Mountain Warehouse Festival Fun 2-Man Tent
The Festival Fun 2-Man Tent from Mountain Warehouse is a brilliant starter tent. It's budget-friendly, easy to put up, and does a pretty decent job. You probably won't get more than a few uses out of it (weather dependant), but it's a great start. If you decide you love solo camping, you might want to upgrade to something a little more durable and weather-proof later on down the line. But this tent is ideal for a few short camping trips - I've used mine about 5 times now and it's done me proud every time.
Top Tip: practice putting your tent up at home before taking your first solo camping trip. That way you can make sure you have all the right pieces, and also make sure you know what you're doing, to save yourself running into difficulties when you arrive at the campsite!
