Stockholm Adventures offers guided and self-guided tours in and around Stockholm. Visit Stockholm lists sailing, kayaking, wildlife safaris and bicycle tours among its summer activities, and skating on natural ice in winter. Tours are offered year-round, according to both the company and Visit Stockholm.

For autumn and winter, the company lists a four-hour kayak tour called Stockholm Winter City Nobel Lights. It costs SEK 1,445 (about $136, or £107) and is for people aged 15 and over. The company describes the water as cold but not frozen, with quiet waterways and ice skaters nearby. Its other year-round options include bike tours, archipelago boat trips and hikes on Stockholm nature trails. Visit Stockholm says guests can book a scheduled tour or arrange a private one.

The company says it puts emphasis on equipment, food and hospitality. A reviewer quoted on its website said a small-group tour was more physically demanding than expected; another described doing a self-guided hike alone in the rain. The listed four-hour duration and age limit apply to the Nobel Lights kayak tour, not necessarily to the other activities. The website does not give a general visit length, so check the details for the tour you choose.
