I find it safe to lock my bike in the market square. They are visible from the cafe windows and the entrance to the fish and chip shop. It gives a bit of peace of mind.

A convenient stop with easy access to toilets and great ice cream. It’s ideal for a quick refill, though be prepared for long queues at the counter. The paninis and sandwiches aren’t the best, but it serves its purpose.

Pleasant and enjoyable ride whilst taking in the sights. Early morning is best time to avoid pedestrians, walkers exercising around the lake and people walking their dogs.

The motorway right besides is quite noise, which disturbs the experience considerably. Also the part closer to the national bowl is a bit shabby. For the rest quite green pseudo-nature, but relaxing by bike.

An effort was made here to create a varied lake with a path around. It is quite nice, but as everywher ein the city the feeling of 'artificial' is quite strong.

A bit cumbersome with the bike and more intended for hikers - easier to stay on the path. But a nice idea to make the surrounding a bit more varied.
