Italy on a backpacker budget for 21 days is the most achievable European shoestring destination, counter-intuitively, given Italy's reputation as an expensive country. The specific Italy backpacker insight: Italy has the most generous free cultural program of any major European country (the free churches (San Luigi dei Francesi with 3 Caravaggios, Santa Maria del Popolo with 2 Caravaggios, San Pietro in Vincoli with the Michelangelo Moses, all free), the free piazze, and the free markets constitute a daily cultural program that requires zero museum admission) AND the cheapest daily street food in Western Europe (the 1.30-euro espresso, the 1.50-euro cornetto, the 2-euro arancino, the 2.50-euro pizza al taglio per 100g, and the 3-euro market lunch from the alimentari (small grocery shop)). Under €50 per day (accommodation + food + transport + activities) for 21 days in Italy isn't a hardship, it is a specific strategic approach to the most rewarding shoestring destination in Europe.

Italy Backpacker 21 Days: The Route and the Daily Budget
Days 1-5: Rome (5 Nights)
Accommodation: the Alessandro Palace Hostel or the YHA Roma (the Foro Italico), approximately €22-28/night for a dorm bed. Free cultural program: San Clemente (the layered 4th-12th century church, free, the most historically stratified free Rome attraction), San Luigi dei Francesi (the 3 Caravaggio paintings, free), the Forum and Palatine Hill (paid, the one Rome paid site that justifies the backpacker budget allocation at €18 (combined Colosseum ticket optional, the Forum alone is €18)). Street food circuit: the supplì at Supplì Roma (the Via di San Francesco a Ripa 137. €2 each, the most specifically Roman fried rice ball), the pizza al taglio at Bonci Pizzarium (the Via della Meloria 43 near the Vatican. €3-4 per 100g, the most technically excellent pizza al taglio in Rome), and the mercato di Testaccio (the specific indoor market at the Piazza di Testaccio, the fresh pasta stalls, the cheese stalls, and the specific trippa alla romana (the Roman tripe) at the market's internal restaurant Mordi e Vai (the 5-euro Roman tripe sandwich, the most specifically authentic single Rome street food experience at the lowest single Rome cultural food price)).
Days 6-9: Naples and Pompeii (4 Nights)
Accommodation: the Spaccanapoli Hostel or the Hostel of the Sun (Piazza Garibaldi area, approximately €18-24/night dorm). The specific Naples free program: the Cappella di Sansevero (paid. €8, the Cristo Velato, the only Naples paid site the backpacker budget must prioritize), the Napoli Sotterranea (paid. €10, the Greek underground (see the dedicated guide)), and the free Naples: the entire Decumano Maggiore (Via dei Tribunali historic center walk, free), the San Lorenzo Maggiore (the free medieval-Gothic church above the Greek Agora ruins visible through the floor grating, the most specifically extraordinary free archaeological access in the Italian historic center network), and the specific Porta Nolana fish market (the early morning Tuesday-Saturday market (arrive 7:30-9:00), free visual spectacle and the most specifically Neapolitan market experience). Pompeii day trip: the Circumvesuviana from Napoli Porta Nolana (€2.80 one-way, 38 minutes) + the Pompeii Scavi admission (€16 for EU citizens under 18: free. Others: €16-18) = the highest single cultural-impact-to-price ratio in the entire Italy backpacker program.
Days 10-14: Puglia (5 Nights)
Accommodation: the Bari Hostel (Via Piccinni area, approximately €18-22/night) as the base for the Puglia circuit. The free Puglia program: the Bari Vecchia (the old Bari, the free exploration (the arched streets, the orecchiette women on the doorstep, the Basilica di San Nicola (free exterior and nave. The crypt requires the voluntary offering))). The Matera day trip (from Bari: the FlixBus Bari-Matera (€1.99-5 one-way, 1h15m) or the Ferrandina FAL (Ferrovie Appulo-Lucane) train + bus (the most specific but the most logistically complex connection)) + the Matera Sassi free circuit (the specific outdoor Sassi walking (the cave exterior is entirely publicly accessible, no admission charge for the Sasso Barisano and Sasso Caveoso outdoor circuit)). The Alberobello day trip (the FAL Bari-Alberobello train, €3.90 one-way, 1h15m, the trulli (the specific conical stone houses) are entirely visible and photographable from the public streets without admission charge).
Days 15-21: Sicily (7 Nights)
Accommodation: the Palermo Ballarò Hostel or the A'Putia Hostel (Palermo historic center, approximately €18-22/night). The Sicily free program: the Palermo Ballarò market (the most visually spectacular free Italian market), the Agrigento Valley of the Temples (the specific free dawn access (the Valley opens at 9:00 but the external circuit walk along Via Sacra fence provides the equivalent temple view from the road, the specific photographic position that the external road access provides is actually more dramatic for the wide-angle landscape than the interior circuit for certain compositions)), and the Ortigia (Siracusa) entire island (free exploration. Piazza del Duomo, the Fonte Aretusa, and the Porto Grande all accessible without charge).
