Lisbon, Lake Bled or the Ring Road: start by deciding whether you want to drive

A city break, a lakes-and-mountains region and a 1,300-kilometre loop are not rivals. They are three answers to one question about how much of the holiday is spent behind a wheel.

Put a Portuguese capital, a Slovenian lake district and an Icelandic circuit on the same page and the temptation is to score them. That produces nothing useful, because they are not substitutes in any sense a traveller recognises. What they do represent is three distinct trip mechanics, and the choice between them is settled almost entirely by one preference: whether driving is the holiday, an occasional convenience, or something to be avoided. Answer that honestly and two of these three fall away immediately. This piece works through what each demands logistically, what each charges, and where each one goes wrong.

Start with the wheel, not the scenery

Every practical difference between these three flows from transport. Lisbon is a walking and tram city where a hire car is an active liability, given the hills, the parking and the tolls. Bled and the Triglav area sit at the other end of a spectrum where a car meaningfully expands the trip but public buses cover the essentials. Iceland’s Ring Road is not a destination with driving attached; it is a driving route with destinations attached, and without a vehicle there is no trip at all.

That single distinction predicts cost, pace and risk more reliably than any comparison of sights. It also predicts who each suits: a nervous driver, a family with small children and a solo traveller will all reach different answers, and none of them is wrong.

Lisbon: no car, and a nightly charge you cannot avoid

The Portuguese capital charges a municipal tourist tax of 4 euros per person per night, capped at seven consecutive nights, with under-13s exempt. It doubled from 2 euros in September 2024. For a couple on a week that is 56 euros added to the accommodation, collected at the property rather than at booking.

The entry side has changed too. Portugal is inside the Schengen area, where the Entry/Exit System has been rolling out since 12 October 2025 and is due to be fully operational from 10 April 2026, replacing passport stamps with biometric records. The related travel authorisation scheme is a separate matter and was still expected in the final quarter of 2026, so it is not yet something to apply for. Anyone reading otherwise on a commercial website is being sold something that does not exist.

Bled and Triglav: a car helps, a bus will do

This is the most forgiving of the three for a traveller who does not want to drive daily. The lake is walkable, buses reach the main trailheads, and the region is small enough that a single base works for a week. The activity that most visitors come for is also the most regulated.

Vintgar Gorge charges 10 euros for adults, students and seniors, and 5 euros for children aged three to fifteen, with parking at 5 euros and a free shuttle from the official car parks to the visitor centre. Helmets are mandatory and issued at the centre, and there is a 50-euro penalty for walking the route in the wrong direction or for damaging or losing a helmet. Guided tours run daily at four in the afternoon at 28 euros for adults and 18 for children, with limited places. Shuttle users are asked to arrive 45 minutes before their entry time. Visits are advised against for under-threes because of the trail length.

The Ring Road is the trip, and it is unforgiving

Iceland’s charges are modest and its logistics are not. Accommodation tax runs at 800 kronur per night for hotels and guesthouses and 400 for campsites and mobile home pitches, and VAT sits at 24 per cent generally with a reduced 11 per cent band covering lodging, transport and food. The taxes are the least of it.

The FCDO’s driving guidance is unusually specific and worth taking at face value: gravel or dirt main routes, single-lane bridges with passing areas, river crossings to be taken at five to ten kilometres per hour, and winds that drive sand and ash into paintwork. It notes that British tourists have had to pay large amounts of money to repair hire car damage caused by sand and ash, which is a warning about insurance excess as much as about weather. Many highland tracks open only for a short part of the summer and several routes require four-wheel drive.

• Lisbon: 4 euros per person per night, capped at seven consecutive nights, under-13s exempt
• Vintgar Gorge: 10 euros adult admission, 5 euros for ages three to fifteen, 5 euros parking
• Iceland: 800 kronur nightly accommodation tax for hotels and guesthouses, 400 for campsites
• Schengen Entry/Exit System fully operational from 10 April 2026

What the volcano question actually means for a booking

The FCDO records a series of eruptions on the Reykjanes peninsula in the south-west since December 2023, the most recent of which began on 16 July 2025, and says further eruptions there are likely. The affected area is Grindavik and its immediate surroundings.

The practical reading is reassuring and should be stated plainly. The same advice confirms that Reykjavik, Keflavik International Airport and the rest of the country are unaffected. What it does warn against is walking on newly solidified lava, because the surface crust can break without warning. An eruption on that peninsula is an itinerary problem for one small corner of the south-west, not grounds to cancel a circuit of the island.

Three trips, three different ways to be ruined

Lisbon fails when the traveller stays only in the historic core, where a housing crisis has hollowed out the resident population and the streets have arranged themselves around visitors. The fix is easy and cheap: base yourself outside the postcard and use the trams inward.

Bled fails when the weather closes the mountains and the itinerary had nothing else in it, which is why a Slovenian week wants a Ljubljana day and a cave or two held in reserve. Iceland fails most expensively of all, because its failure mode is a closed road, a cancelled flight north or a hire car excess claim, and none of those can be absorbed by improvising. If the budget has no slack, the Ring Road is the wrong choice this year, and Slovenia is the sensible one.
