The next day we headed out of Costa Rica. Our next stop was to be Ometepe Island, in the middle of Lake Nicaragua. It’s the largest island in a freshwater lake in the world, and Lake Nicaragua is the largest lake in Central America. The island itself is made up of two volcanoes, one active, joined together by ancient lava flows. It can be seen from far away, the twin peaks rising from the waters of the lake. Before the Spanish arrived, the area was inhabited by the Nicarao tribe, who spoke Nahuatl, the language of the Aztecs. After a civil war in Mexico, the Nicarao people had fled south, and, on consulting their idols, were told that they should continue until they came to a huge expanse of fresh water with two mountains in the middle. Thus they settled on Ometepe and around the shores of the lake. The name Ometepe comes from the words Ome Tepetl, meaning ‘two hills’ in Nahuatl. Latin American border officials have never had the best reputation in the world, so we were a little daunted as we got the bus to Peñas Blancas for our first border of the journey. However, in the [...]

The next morning, we set out to explore the mountain. Rincón de la Vieja is at the centre of a region of great geothermal activity, and the evidence for subterranean heat is everywhere. A well-trodden trail winds past many geothermal features, and we set out along it. Before long we were temporarily out of the forest, and all around could see steam rising from the ground. It was quite a sight, and we set off in search of what was steaming. Over the next three hours or so, we passed hot pools of water, gently simmering and glooping pools of mud, warm streams, and a steaming hole in the ground which was rumbling and groaning ominously. We also saw a fearsomely boiling pool of mud known as Volcancito. It was quite a sight, and we couldn’t help but wonder just how far below us the magma here was. After seeing all that we could on the trail, we returned to our tents and had a magnificent pasta, tomato and tuna meal, before breaking camp. We had arranged to be picked up at the park’s other ranger station, 8km away, and we had four hours to do it in. We wanted [...]

We had spent enough time around Arenal, so the next day, we moved on to our next destination, Rincón de la Vieja. Situated in north western Costa Rica, this is another active volcano, which last erupted in 1998. We hoped to climb to the top and camp the night there. We made our way to Liberia, via the towns of Tilaran and Cañas. During the three-leg journey, the weather got ever hotter. As well as talking to a crazy young Costa Rican called Jorge, who would occasionally lean out the window and do tarzan whoops as we passed through the forest, we met two Austrian travellers, Andi and Eva, who also wanted to go to Rincón de la Vieja. We decided we’d all go up together, and decided to try and find a way there the next day. There is no public transport to Parque Nacional Rincón de la Vieja, but the owner of the hotel Moh and I were staying at had a 4WD, and said he’d take us to the park and pick us up the next day for $10 each. We hired him, and after we’d bought food and fuel, we set off. It was an awesomely [...]

We had met two Germans, Colom and Sylvia, down by the falls. Colom had a pickup truck, and when we saw that the volcano was visible, he said he would drive out towards it after nightfall, and invited us along. We gladly accepted. When darkness fell, a distinct orange glow could be seen over the volcano, and when Colom called around with his truck, we leapt keenly aboard. It was a spectacular drive out along the road past the volcano, with the wind in our hair, fireflies flashing around, and the volcano glowing high in the sky. However, as we watched, the clouds began to lower, and the volcano disappeared from view. Soon it was pelting down with rain. We sat inside the cab of the pickup until it had eased off, and then drove on. It was not long before the top of the volcano emerged again, and we decided to stop and watch it. All the rivers which run off the volcano are heated by the magma, and several places along the road here channel streams into pools. We stopped at one of these and sat in the thermal waters, watching the truly awesome sight of the volcano [...]

It was a spectacular run through misty mountain forests and small villages, with an awesome thunderstorm erupting overhead as we passed through Ciudad Quesada. We arrived at the small town of Fortuna late in the evening, and checked into a cheap hospedaje. We noticed for the first time how quickly night falls in the tropics when we walked outside 20 minutes later to find it was completely dark. Unfortunately, it was cloudy and we could see no sign of Volcán Arenal, which was the reason we’d come here. Volcán Arenal had caused no-one any bother until 1968, when it suddenly erupted violently, destroying a village and killing 78 people. Ever since then, though, it has been erupting constantly, with lava flowing constantly out of its crater. Occasionally larger eruptions take place – just three weeks before we arrived, three people had been killed by an unexpected explosion. We were pretty much certain of seeing eruptions here, if only the weather would clear up. The next morning was cloudy, though, so we got essentials like washing done, then went for a walk towards the volcano. No sign of eruptions, though, and we had not yet even seen the summit. We turned [...]

We had intended to depart for San Jose early the next day, but Jose said there was a great fruit market in Alajuela, so we went to that. It was a vibrant, colourful affair, with a beer tent and live music, and we had a great time buying lots of weird tropical fruits. I got horrifically sunburnt for the first time on the trip, but it had been a fun day so I didn’t mind. Eventually at about 4pm we left for San José. This meant we arrived just after dark, and it was raining. This is not really a sensible time to arrive in a big bustling Latin American capital, and it wasn’t long before we attracted unwanted attention. ‘Where you going?’ said a shifty looking character. ‘We’re looking for the Tica Linda hostel’ we said. He strode off purposefully, beckoning to us to follow him. Having no better plan, we did just that. He introduced himself as Patrick Fernandez, and said he hoped we’d enjoy Costa Rica. Friendly enough, but when he began walking down very dodgy looking streets, we began to worry. Then he walked into a dark unlit park, and we began to really worry. We [...]

Day 2, mission 1. Most of the population of Costa Rica live in a fertile valley in the central highlands called the Meseta Central. About 1500m above sea level, it is ringed by towering volcanoes. Some of them are active, and one of these is Volcán Poás. It stands 2704m tall in the middle of Parque Nacional Volcán Poas, and it last erupted in 1994, destroying what park facilities existed at the time. Since then, though, the number of tourists visiting Costa Rica every year has quadrupled to more than a million. Volcán Poás is a prime attraction, so they have rebuilt everything and put a paved road right to the very top. We went to the bus stop in Alajuela early in the morning, and got the bus to the crater. Our first sight of Costa Rica in the daylight was impressive – the fertile farmlands of the Meseta Central with dramatic cloud-capped peaks rising behind. After an increasingly bumpy two hour bus ride, we were at the top. A short walk led us to the edge of the crater, and far below was Poás’ amazingly turquoise crater lake, surrounded by a barren lunar landscape. The lake was steaming [...]

We had an inauspicious start to the trip. I’d arranged to meet Moh, who I would be travelling with, outside Smith’s on Victoria station, but unfortunately there are two Smith’s on Victoria station and we spent ages waiting for each other. Then we somehow managed to miss two Gatwick trains, for which there was no excuse. We made it to Gatwick in time for the flight, though, and had an untraumatic journey across the Atlantic and down the East coast of North America. Weather delayed us landing in Houston, but with just a little bit of panic and fast running, we made it onto the flight from there to San José, Costa Rica. I was a bit nervous as we flew south. Far below I could see towns in what must have been Mexico lighting up as darkness fell, and I could hardly begin to imagine what travelling in Central America might be like. My efforts at learning Spanish had not got beyond the appallingly basic, I didn’t really know if we’d got enough money with us, and I had no idea if the place would be crawling with tourists or if I wouldn’t see another foreigner for the next [...]
