#4 Chill out on the lakeside park
Northwest of Piazza Cavour, a lakeside park curves along the water; it’s currently being refurbished (and has been for several years) but it’s worth persevering past the hoardings and going in.
Inside the Tempio Voltiano, dedicated to Alessandro Volta, a Como man and pioneer in electricity who gave his name to the volt, there’s a small museum displaying some of his instruments. Next door, the stark Monumento ai Caduti, a memorial to the dead of World War I, was built by Terragni to the design of the Futurist architect Antonio Sant’Elia, who was killed in 1916 aged 28.
Ten minutes’ walk beyond, past the Seaplane hangar, the Villa Olmo is a Neoclassical pile which is compellingly illuminated at night. It hosts conferences and temporary exhibitions, but its gardens (open daily; free) are the biggest draw.
#5 Get the funicular to hilltop Brunate
From the base station of the funicular northwest from Piazza Cavour, it takes seven minutes to creep up the hillside past the gardens of wonderful nineteenth-century villas to Brunate, a small hilltop resort that has a few bars and restaurants and great views of the lake. It is also a good starting point for hikes – from a couple of hours to a two-day trip along mule paths to Bellagio; the tourist office has details of routes.
