Best Europe Group Tours for Summer 2026

By Russell Updated 24 Jul 2026
Key takeaways

A European summer costs more than the same trip in Asia — budget roughly £900£1,900 land-only for a week, with flights on top. For 18–35s the two staples are Greek-island hopping and Croatia sailing, and both deliver the classic summer scene. Peak July and August are the hottest, busiest and priciest weeks; June and September are the shoulder sweet spot — cheaper, quieter and still warm enough for the sea. If you want a sailing week or an August date, book early: those are the ones that sell out.

  • Realistic budget: £900£1,900 land-only for a week, flights on top.
  • The 18–35 staples: Greek-island hopping and Croatia sailing.
  • Peak July–August is hottest, busiest and dearest — book those dates early.
  • June and September are the shoulder sweet spot: cheaper, quieter, still warm.
  • Daily on-the-ground spend runs £50£90 — noticeably dearer than Asia.

What a European summer actually costs

There's no getting around it: a European summer costs more than the same length of trip in Southeast Asia. A one-week small-group tour lands somewhere between £900 and £1,900 land-only, and that's before you've added flights, food and drinks. The upside is short-haul airfares — a return from the UK is a fraction of a long-haul ticket, so the flights hurt far less here than they do on a winter escape to Asia.

The single biggest lever on the price is when you go. Peak July and August are the hottest and busiest weeks, and every operator prices accordingly — sailing weeks and August departures carry the top rates and fill first. June and September are the shoulder sweet spot: the sea is just as warm, the crowds thin out, and both tours and flights drop noticeably. The second lever is style. Croatia sailing weeks — one boat, one group, everything included — sit at the pricier end; Greek-island hopping by ferry is cheaper and gives you more independence. For the full picture of where these trips run, our Europe destination guide maps the routes.

How we chose

Every trip below is a real, currently-bookable departure pulled from our live catalogue. We ranked on genuine traveller rating and review volume first (so a 5★ with 100+ reviews outranks a 5★ with 40), then sanity-checked the all-in value for an 18–35 traveller: group age, what's actually included, and whether the from-price is honest. Prices are the lowest live land-only from-price at the time of writing and move with season and departure — always confirm on the operator's page before booking. We take no payment to rank a trip higher.

The best European summer tours for 18–35s

Five trips that consistently earn their reviews, spanning the flagship Croatia sailing week, the classic Greek-island runs and a walking-and-wine route through Italy. Each links straight through to the live departure so you can check dates and the current price.

1Most social

Croatia Sail Adventure

Best for The big, boat-based 18–35 summer week
5.0· 116 reviewsfrom £1,90010 days · INTRO Travel · starts Split

The flagship 18–35 sailing week — big, social and entirely boat-based, from Split down the Dalmatian coast. INTRO built their whole model around young travellers, so the group is age-matched and the party energy is dialled up. It's the priciest trip on this list land-only, but the included boat, route and nightlife are exactly what you're paying for, and a 5★ across 116 reviews backs it.

Dedicated 18–35 crowd, big social scene
5★ across 116 reviews
One boat, one group — everything sorted
Priciest option land-only
Boat-party energy won't suit everyone
2Best of Greece

Highlights of the Greek Islands

Best for The classic Greek-island run, done properly
5.0· 76 reviewsfrom £1,3608 days · G Adventures · starts Athens

The classic Greek-island loop from Athens, hitting the highlights over eight days without rushing them. G Adventures' local-guide network is the most consistent in the business, so the logistics of ferries and island transfers are handled for you. The group skews mixed-age and sociable rather than a pure party crowd — the pick if you want the islands more than the boat-party scene. A straight 5★ over 76 reviews.

3Best value Greece

Greek Island Hopping: Paros, Ios & Santorini Sunsets

Best for Nightlife on Ios and the Santorini sunset on a budget
5.0· 39 reviewsfrom £8957 days · G Adventures · starts Athens

The cheapest strong Greece pick on the list — seven days ferry-hopping Paros, Ios and Santorini for under £900 land-only. Ios brings the nightlife and Santorini brings the sunset everyone flies out for, so it packs the two things most 18–35s actually want into a single week. It's the budget end of G Adventures, so expect more independence and less hand-holding than the flagship runs.

Cheapest strong Greece option, under £900
Ios nightlife plus the Santorini sunsets
5★ across 39 reviews
Fewer reviews than the bigger tours
Budget setup — more independent, less included
4Best for Italy

Tuscany to Cinque Terre: Wines, Villages & Unforgettable Walks

Best for Wine, hill villages and coastal walking in Italy
5.0· 63 reviewsfrom £1,3457 days · G Adventures · starts Florence

The Italy pick if you'd rather walk, eat and drink your way through Tuscany than sit on a boat. Seven days from Florence through the wine country to the Cinque Terre coast, with the villages and the walks that make this stretch of Italy famous. It's a slower, more scenic trip than the Greek and Croatian party weeks — better suited to a mixed group who want the food and scenery over the nightlife. 5★ over 63 reviews.

Wine country plus the Cinque Terre coast

Croatia Sail — Split to Dubrovnik (The Southern Discovery)

Best for A cheaper, younger Croatia sailing week
5.0· 54 reviewsfrom £1,2858 days · Koda Sail · starts Split

The younger, cheaper alternative to the INTRO sailing week — eight days from Split to Dubrovnik on the Koda Sail boats. You get the same one-boat, one-crowd sailing scene down the Dalmatian coast for a good few hundred pounds less land-only. Koda skews to a younger, party-first crowd, so it's the pick if the social side matters more than a longer itinerary. 5★ over 54 reviews.

Cheaper than the INTRO sailing week
Younger, party-first sailing crowd

Shorter than the 10-day INTRO week
Party-boat energy won't suit everyone
Go in June or September and pay less for the same sea

The sea is just as warm either side of the peak, but the price isn't. June and September carry lower tour rates and noticeably cheaper flights than August, with far fewer crowds on the islands and the boats. If your dates are flexible, shifting a summer trip out of July–August is the single easiest way to spend less without giving anything up.

Sailing vs island-hopping — which suits you

Sailing weeks are the all-in option: one boat, one group, one crowd for the whole trip. Everything's sorted for you — the route, the transfers, where you sleep and, on the party boats, most of the nightlife — so you turn up and switch off. That's why they sit at the pricier end, and why the energy is relentlessly social: you're living with the same people for a week, so it's a big-group party or nothing. If that's the summer you want, a Croatia sailing week delivers it better than anything else.

Island-hopping is the looser, cheaper version. You move between islands by ferry, which means more independence — you can bolt on your own beach days, pick your own bars and skip anything that isn't for you — but also more logistics to manage yourself. It costs less because you're not paying for a private boat and crew, and the group tends to be more mixed. Neither is better; they're different holidays. Our Europe destination guide lays out both routes side by side.

Common questions

When is the cheapest time for a Europe summer trip?

June and September — the shoulder months either side of the peak. The sea is still warm, but tour rates and flights are noticeably cheaper than July and August, and the islands and boats are far less crowded. Peak July–August is the hottest and busiest window, and it's the priciest by some margin, so shift your dates out of it if you can.

Should I do a sailing week or island-hopping?

Sailing weeks are all-in and intensely social — one boat, one group, everything included — which is why they cost more. Island-hopping by ferry is cheaper and gives you more independence to build your own days, but you manage more of the logistics yourself. Pick sailing for the big-group party, island-hopping for freedom and a lower price.

How much does a Europe summer trip cost all-in?

The tour itself runs £900–£1,900 land-only for a week. On top of that, short-haul return flights from the UK are cheap by comparison — book early for August — and you'll spend roughly £50–£90 a day on food, drinks and extras, dearer than Asia. All-in, a genuinely good week lands somewhere around £1,600–£2,800 depending on the trip and season.

Are these tours only for 18–35s, and what's the group vibe?

It varies by operator. INTRO Travel and Koda Sail build specifically for the 18–35 crowd, so the sailing weeks are age-matched and party-first. G Adventures runs mixed-age small groups on the Greece and Italy trips — still sociable, just not a dedicated young-person scene. Each trip above notes which it is.
