swisstopo publishes excellent free online maps at map.geo.admin.ch. Make sure to display the «Hiking trails» layer, and familiarize yourself with the signalization. If activating in winter, consider also the «Ski routes», «Snowshoe routes», «Wildlife reserves» and «Designated wildlife areas» layers. Keep in mind that the presence of a hiking, ski or snowshoe route does not mean that the summit is easy to get to, and alpine dangers (avalanches, crevasses, rockfall etc.) may be present.
…or the relative lack thereof. The freedom to roam is guaranteed by Swiss law, so you can activate HB summits without asking anyone for permission. Still, some restrictions apply for the protection of wildlife, especially in winter. Please see our Red Tape page for details.
Cable Car Summits
For the benefit of visitors coming to HB9-Land to activate SOTAs, Paul HB9DST has put together a list of so called «cable car summits» (this also includes other public transport such as cog railways).
