We ended up in Portsmouth for the evening, which definitely is not enough to explore the harbour area. We have added checkmark for visiting Stonehenge and it would not have sounded right if we just went back home. As always, some pictures below the post and one of the most eye catching things is the Spinnaker Tower, which we think is worth the visit as you would be able to see the entire harbour and Portsmouth from up there. However we left it for the next time due to getting dark and being rainy. Overall we enjoyed our evening by walking around, taking some pictures and getting some desserts in one of the cafes. Portsmouth Gunwharf Quays can offer many restaurants to choose from, some even with a view to ships and ferries coming in and out of the harbour, you may do some shopping in the area too.
