day tours/rentals. Boat tours will have separate pricing.

Transport: Water activity providers are typically located near the waterfront or a short drive from the town centre. Plas Menai National Watersports Centre is a short distance from Caernarfon. Public transport or a taxi would be required for locations outside the immediate town centre, with taxi costs to Snowdonia areas (like Llanberis) ranging from £25-£30.
