Todays weather has more April weather than mid-summer weather about it! Heavy cloud and showers and Thunderstrorms will alternate with sunny spells - in short, typical April weather. Temperatures will only drop slightly.
By Wednesday the weather will improve again: It will become sunnier with still a risk of thunderstorms towards evening.
The Innsbruck MTB mountain hut tour at the foot of the Nordkette - with wonderful views over Tyrol's capital city and nearby village Rum. Follow the forestry road in Mühlau Forest towards Hungerburg or, alternatively, take the funicular or the J bus to the start. From here, take the Umbrüggler Almweg to the eponymous alpine hut. Then follow the signs along the pleasant forestry road (no climb needed) to Arzler Alm, and from here, continue along the track (slight climb) towards Rumer Alm. At the second junction, go through the barrier and follow the path on foot until you reach the forestry road again, and then it's just 10 minutes hard riding upwards to Rumer Alm. To return, take the forestry road back down towards Rechenhof and then follow the road to Innsbruck.
