Bus stop ”Dalbobranten” then follow half arrows. Several possible bus departures, like for example bus 188 leaving Gullmarsplan at 18:02 (NB difficult to find bus 188 at Hållplatsläge/Läge/Hpl K in Gullmarsplan, so make extra time for walking about like a lunatic to get to "Arenagången", see https://sl.se/ficktid/karta/vinter/Gullmarsplan_term.pdf ) arriving in Dalbobranten at 18:12 . 

”A to B” where B is very close to A (same bus stop). Drinkstop and swimstop. Possible bbq afterwards at great lakeside location so bring your own Food!
