Costa Rica Traverse

The trip was an amazing experience. As expected it was physically tough but worth every drop of sweat and mud (no blood fortunately). For me personally, I found the heat hard to adjust to. I expected us to benefit from the shade of the rainforest more than we did and I guess going from a Scottish winter to an equatorial country didn't help. Having said that it didn't detract from my enjoyment, just made it harder work. We were also lucky because all 13 of us got on very well and it was a good mix of people. A special mention has to go to the guides and Danny in particular. I remember when we did the Cycling in the Andes that the guides were good but Danny was excellent. As well as being extraordinarily fit and knowledgeable about adventure stuff he was passionate about Costa Rica, it's environment and future. He had a great sense of humour and as if all that weren't enough he and his team were superb cooks. Although this wasn't everyone's idea of a relaxing holiday I came home envigorated and motivated with stacks of energy - apart from having to negotiate Terminal 5 on it's second day of chaos! I've already been on your website looking for the next potential challenge, if only work didn't get in the way.

Responsible Litter Disposal

Responsible Litter Disposal in the Himalaya
Thanks to Tim Macartney-Snape, Leave No Trace

There are three categories of litter/garbage produced on a trek. Each type of litter needs to be dealt with differently.

1. Biodegradable: kitchen food waste

ACTION: These should be carried away from any camping areas and buried in an area away from any streams and preferably in deep leaf litter or a village compost heap.

2. Non‐combustible litter: steel, aluminium cans, aluminium foil, glass

ACTION: These should be carried back out to the road head and disposed of in a properly managed landfill site.

3. Combustible litter: paper plastic

ACTION: These can be burned but only in a well-designed incinerator so that no fire scar is left and also so that the burn is complete and clean.

These incinerators are used at our wilderness and eco-camps in Nepal and Bhutan.


Here’s a series of images of a clean burn. When the paper and plastic is fed slowly into the fire a complete and clean burn is the result. Only ashes remain. No scar on the earth.


 Are plastics safe to burn?

Most plastics taken on treks will be made purely from hydrocarbons such as polyethylene and polypropyleneThese are safe to burn and will only produce water and carbon dioxide if burned cleanly.

You should not burn PVC or Polystyrene as burning them can produce poisonous gases, these should be treated as non‐combustible.

Why burn litter?

Carrying out all litter on a long trek is expensive and impractical. Burning it in a controlled and managed way using a lightweight incinerator is clean and efficient, removing the possibility of that litter blowing or washing into the environment to be a risk to animals and creating an unsightly state to the landscape.

Responsible Litter Disposal in Peru and Mount Rinjani

On our treks in Peru and on Mount Rinjani our crew or muels carry all the litter collected over the course of the trek out from the trail and back to the nearest city to be responsibily disposed. 

In Cusco in Peru we worked with Turismo Cuida to ensure that our plastics are collected and delivered to the GIAMAT plant in Cusco, where the litter is sorted, packed and delivered to recycling plants in Lima.

In Indonesia the litter is taken to Lombok where it is delivered to the closest recycling plant.
