The Gran Vertical 2023 is a non-stop self-supported bikepacking event that proposes a 365-kilometre (227 mi) circuit that crosses four natural parks in the Spanish provinces of Tarragona, Teruel and Castellón. After participating in the two previous editions, I present here an adapted version. Divided into six stages, this Collection is designed so you can enjoy the journey without the time pressure of the original event – which has a time limit of 60 hours.

The route crosses unique and beautiful landscapes, including four natural parks: Els Ports, Tinença de Benifassà, Penyagolosa and Serra d'Irta. Starting and finishing in Amposta, next to the Ebro Delta, on the first day you’ll climb directly to the peaks of the Els Ports massif. Most of the 369 kilometres (229 mi) of the Collection are above 1,000 metres (3,000 ft), with a total of approximately 6,000 metres (20,000 ft) of elevation gain.

The landscapes are very varied; from the rocky massifs of Els Ports to the seafront of the Serra d'Irta to high plateaus such as the one that separates Teruel and Castellón, next to Penyagolosa natural park. The route allows you to appreciate the varied orography of the three provinces and offers impressive natural viewpoints, such as the Monlleó river ravine, the view of Xodos from Penyagolosa or the marvellous beaches of the Serra d'Irta.

Most of the route follows tracks in good condition, local roads and paved or dirt tracks. The route is designed for mountain bikes and is also suitable for gravel bikes. Although, if you opt for the latter, it’s advisable to use tyres of at least 42 millimetres with some luggage. In its original form, it’s a tough course, with some challenging sections. In the first stage, there’s an unavoidable 1-kilometre (0.6 mi) portage section. I have kept this short section as it’s the only way to connect the tracks on the seaside with those on the mountain side of Ports Natural Park. Elsewhere, I have varied some of the longer portage sections as there are viable alternatives away from the busiest roads.

Although the stages in this Collection always end in places where there are restaurants and accommodation, it’s advisable to book in advance as availability is limited in some places. At each stage, I have suggested establishments where you can stock up on supplies – advisable if you’re going to cover long distances without passing through towns where you can find services. The town of Amposta, where the Collection begins and ends, is well-connected by public transport. It has a bus and train station, with daily regional and medium-distance services, as well as being located next to the Mediterranean motorway.

The climate is Mediterranean, with mild winters and hot summers. However, in the mountainous areas it’s common to experience large temperature fluctuations throughout the day. Even in the warmer months, it’s essential to bring warm clothes and waterproofs, as early mornings and late nights can be chilly. The best time of year to complete this route is spring and autumn. In winter, snow is not uncommon in Els Ports, Tinença de Benifassà or Penyagolosa. In summer, daytime temperatures can be extreme.

In this Collection, you'll discover spectacular corners of these three Mediterranean provinces that combine landscapes of great contrasts. You'll need to be in good physical shape, but you'll be rewarded with marvellous views and an unforgettable experience.
