I will be Stockholm for 4 days prior to a work trip and would like to be active during my few days off. I am considering doing active day trips from Stockholm a kayak trip in the archipelago, day hike in Sormlandsleden and maybe mountain bike. OR... would it make more sense to stay out of Stockholm for a few days and try and put together some hike/kayak options elsewhere? I had hoped to do some mountain hiking but as I research, I understand that the nearest mountain hiking area is 5 hours + away. Any suggestions for some different activities for an active vacation would be appreciated... hiking, kayaking and biking seem to be the activities I can find so far. Thanks!
